[Why]

DC has a special commit path for native cursor, which use the built-in
cursor pipe within DCN planes. This update path does not require all
enabled planes to be added to the list of surface updates sent to DC.

This is not the case for overlay cursor; it uses the same path as MPO
commits. This update path requires all enabled planes to be added to the
list of surface updates sent to DC. Otherwise, DC will disable planes
not inside the list.

[How]

If overlay cursor is needed, add all planes on the same CRTC as this
cursor to the atomic state. This is already done for non-cursor planes
(MPO), just before the added lines.

[Why]

drm_normalize_zpos will set the crtc_state->zpos_changed to 1 if any of
it's assigned planes changes zpos, or is removed/added from it.

To have amdgpu_dm request a plane reset on this is too broad. For
example, if only the cursor plane was moved from one crtc to another,
the crtc's zpos_changed will be set to true. But that does not mean that
the underlying primary plane requires a reset.

[How]

Narrow it down so that only the plane that has a change in zpos will
require a reset.

As a future TODO, we can further optimize this by only requiring a reset
on z-order change. Z-order is different from z-pos, since a zpos change
doesn't necessarily mean the z-ordering changed, and DC should only
require a reset if the z-ordering changed.

For example, the following zpos update does not change z-ordering:

    Plane A: zpos 2 -> 3
    Plane B: zpos 1 -> 2
    => Plane A is still on top of plane B: no reset needed

Whereas this one does change z-ordering:

    Plane A: zpos 2 -> 1
    Plane B: zpos 1 -> 2
    => Plane A changed from on top, to below plane B: reset needed

dc_state_destruct() nulls the resource context of the DC state. The pipe
context passed to dcn35_set_drr() is a member of this resource context.

If dc_state_destruct() is called parallel to the IRQ processing (which
calls dcn35_set_drr() at some point), we can end up using already nulled
function callback fields of struct stream_resource.

The logic in dcn35_set_drr() already tries to avoid this, by checking tg
against NULL. But if the nulling happens exactly after the NULL check and
before the next access, then we get a race.

Avoid this by copying tg first to a local variable, and then use this
variable for all the operations. This should work, as long as nobody
frees the resource pool where the timing generators live.

init() was removed from ramgp102 when reworking the memory detection, as
it was thought that the code was only necessary when the driver performs
mclk changes, which nouveau doesn't support on pascal.

However, it turns out that we still need to execute this on some GPUs to
restore settings after DEVINIT, so revert to the original behaviour.

Until VM_DONTEXPAND was added in commit 1c1914d6 ("dma-buf: heaps:
Don't track CMA dma-buf pages under RssFile") it was possible to obtain
a mapping larger than the buffer size via mremap and bypass the overflow
check in dma_buf_mmap_internal. When using such a mapping to attempt to
fault past the end of the buffer, the CMA heap fault handler also checks
the fault offset against the buffer size, but gets the boundary wrong by
1. Fix the boundary check so that we don't read off the end of the pages
array and insert an arbitrary page in the mapping.

 "A pile of Qualcomm clk driver fixes with two main themes: the alpha
  PLL driver and shared RCGs, and one fix for the Starfive JH7110 SoC.

   - The Alpha PLL clk_ops had multiple problems around setting rates.

     There are a handful of patches here that fix masks and skip
     enabling the clk from set_rate() when the PLL is disabled. The PLLs
     are crucial to operation of the system as almost all frequencies in
     the system are derived from them.

   - Parking shared RCGs at a slow always on clk at registration time
     breaks stuff.

     USB host mode can't handle such a slow frequency and the serial
     console gets all garbled when the UART clk is handed over to the
     kernel. There's a few patches that don't use the shared clk_ops for
     the UART clks and another one to skip parking the USB clk at
     registration time.

   - The Starfive PLL driver used for the CPU was busted causing cpufreq
     to fail because the clk didn't change to a safe parent during
     set_rate().

     The fix is to register a notifier and switch to a safe parent so
     the PLL can change rate in a glitch free manner"

clang warns on this because it has an unannotated fall-through between
cases:

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break.  Odd.

  arm64: stacktrace: fix the usage of ftrace_graph_ret_addr()

Pull RISC-V fixes from Palmer Dabbelt:

 - A revert for the mmap() change that ties the allocation range to the
   hint adress, as what we tried to do ended up regressing on other
   userspace workloads.

 - A fix to avoid a kernel memory leak when emulating misaligned
   accesses from userspace.

 - A Kconfig fix for toolchain vector detection, which now correctly
   detects vector support on toolchains where the V extension depends on
   the M extension.

 - A fix to avoid failing the linear mapping bootmem bounds check on
   NOMMU systems.

 - A fix for early alternatives on relocatable kernels.

Pull powerpc fixes from Michael Ellerman:

 - Fix a deadlock in the powerpc qspinlock MCS queue logic

 - Fix the return type of pgd_val() to not truncate 64-bit PTEs on 85xx

 - Allow the check for dynamic relocations in the VDSO to work correctly

 - Make mmu_pte_psize static to fix a build error

Moolchandani, Jijo Varghese, and Vaishnavi Bhat.

Pull x86 kvm fixes from Paolo Bonzini:
 "Many small fixes that accumulated while I was on vacation...

   - Fixup missed comments from the REMOVED_SPTE => FROZEN_SPTE rename

   - Ensure a root is successfully loaded when pre-faulting SPTEs

   - Grab kvm->srcu when handling KVM_SET_VCPU_EVENTS to guard against
     accessing memslots if toggling SMM happens to force a VM-Exit

   - Emulate MSR_{FS,GS}_BASE on SVM even though interception is always
     disabled, so that KVM does the right thing if KVM's emulator
     encounters {RD,WR}MSR

   - Explicitly clear BUS_LOCK_DETECT from KVM's caps on AMD, as KVM
     doesn't yet virtualize BUS_LOCK_DETECT on AMD

   - Cleanup the help message for CONFIG_KVM_AMD_SEV, and call out that
     KVM now supports SEV-SNP too

   - Specialize return value of
     KVM_CHECK_EXTENSION(KVM_CAP_READONLY_MEM), based on VM type

   - Remove unnecessary dependency on CONFIG_HIGH_RES_TIMERS

   - Note an RCU quiescent state on guest exit. This avoids a call to
     rcu_core() if there was a grace period request while guest was
     running"

Pull sound fixes from Takashi Iwai:
 "Hopefully the last PR for 6.11, at least for this level of amount.

  In addition to the usual HD-audio quirks, there are more changes in
  ASoC, but all look small and device-specific fixes, and nothing stands
  out. The only slightly big change is sunxi I2S fix, which looks quite
  safe to apply, too"
