Pull VFIO updates from Alex Williamson:

 - Add warning in unlikely case that device is not captured with
   driver_override (Kunwu Chan)

 - Error handling improvements in mlx5-vfio-pci to detect firmware
   tracking object error states, logging of firmware error syndrom, and
   releasing of firmware resources in aborted migration sequence (Yishai
   Hadas)

 - Correct an un-alphabetized VFIO MAINTAINERS entry (Alex Williamson)

 - Make the mdev_bus_type const and also make the class struct const for
   a couple of the vfio-mdev sample drivers (Ricardo B. Marliere)

 - Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
   Grace-Hopper superchip. During initialization of the chip-to-chip
   interconnect in this hardware module, the PCI BARs of the device
   become unused in favor of a faster, coherent mechanism for exposing
   device memory. This driver primarily changes the VFIO representation
   of the device to masquerade this coherent aperture to replace the
   physical PCI BARs for userspace drivers. This also incorporates use
   of a new vma flag allowing KVM to use write combining attributes for
   uncached device memory (Ankit Agrawal)

 - Reset fixes and cleanups for the pds-vfio-pci driver. Save and
   restore files were previously leaked if the device didn't pass
   through an error state, this is resolved and later re-fixed to
   prevent access to the now freed files. Reset handling is also
   refactored to remove the complicated deferred reset mechanism (Brett
   Creeley)

 - Remove some references to pl330 in the vfio-platform amba driver
   (Geert Uytterhoeven)

 - Remove twice redundant and ugly code to unpin incidental pins of the
   zero-page (Alex Williamson)

 - Deferred reset logic is also removed from the hisi-acc-vfio-pci
   driver as a simplification (Shameer Kolothum)

 - Enforce that mlx5-vfio-pci devices must support PRE_COPY and remove
   resulting unnecessary code. There is no device firmware that has been
   available publicly without this support (Yishai Hadas)

 - Switch over to using the .remove_new callback for vfio-platform in
   support of the broader transition for a void remove function (Uwe
   Kleine-König)

 - Resolve multiple issues in interrupt code for VFIO bus drivers that
   allow calling eventfd_signal() on a NULL context. This also remove a
   potential race in INTx setup on certain hardware for vfio-pci, races
   with various mechanisms to mask INTx, and leaked virqfds in
   vfio-platform (Alex Williamson)

Pull kvm updates from Paolo Bonzini:
 "S390:

   - Changes to FPU handling came in via the main s390 pull request

   - Only deliver to the guest the SCLP events that userspace has
     requested

   - More virtual vs physical address fixes (only a cleanup since
     virtual and physical address spaces are currently the same)

   - Fix selftests undefined behavior

  x86:

   - Fix a restriction that the guest can't program a PMU event whose
     encoding matches an architectural event that isn't included in the
     guest CPUID. The enumeration of an architectural event only says
     that if a CPU supports an architectural event, then the event can
     be programmed *using the architectural encoding*. The enumeration
     does NOT say anything about the encoding when the CPU doesn't
     report support the event *in general*. It might support it, and it
     might support it using the same encoding that made it into the
     architectural PMU spec

   - Fix a variety of bugs in KVM's emulation of RDPMC (more details on
     individual commits) and add a selftest to verify KVM correctly
     emulates RDMPC, counter availability, and a variety of other
     PMC-related behaviors that depend on guest CPUID and therefore are
     easier to validate with selftests than with custom guests (aka
     kvm-unit-tests)

   - Zero out PMU state on AMD if the virtual PMU is disabled, it does
     not cause any bug but it wastes time in various cases where KVM
     would check if a PMC event needs to be synthesized

   - Optimize triggering of emulated events, with a nice ~10%
     performance improvement in VM-Exit microbenchmarks when a vPMU is
     exposed to the guest

   - Tighten the check for "PMI in guest" to reduce false positives if
     an NMI arrives in the host while KVM is handling an IRQ VM-Exit

   - Fix a bug where KVM would report stale/bogus exit qualification
     information when exiting to userspace with an internal error exit
     code

   - Add a VMX flag in /proc/cpuinfo to report 5-level EPT support

   - Rework TDP MMU root unload, free, and alloc to run with mmu_lock
     held for read, e.g. to avoid serializing vCPUs when userspace
     deletes a memslot

   - Tear down TDP MMU page tables at 4KiB granularity (used to be
     1GiB). KVM doesn't support yielding in the middle of processing a
     zap, and 1GiB granularity resulted in multi-millisecond lags that
     are quite impolite for CONFIG_PREEMPT kernels

   - Allocate write-tracking metadata on-demand to avoid the memory
     overhead when a kernel is built with i915 virtualization support
     but the workloads use neither shadow paging nor i915 virtualization

   - Explicitly initialize a variety of on-stack variables in the
     emulator that triggered KMSAN false positives

   - Fix the debugregs ABI for 32-bit KVM

   - Rework the "force immediate exit" code so that vendor code
     ultimately decides how and when to force the exit, which allowed
     some optimization for both Intel and AMD

   - Fix a long-standing bug where kvm_has_noapic_vcpu could be left
     elevated if vCPU creation ultimately failed, causing extra
     unnecessary work

   - Cleanup the logic for checking if the currently loaded vCPU is
     in-kernel

   - Harden against underflowing the active mmu_notifier invalidation
     count, so that "bad" invalidations (usually due to bugs elsehwere
     in the kernel) are detected earlier and are less likely to hang the
     kernel

  x86 Xen emulation:

   - Overlay pages can now be cached based on host virtual address,
     instead of guest physical addresses. This removes the need to
     reconfigure and invalidate the cache if the guest changes the gpa
     but the underlying host virtual address remains the same

   - When possible, use a single host TSC value when computing the
     deadline for Xen timers in order to improve the accuracy of the
     timer emulation

   - Inject pending upcall events when the vCPU software-enables its
     APIC to fix a bug where an upcall can be lost (and to follow Xen's
     behavior)

   - Fall back to the slow path instead of warning if "fast" IRQ
     delivery of Xen events fails, e.g. if the guest has aliased xAPIC
     IDs

  RISC-V:

   - Support exception and interrupt handling in selftests

   - New self test for RISC-V architectural timer (Sstc extension)

   - New extension support (Ztso, Zacas)

   - Support userspace emulation of random number seed CSRs

  ARM:

   - Infrastructure for building KVM's trap configuration based on the
     architectural features (or lack thereof) advertised in the VM's ID
     registers

   - Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
     x86's WC) at stage-2, improving the performance of interacting with
     assigned devices that can tolerate it

   - Conversion of KVM's representation of LPIs to an xarray, utilized
     to address serialization some of the serialization on the LPI
     injection path

   - Support for _architectural_ VHE-only systems, advertised through
     the absence of FEAT_E2H0 in the CPU's ID register

   - Miscellaneous cleanups, fixes, and spelling corrections to KVM and
     selftests

  LoongArch:

   - Set reserved bits as zero in CPUCFG

   - Start SW timer only when vcpu is blocking

   - Do not restart SW timer when it is expired

   - Remove unnecessary CSR register saving during enter guest

   - Misc cleanups and fixes as usual

  Generic:

   - Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically
     always true on all architectures except MIPS (where Kconfig
     determines the available depending on CPU capabilities). It is
     replaced either by an architecture-dependent symbol for MIPS, and
     IS_ENABLED(CONFIG_KVM) everywhere else

   - Factor common "select" statements in common code instead of
     requiring each architecture to specify it

   - Remove thoroughly obsolete APIs from the uapi headers

   - Move architecture-dependent stuff to uapi/asm/kvm.h

   - Always flush the async page fault workqueue when a work item is
     being removed, especially during vCPU destruction, to ensure that
     there are no workers running in KVM code when all references to
     KVM-the-module are gone, i.e. to prevent a very unlikely
     use-after-free if kvm.ko is unloaded

   - Grab a reference to the VM's mm_struct in the async #PF worker
     itself instead of gifting the worker a reference, so that there's
     no need to remember to *conditionally* clean up after the worker

  Selftests:

   - Reduce boilerplate especially when utilize selftest TAP
     infrastructure

   - Add basic smoke tests for SEV and SEV-ES, along with a pile of
     library support for handling private/encrypted/protected memory

   - Fix benign bugs where tests neglect to close() guest_memfd files"

   - The ssfdc driver received few minor adjustments

   - The usual load of misc/small improvements and fixes

  Raw NAND:

   - The main series brought is an update of the Broadcom support to
     support all BCMBCA SoCs and their specificity (ECC, write
     protection, configuration straps), plus a few misc fixes and
     changes in the main driver. Device tree updates are also part of
     this PR, initially because of a misunderstanding on my side.

   - The STM32_FMC2 controller driver is also upgraded to properly
     support MP1 and MP25 SoCs.

   - A new compatible is added for an Atmel flavor.

   - Among all these feature changes, there is as well a load of
     continuous read related fixes, avoiding more corner conditions and
     clarifying the logic. Finally a few miscellaneous fixes are made to
     the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller
     driver, as well as final one in the Hynix vendor driver.

  SPI-NAND:

   - The ESMT support has been extended to match 5 bytes ID to avoid
     collisions. Winbond support on its side receives support for
     W25N04KV chips.

  SPI NOR:

   - SPI NOR gets the non uniform erase code cleaned. We stopped using
     bitmasks for erase types and flags, and instead introduced
     dedicated members. We then passed the SPI NOR erase map to MTD.
     Users can now determine the erase regions and make informed

Pull clk updates from Stephen Boyd:
 "Not a ton of stuff happening in the clk framework. We got some more
  devm helpers and we seem to be going in the direction of "just turn
  this stuff on already and leave me alone!" with the addition of a
  devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that
  into a pmdomain that drivers attach instead, but this API should help
  drivers simplify in the meantime.

  Outside of the devm wrappers, we've got the usual clk driver updates
  that are dominated by the major phone SoC vendors (Samsung and
  Qualcomm) and the non-critical driver fixes for things like incorrect
  topology descriptions and wrong registers or bit fields. More details
  are below, but I'd say that it looks pretty ordinary. The only thing
  that really jumps out at me is the Renesas clk driver that's ignoring
  clks that are assigned to remote processors in DeviceTree. That's a
  new feature that they're using to avoid marking clks as
  CLK_IGNORE_UNUSED based on the configuration of the system.

  Core:
   - Increase dev_id len for clkdev lookups
   - Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
     for a device
   - Add a devm variant of clk_rate_exclusive_get()

  New Drivers:
   - Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1
     Elite SoC
   - Google GS101 PERIC0 and PERIC1 clock controllers
   - Exynos850 PDMA clocks
   - Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock
     controllers

  Removed Drivers:
   - Remove the unused Qualcomm sc7180 modem clk driver

  Updates:
   - Fix some static checker errors in the Hisilicon clk driver
   - Polarfire MSSPLL hardware has 4 output clocks (the driver supported
     previously only one output); each of these 4 outputs feed dividers
     and the output of each divider feed individual hardware blocks
     (e.g. CAN, Crypto, eMMC); individual hardware block drivers need to
     control their clocks thus clock driver support was added for all
     MSSPLL output clocks
   - Typo fixes in the Qualcomm IPQ5018 GCC driver
   - Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
   - Properly terminate frequency tables in different Qualcomm clk
     drivers
   - Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
   - Add missing UFS CLKREF clks on Qualcomm SC8180X
   - Avoid significant delays during boot by adding a softdep on rpmhpd
     to Qualcomm SDM845 gcc driver
   - Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC
     driver
   - Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC
     driver
   - Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk
     driver
   - Switch display, GPU, video, and camera Qualcomm clk drivers to
     module_platform_driver()
   - Set a longer delay for Venus resets on many Qualcomm SoCs
   - Correct the GDSC wait times in the Qualcomm SDM845 display clk
     driver
   - Fix clock listing Oops on Amlogic axg
   - New pll-rate for Rockchip rk3568
   - i2s rate improvements for Rockchip rk3399
   - Rockchip rk3588 syscon clock fixes and removal of overall
     clock-number from the rk3588 binding header
   - A prerequisite for later improvements to the Rockchip rk3588 linked
     clocks
   - Minor clean-ups and error handling improvements in both
     composite-8m and SCU i.MX clock drivers
   - Fix for SAI_MCLK_SEL definition for i.MX8MP
   - Register the Samsung CMU MISC clock controller earlier, so the
     Multi Core Timer clocksource can use it on Google GS101
   - Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI
     will get proper clock rates
   - Refactor the generic Samsung CPU clock controllers code, preparing
     it for supporting Exynos850 CPU clocks
   - Fix some clk kerneldoc warnings
   - Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on
     Renesas R-Car V4M
   - Ignore all clocks which are assigned to a non-Linux system in the
     Renesas clk driver
   - Add watchdog clock on Renesas RZ/G3S
   - Add camera (CRU) clock and reset on Renesas RZ/G2UL
   - Add support for the Renesas R-Car V4M (R8A779H0) SoC
   - Convert some clk bindings to YAML so they can be validated"

Raw NAND

The main series brought is an update of the Broadcom support to support
all BCMBCA SoCs and their specificity (ECC, write protection,
configuration straps), plus a few misc fixes and changes in the main
driver. Device tree updates are also part of this PR, initially because
of a misunderstanding on my side.

The STM32_FMC2 controller driver is also upgraded to properly support
MP1 and MP25 SoCs.

A new compatible is added for an Atmel flavor.

Among all these feature changes, there is as well a load of continuous
read related fixes, avoiding more corner conditions and clarifying the
logic. Finally a few miscellaneous fixes are made to the core, the
lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as
final one in the Hynix vendor driver.

SPI-NAND

The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for W25N04KV
chips.

$(shell ...) expands to the output of the command. It expands to the
empty string when the command does not print anything to stdout.
Hence, $(shell mkdir ...) is sufficient and does not need any
variable assignment in front of it.

Commit c2bd08ba ("treewide: remove meaningless assignments in
Makefiles", 2024-02-23) did this to all of tools/ but ignored in-flight
changes to tools/testing/selftests/kvm/Makefile, so reapply the change.

 - Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
   from hotplugged memory rather than only from main memory. Series
   "implement "memmap on memory" feature on s390".

 - More folio conversions from Matthew Wilcox in the series

	"Convert memcontrol charge moving to use folios"
	"mm: convert mm counter to take a folio"

 - Chengming Zhou has optimized zswap's rbtree locking, providing
   significant reductions in system time and modest but measurable
   reductions in overall runtimes. The series is "mm/zswap: optimize the
   scalability of zswap rb-tree".

 - Chengming Zhou has also provided the series "mm/zswap: optimize zswap
   lru list" which provides measurable runtime benefits in some
   swap-intensive situations.

 - And Chengming Zhou further optimizes zswap in the series "mm/zswap:
   optimize for dynamic zswap_pools". Measured improvements are modest.

 - zswap cleanups and simplifications from Yosry Ahmed in the series
   "mm: zswap: simplify zswap_swapoff()".

 - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
   contributed several DAX cleanups as well as adding a sysfs tunable to
   control the memmap_on_memory setting when the dax device is
   hotplugged as system memory.

 - Johannes Weiner has added the large series "mm: zswap: cleanups",
   which does that.

 - More DAMON work from SeongJae Park in the series

	"mm/damon: make DAMON debugfs interface deprecation unignorable"
	"selftests/damon: add more tests for core functionalities and corner cases"
	"Docs/mm/damon: misc readability improvements"
	"mm/damon: let DAMOS feeds and tame/auto-tune itself"

 - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
   extension" Rakie Kim has developed a new mempolicy interleaving
   policy wherein we allocate memory across nodes in a weighted fashion
   rather than uniformly. This is beneficial in heterogeneous memory
   environments appearing with CXL.

 - Christophe Leroy has contributed some cleanup and consolidation work
   against the ARM pagetable dumping code in the series "mm: ptdump:
   Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".

 - Luis Chamberlain has added some additional xarray selftesting in the
   series "test_xarray: advanced API multi-index tests".

 - Muhammad Usama Anjum has reworked the selftest code to make its
   human-readable output conform to the TAP ("Test Anything Protocol")
   format. Amongst other things, this opens up the use of third-party
   tools to parse and process out selftesting results.

 - Ryan Roberts has added fork()-time PTE batching of THP ptes in the
   series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
   targeted at arm64, this significantly speeds up fork() when the
   process has a large number of pte-mapped folios.

 - David Hildenbrand also gets in on the THP pte batching game in his
   series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
   implements batching during munmap() and other pte teardown
   situations. The microbenchmark improvements are nice.

 - And in the series "Transparent Contiguous PTEs for User Mappings"
   Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte
   mappings"). Kernel build times on arm64 improved nicely. Ryan's
   series "Address some contpte nits" provides some followup work.

 - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
   fixed an obscure hugetlb race which was causing unnecessary page
   faults. He has also added a reproducer under the selftest code.

 - In the series "selftests/mm: Output cleanups for the compaction
   test", Mark Brown did what the title claims.

 - Kinsey Ho has added the series "mm/mglru: code cleanup and
   refactoring".

 - Even more zswap material from Nhat Pham. The series "fix and extend
   zswap kselftests" does as claimed.

 - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
   regression" Mathieu Desnoyers has cleaned up and fixed rather a mess
   in our handling of DAX on archiecctures which have virtually aliasing
   data caches. The arm architecture is the main beneficiary.

 - Lokesh Gidra's series "per-vma locks in userfaultfd" provides
   dramatic improvements in worst-case mmap_lock hold times during
   certain userfaultfd operations.

 - Some page_owner enhancements and maintenance work from Oscar Salvador
   in his series

	"page_owner: print stacks and their outstanding allocations"
	"page_owner: Fixup and cleanup"

 - Uladzislau Rezki has contributed some vmalloc scalability
   improvements in his series "Mitigate a vmap lock contention". It
   realizes a 12x improvement for a certain microbenchmark.

 - Some kexec/crash cleanup work from Baoquan He in the series "Split
   crash out from kexec and clean up related config items".

 - Some zsmalloc maintenance work from Chengming Zhou in the series

	"mm/zsmalloc: fix and optimize objects/page migration"
	"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"

 - Zi Yan has taught the MM to perform compaction on folios larger than
   order=0. This a step along the path to implementaton of the merging
   of large anonymous folios. The series is named "Enable >0 order folio
   memory compaction".

 - Christoph Hellwig has done quite a lot of cleanup work in the
   pagecache writeback code in his series "convert write_cache_pages()
   to an iterator".

 - Some modest hugetlb cleanups and speedups in Vishal Moola's series
   "Handle hugetlb faults under the VMA lock".

 - Zi Yan has changed the page splitting code so we can split huge pages
   into sizes other than order-0 to better utilize large folios. The
   series is named "Split a folio to any lower order folios".

 - David Hildenbrand has contributed the series "mm: remove
   total_mapcount()", a cleanup.

 - Matthew Wilcox has sought to improve the performance of bulk memory
   freeing in his series "Rearrange batched folio freeing".

 - Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
   provides large improvements in bootup times on large machines which
   are configured to use large numbers of hugetlb pages.

 - Matthew Wilcox's series "PageFlags cleanups" does that.

 - Qi Zheng's series "minor fixes and supplement for ptdesc" does that
   also. S390 is affected.

 - Cleanups to our pagemap utility functions from Peter Xu in his series
   "mm/treewide: Replace pXd_large() with pXd_leaf()".

 - Nico Pache has fixed a few things with our hugepage selftests in his
   series "selftests/mm: Improve Hugepage Test Handling in MM
   Selftests".

 - Also, of course, many singleton patches to many things. Please see
   the individual changelogs for details.

        --- start ---

   - Support Power11 PVR (compatible to Power10)

   - Fix cache latency events on Zen 4 to set SliceId properly

  Internal:

   - Fix reference counting for 'map' data structure, tireless work from
     Ian!

   - More memory optimization for struct thread and annotate histogram.
     Now, 'perf report' (TUI) and 'perf annotate' should be much
     lighter-weight in terms of memory footprint

   - Support cross-arch perf register access. Clean up the build
     configuration so that it can detect arch-register support at
     runtime. This can allow to parse register data in sample which was
     recorded in a different arch

  Others:

   - Sync task state in 'perf sched' to kernel using trace event fields.
     The task states have been changed so tools cannot assume a fixed
     encoding

   - Clean up 'perf mem' to generalize the arch-specific events

   - Add support for local and global variables to data type profiling.
     This would increase the success rate of type resolution with DWARF

   - Add short option -H for --hierarchy in 'perf report' and 'perf top'"

Merge tag 'trace-ring-buffer-v6.8-rc7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing updates from Steven Rostedt:

 - Do not update shortest_full in rb_watermark_hit() if the watermark is
   hit. The shortest_full field was being updated regardless if the task
   was going to wait or not. If the watermark is hit, then the task is
   not going to wait, so do not update the shortest_full field (used by
   the waker).

 - Update shortest_full field before setting the full_waiters_pending
   flag

   In the poll logic, the full_waiters_pending flag was being set before
   the shortest_full field was set. If the full_waiters_pending flag is
   set, writers will check the shortest_full field which has the least
   percentage of data that the ring buffer needs to be filled before
   waking up. The writer will check shortest_full if
   full_waiters_pending is set, and if the ring buffer percentage filled
   is greater than shortest full, then it will call the irq_work to wake
   up the waiters.

   The problem was that the poll logic set the full_waiters_pending flag
   before updating shortest_full, which when zero will always trigger
   the writer to call the irq_work to wake up the waiters. The irq_work
   will reset the shortest_full field back to zero as the woken waiters
   is suppose to reset it.

 - There's some optimized logic in the rb_watermark_hit() that is used
   in ring_buffer_wait(). Use that helper function in the poll logic as
   well.

 - Restructure ring_buffer_wait() to use wait_event_interruptible()

   The logic to wake up pending readers when the file descriptor is
   closed is racy. Restructure ring_buffer_wait() to allow callers to
   pass in conditions besides the ring buffer having enough data in it
   by using wait_event_interruptible().

 - Update the tracing_wait_on_pipe() to call ring_buffer_wait() with its
   own conditions to exit the wait loop.

Pull probes updates from Masami Hiramatsu:
 "x86 kprobes:

   - Use boolean for some function return instead of 0 and 1

   - Prohibit probing on INT/UD. This prevents user to put kprobe on
     INTn/INT1/INT3/INTO and UD0/UD1/UD2 because these are used for a
     special purpose in the kernel

   - Boost Grp instructions. Because a few percent of kernel
     instructions are Grp 2/3/4/5 and those are safe to be executed
     without ip register fixup, allow those to be boosted (direct
     execution on the trampoline buffer with a JMP)

  tracing:

   - Add function argument access from return events (kretprobe and
     fprobe). This allows user to compare how a data structure field is
     changed after executing a function. With BTF, return event also
     accepts function argument access by name.

   - Fix a wrong comment (using "Kretprobe" in fprobe)

   - Cleanup a big probe argument parser function into three parts, type
     parser, post-processing function, and main parser

   - Cleanup to set nr_args field when initializing trace_probe instead
     of counting up it while parsing

Pull lsm fixes from Paul Moore:
 "Two fixes to address issues with the LSM syscalls that we shipped in
  Linux v6.8. The first patch might be a bit controversial, but the
  second is a rather straightforward fix; more on both below.

  The first fix from Casey addresses a problem that should have been
  caught during the ~16 month (?) review cycle, but sadly was not. The
  good news is that Dmitry caught it very quickly once Linux v6.8 was
  released. The core issue is the use of size_t parameters to pass
  buffer sizes back and forth in the syscall; while we could have solved
  this with a compat syscall definition, given the newness of the
  syscalls I wanted to attempt to just redefine the size_t parameters as
  u32 types and avoid the work associated with a set of compat syscalls.

  However, this is technically a change in the syscall's signature/API
  so I can understand if you're opposed to this, even if the syscalls
  are less than a week old.

   [ Fingers crossed nobody even notices - Linus ]

  The second fix is a rather trivial fix to allow userspace to call into
  the lsm_get_self_attr() syscall with a NULL buffer to quickly
  determine a minimum required size for the buffer. We do have
  kselftests for this very case, I'm not sure why I didn't notice the
  failure; I'm going to guess stupidity, tired eyes, I dunno. My
  apologies we didn't catch this earlier"

The cont_read.ongoing flag should only be enabled at the beginning of a
read operation, and also disabled at its end, so we never end up
triggering nasty side effects outside of this scope. The mtd core being
highly serialized, we should not be bothered by parallel accesses
anyway.

In case we reach the end of a read operation and the boolean was not
properly disabled, it's a bug, but it's totally manageable. So warn, and
then fix the boolean state.

As a matter of fact, continuous reads require additional handling at the
operation level in order for them to work properly. The core helpers do
have this additional logic now, but any time a controller implements its
own page helper, this extra logic is "lost". This means we need another
level of per-controller driver checks to ensure they can leverage
continuous reads. This is for now unsupported, so in order to ensure
continuous reads are enabled only when fully using the core page
helpers, we need to add more initial checks.

Also, as performance is not relevant during raw accesses, we also
prevent these from enabling the feature.

This should solve the issue seen with controllers such as the STM32 FMC2
when in sequencer mode. In this case, the continuous read feature would
be enabled but not leveraged, and most importantly not disabled, leading
to further operations to fail.

While crossing a LUN boundary, it is probably safer (and clearer) to
keep all members of the continuous read structure aligned, including the
pause page (which is the last page of the lun or the last page of the
continuous read). Once these members properly in sync, we can use the
rawnand_cap_cont_reads() helper everywhere to "prepare" the next
continuous read if there is one.
