a2d98feb4b drm/i915/psr: Do not wait for PSR being idle on on Panel Replay
We do not have ALPM on DP Panel Replay. Due to this SRD_STATUS[SRD State]
doesn't change from SRDENT_ON after Panel Replay is enabled until it gets
disabled.

On eDP Panel Replay DEEP_SLEEP is not reached.
_psr2_ready_for_pipe_update_locked is waiting DEEP_SLEEP bit getting reset.

Take these into account in Panel Replay code by not waiting PSR getting
idle after enabling VBI.

a436c77ea2 Three cleanups
- Drop stale exynos file pattern from MAINTAINERS file
   The old "exynos" directory is removed from MAINTAINERS as Samsung Exynos display bindings have been relocated. This resolves a warning from get_maintainers.pl about no files matching the outdated directory.
 
 - Constify struct exynos_drm_ipp_funcs
   By making struct exynos_drm_ipp_funcs constant, the patch enhances security by moving the structure to a read-only section of memory. This change results in a slight reduction in the data section size.
 
 - Remove unnecessary code
   The function exynos_atomic_commit is removed as it became redundant after a previous update. This cleans up the code and eliminates unused function declarations.
 
 One fixup
 - Fix wrong assignment in gsc_bind()
   A double assignment in gsc_bind() was flagged by the cocci tool and corrected to fix an incorrect assignment, addressing a potential issue introduced in a prior commit.

d1f2d51b71 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.

9d4c304001 KVM: x86: don't fall through case statements without annotations
clang warns on this because it has an unannotated fall-through between
cases:

   arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

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.

Fixes: d30d9ee94c ("KVM: x86: Only advertise KVM_CAP_READONLY_MEM when supported by VM")

890daedec4 RISC-V Fixes for 6.11-rc7
* 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.

8654fa5ca3 pwm: Fix an off-by-one in the stm32 driver
Hardware engineers tend to start counting at 1 while the software guys
 usually start with 0. This isn't so nice because that results in drivers
 where pwm device #2 needs to use the hardware registers with index 3.
 
 With the commits
 
 	796b942f65 ("mfd: stm32-timers: Add some register definitions with a parameter")
 	7cea05ae1d ("pwm-stm32: Make use of parametrised register definitions")
 
 (merged for v6.11-rc1) I tried to improve the situation and make this
 counting mismatch more explicit and transparent. However in one instance
 I failed to add the needed +1.
 
 This was noticed by Fabrice Gasnier (however in a way that made me
 hesitate to add a "Reported-by:" tag, see
 https://lore.kernel.org/linux-pwm/3515a8f3-436e-4d14-9bac-dfe6aa869819@foss.st.com),
 thanks to him for catching the issue.
 
 A small patch fixing that mismatch is the only change included here.

4e32c25b58 libfs: fix get_stashed_dentry()
get_stashed_dentry() tries to optimistically retrieve a stashed dentry
from a provided location.  It needs to ensure to hold rcu lock before it
dereference the stashed location to prevent UAF issues.  Use
rcu_dereference() instead of READ_ONCE() it's effectively equivalent
with some lockdep bells and whistles and it communicates clearly that
this expects rcu protection.
