When plain IBRS is enabled (not enhanced IBRS), the logic in
spectre_v2_user_select_mitigation() determines that STIBP is not needed.

The IBRS bit implicitly protects against cross-thread branch target
injection. However, with legacy IBRS, the IBRS bit is cleared on
returning to userspace for performance reasons which leaves userspace
threads vulnerable to cross-thread branch target injection against which
STIBP protects.

Exclude IBRS from the spectre_v2_in_ibrs_mode() check to allow for
enabling STIBP (through seccomp/prctl() by default or always-on, if
selected by spectre_v2_user kernel cmdline parameter).

The results of "access_ok()" can be mis-speculated.  The result is that
you can end speculatively:

	if (access_ok(from, size))
		// Right here

even for bad from/size combinations.  On first glance, it would be ideal
to just add a speculation barrier to "access_ok()" so that its results
can never be mis-speculated.

But there are lots of system calls just doing access_ok() via
"copy_to_user()" and friends (example: fstat() and friends).  Those are
generally not problematic because they do not _consume_ data from
userspace other than the pointer.  They are also very quick and common
system calls that should not be needlessly slowed down.

"copy_from_user()" on the other hand uses a user-controller pointer and
is frequently followed up with code that might affect caches.  Take
something like this:

	if (!copy_from_user(&kernelvar, uptr, size))
		do_something_with(kernelvar);

If userspace passes in an evil 'uptr' that *actually* points to a kernel
addresses, and then do_something_with() has cache (or other)
side-effects, it could allow userspace to infer kernel data values.

Add a barrier to the common copy_from_user() code to prevent
mis-speculated values which happen after the copy.

Also add a stub for architectures that do not define barrier_nospec().
This makes the macro usable in generic code.

Since the barrier is now usable in generic code, the x86 #ifdef in the
BPF code can also go away.

Pull thermal control updates from Rafael Wysocki:
 "The majority of changes here are related to the general switch-over to
  using arrays of generic trip point structures registered along with a
  thermal zone instead of trip point callbacks (this has been done
  mostly by Daniel Lezcano with some help from yours truly on the Intel
  drivers front).

  Apart from that and the related reorganization of code, there are some
  enhancements of the existing driver and a new Mediatek Low Voltage
  Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
  rework so it will use the generic idle_inject facility for CPU idle
  time injection going forward and it will take additional module
  parameters for specifying the subset of CPUs to be affected by it
  (work done by Srinivas Pandruvada).

  Also included are assorted fixes and a whole bunch of cleanups.

  Specifics:

   - Rework a large bunch of drivers to use the generic thermal trip
     structure and use the opportunity to do more cleanups by removing
     unused functions from the OF code (Daniel Lezcano)

   - Remove core header inclusion from drivers (Daniel Lezcano)

   - Fix some locking issues related to the generic thermal trip rework
     (Johan Hovold)

   - Fix a crash when requesting the critical temperature on tegra,
     which is related to the generic trip point work (Jon Hunter)

   - Clean up thermal device unregistration code (Viresh Kumar)

   - Fix and clean up thermal control core initialization error code
     paths (Daniel Lezcano)

   - Relocate the trip points handling code into a separate file (Daniel
     Lezcano)

   - Make the thermal core fail registration of thermal zones and
     cooling devices if the thermal class has not been registered
     (Rafael Wysocki)

   - Add trip point initialization helper functions for ACPI-defined
     trip points and modify two thermal drivers to use them (Rafael
     Wysocki, Daniel Lezcano)

   - Make the core thermal control code use sysfs_emit_at() instead of
     scnprintf() where applicable (ye xingchen)

   - Consolidate code accessing the Intel TCC (Thermal Control
     Circuitry) MSRs by introducing library functions for that and
     making the TCC-related code in thermal drivers use them (Zhang Rui)

   - Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
     changes (Zhang Rui)

   - Address an "unsigned expression compared with zero" warning in the
     intel_soc_dts_iosf thermal driver (Yang Li)

   - Update comments regarding two functions in the Intel Menlow thermal
     driver (Deming Wang)

   - Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
     driver (ye xingchen)

   - Make the intel_pch thermal driver support the Wellsburg PCH (Tim
     Zimmermann)

   - Modify the intel_pch and processor_thermal_device_pci thermal
     drivers use generic trip point tables instead of thermal zone trip
     point callbacks (Daniel Lezcano)

   - Add production mode attribute sysfs attribute to the int340x
     thermal driver (Srinivas Pandruvada)

   - Rework dynamic trip point updates handling and locking in the
     int340x thermal driver (Rafael Wysocki)

   - Make the int340x thermal driver use a generic trip points table
     instead of thermal zone trip point callbacks (Rafael Wysocki,
     Daniel Lezcano)

   - Clean up and improve the int340x thermal driver (Rafael Wysocki)

   - Simplify and clean up the intel_pch thermal driver (Rafael Wysocki)

   - Fix the Intel powerclamp thermal driver and make it use the common
     idle injection framework (Srinivas Pandruvada)

   - Add two module parameters, cpumask and max_idle, to the Intel
     powerclamp thermal driver to allow it to affect only a specific
     subset of CPUs instead of all of them (Srinivas Pandruvada)

   - Make the Intel quark_dts thermal driver Use generic trip point
     objects instead of its own trip point representation (Daniel
     Lezcano)

   - Add toctree entry for thermal documents and fix two issues in the
     Intel powerclamp driver documentation (Bagas Sanjaya)

   - Use strscpy() to instead of strncpy() in the thermal core (Xu
     Panda)

   - Fix thermal_sampling_exit() (Vincent Guittot)

   - Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam
     Chihi)

   - Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
     Uytterhoeven)

   - Fix useless call to set_trips() when resuming in the rcar_gen3
     thermal control driver and add interrupt support detection at init
     time to it (Niklas Söderlund)

   - Fix memory corruption in the hi3660 thermal driver (Yongqin Liu)

     (Vibhav Pant)

Pull RCU updates from Paul McKenney:

 - Documentation updates

 - Miscellaneous fixes, perhaps most notably:

      - Throttling callback invocation based on the number of callbacks
        that are now ready to invoke instead of on the total number of
        callbacks

      - Several patches that suppress false-positive boot-time
        diagnostics, for example, due to lockdep not yet being
        initialized

      - Make expedited RCU CPU stall warnings dump stacks of any tasks
        that are blocking the stalled grace period. (Normal RCU CPU
        stall warnings have done this for many years)

      - Lazy-callback fixes to avoid delays during boot, suspend, and
        resume. (Note that lazy callbacks must be explicitly enabled, so
        this should not (yet) affect production use cases)

 - Make kfree_rcu() and friends take advantage of polled grace periods,
   thus reducing memory footprint by almost two orders of magnitude,
   admittedly on a microbenchmark

   This also begins the transition from kfree_rcu(p) to
   kfree_rcu_mightsleep(p). This transition was motivated by bugs where
   kfree_rcu(p), which can block, was typed instead of the intended
   kfree_rcu(p, rh)

 - SRCU updates, perhaps most notably fixing a bug that causes SRCU to
   fail when booted on a system with a non-zero boot CPU. This
   surprising situation actually happens for kdump kernels on the
   powerpc architecture

   This also adds an srcu_down_read() and srcu_up_read(), which act like
   srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side
   critical section to be handed off from one task to another

 - Clean up the now-useless SRCU Kconfig option

   There are a few more commits that are not yet acked or pulled into
   maintainer trees, and these will be in a pull request for a later
   merge window

 - RCU-tasks updates, perhaps most notably these fixes:

      - A strange interaction between PID-namespace unshare and the
        RCU-tasks grace period that results in a low-probability but
        very real hang

      - A race between an RCU tasks rude grace period on a single-CPU
        system and CPU-hotplug addition of the second CPU that can
        result in a too-short grace period

      - A race between shrinking RCU tasks down to a single callback
        list and queuing a new callback to some other CPU, but where
        that queuing is delayed for more than an RCU grace period. This
        can result in that callback being stranded on the non-boot CPU

 - Torture-test updates and fixes

 - Torture-test scripting updates and fixes

 - Provide additional RCU CPU stall-warning information in kernels built
   with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute
   timeout limit for expedited RCU CPU stall warnings

  cgroup/cpuset: no need to explicitly init a global static variable

Pull workqueue updates from Tejun Heo:

 - When per-cpu workqueue workers expire after sitting idle for too
   long, they used to wake up to the CPU that they're bound to in order
   to exit. This unfortunately could cause unwanted disturbances on CPUs
   isolated for e.g. RT applications.

   The worker exit path is restructured so that an existing worker is
   unbound from its CPU before being woken up for the last time,
   allowing it to migrate away from an isolated CPU for exiting.

 - A couple debug improvements. Watchdog dump is made more compact and
   workqueue now warns if used-after-free during the RCU grace period
   after destroy_workqueue().

Pull irq updates from Thomas Gleixner:
 "Updates for the interrupt subsystem:

  Core:

   - Move the interrupt affinity spreading mechanism into lib/group_cpus
     so it can be used for similar spreading requirements, e.g. in the
     block multi-queue code

     This also contains a first usecase in the block multi-queue code
     which Jens asked to take along with the librarization

   - Improve irqdomain locking to close a number race conditions which
     can be observed with massive parallel device driver probing

   - Enforce and document the semantics of disable_irq() which cannot be
     invoked safely from non-sleepable context

   - Move the IPI multiplexing code from the Apple AIC driver into the
     core, so it can be reused by RISCV

  Drivers:

   - Plug OF node refcounting leaks in various drivers

   - Correctly mark level triggered interrupts in the Broadcom L2
     drivers

   - The usual small fixes and improvements

Pull timer updates from Thomas Gleixner:
 "Updates for timekeeping, timers and clockevent/source drivers:

  Core:

   - Yet another round of improvements to make the clocksource watchdog
     more robust:

       - Relax the clocksource-watchdog skew criteria to match the NTP
         criteria.

       - Temporarily skip the watchdog when high memory latencies are
         detected which can lead to false-positives.

       - Provide an option to enable TSC skew detection even on systems
         where TSC is marked as reliable.

     Sigh!

   - Initialize the restart block in the nanosleep syscalls to be
     directed to the no restart function instead of doing a partial
     setup on entry.

     This prevents an erroneous restart_syscall() invocation from
     corrupting user space data. While such a situation is clearly a
     user space bug, preventing this is a correctness issue and caters
     to the least suprise principle.

   - Ignore the hrtimer slack for realtime tasks in schedule_hrtimeout()
     to align it with the nanosleep semantics.

  Drivers:

   - The obligatory new driver bindings for Mediatek, Rockchip and
     RISC-V variants.

   - Add support for the C3STOP misfeature to the RISC-V timer to handle
     the case where the timer stops in deeper idle state.

   - Set up a static key in the RISC-V timer correctly before first use.

   - The usual small improvements and fixes all over the place"

Pull SoC DT updates from Arnd Bergmann:
 "About a quarter of the changes are for 32-bit arm, mostly filling in
  device support for existing machines and adding minor cleanups, mostly
  for Qualcomm and Samsung based machines.

  Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from
  Rockchips that have been around for a while but were lacking kernel
  support so far: RV1126 is a Vision SoC with an NPU and is used in the
  Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design
  for TV boxes and so far only comes with a dts for its refernece
  design.

  The other 32-bit boards that were added are two ASpeed AST2600 based
  BMC boards, the Microchip sam9x60_curiosity development board (Armv5
  based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards
  for i.MX53 and i.MX6ULL.

  On the RISC-V side, there are fewer patches, but a total of ten new
  single-board computers based on variations of the Allwinner D1/T113
  chip, plus one more board based on Microchip Polarfire.

  As usual, arm64 has by far the most changes here, with over 700
  non-merge changesets, among them over 400 alone for Qualcomm. The
  newly added SoCs this time are all recent high-end embedded SoCs for
  various markets, each on comes with support for its reference board:

   - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones
   - Qualcomm QDU1000/QRU1000 5G RAN platform
   - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs
   - TI J784S4 for industrial and automotive applications

  In total, there are 46 new arm64 machines:
   - Reference platforms for each of the five new SoCs
   - Three Amlogic based development boards
   - Six embedded machines based on NXP i.MX8MM and i.MX8MP
   - The Mediatek mt7986a based Banana Pi R3 router
   - Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115
     (Snapdragon 662) and SM8250 (Snapdragon 865)
   - Two LTE dongles, also based on MSM8916
   - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610),
     SDM450 and SDM632
   - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c)
   - Nine development boards based on Rockchips RK3588, RK3568, RK3566
     and RK3328.
   - Five development machines based on TI K3 (AM642/AM654/AM68/AM69)

  I have sorted the files according to the changes to Kconfig files,
  to make it easier to check what has changed compared to the 'make
  savedefconfig' output.

  The most notable change this time is a series from Mark Brown to add
  a 'virtconfig' target for arm64, which is for the moment the same as
  the 'defconfig' target but disables all the top-level SoC specific
  options in order to have a smaller and faster kernel build"

 "Unused boardfile removal for 6.3

  This is a follow-up to the deprecation of most of the old-style board
  files that was merged in linux-6.0, removing them for good.

  This branch is almost exclusively dead code removal based on those
  annotations. Some device driver removals went through separate
  subsystem trees, but the majority is in the same branch, in order to
  better handle dependencies between the patches and avoid breaking
  bisection.

  Unfortunately that leads to merge conflicts against other changes in
  the subsystem trees, but they should all be trivial to resolve by
  removing the files.

  See commit 7d0d3fa7 ("Merge tag 'arm-boardfiles-6.0' of
  git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
  description of which machines were marked unused and are now removed.

  The only removals that got postponed are Terastation WXL (mv78xx0) and
  Jornada720 (StrongARM1100), which turned out to still have potential
  users"
