Commit 32d4fd57 ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE")
uses raw_local_irq_enable/local_irq_disable() around call to
__intel_idle() in intel_idle_irq().

With interrupt enabled, timer tick interrupt can happen and a
subsequently call to __do_softirq() may change the lockdep hardirqs state
of a debug kernel back to 'on'. This will result in a mismatch between
the cpu hardirqs state (off) and the lockdep hardirqs state (on) causing
a number of false positive "WARNING: suspicious RCU usage" splats.

Fix that by using local_irq_disable() to disable interrupt in
intel_idle_irq().

Pull RCU fix from Paul McKenney:
 "This contains a pair of commits that fix 282d8998 ("srcu: Prevent
  expedited GPs and blocking readers from consuming CPU"), which was
  itself a fix to an SRCU expedited grace-period problem that could
  prevent kernel live patching (KLP) from completing.

  That SRCU fix for KLP introduced large (as in minutes) boot-time
  delays to embedded Linux kernels running on qemu/KVM. These delays
  were due to the emulation of certain MMIO operations controlling
  memory layout, which were emulated with one expedited grace period per
  access. Common configurations required thousands of boot-time MMIO
  accesses, and thus thousands of boot-time expedited SRCU grace
  periods.

  In these configurations, the occasional sleeps that allowed KLP to
  proceed caused excessive boot delays. These commits preserve enough
  sleeps to permit KLP to proceed, but few enough that the virtual
  embedded kernels still boot reasonably quickly.

  This represents a regression introduced in the v5.19 merge window, and
  the bug is causing significant inconvenience"

Sudip reports that alpha doesn't build properly, with errors like

  include/asm-generic/tlb.h:401:1: error: redefinition of 'tlb_update_vma_flags'
    401 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma)

  include/asm-generic/tlb.h:372:1: note: previous definition of 'tlb_update_vma_flags' with type 'void(struct mmu_gather *, struct vm_area_struct *)'
    372 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma) { }

the cause being that We have this odd situation where some architectures
were never converted to the newer TLB flushing interfaces that have a
range for the flush.  Instead people left them alone, and we have them
select the MMU_GATHER_NO_RANGE config option to make the tlb header
files account for this.

Peter Zijlstra cleaned some of these nasty header file games up in
commits

  1e9fdf21 ("mmu_gather: Remove per arch tlb_{start,end}_vma()")
  18ba064e ("mmu_gather: Let there be one tlb_{start,end}_vma() implementation")

but tlb_update_vma_flags() was left alone, and then commit b67fbebd
("mmu_gather: Force tlb-flush VM_PFNMAP vmas") ended up removing only
_one_ of the two stale duplicate dummy inline functions.

This removes the other stale one.

Somebody braver than me should try to remove MMU_GATHER_NO_RANGE
entirely, but it requires fixing up the oddball architectures that use
it: alpha, m68k, microblaze, nios2 and openrisc.

The fixups should be fairly straightforward ("fix the build errors it
exposes by adding the appropriate range arguments"), but the reason this
wasn't done in the first place is that so few people end up working on
those architectures.  But it could be done one architecture at a time,
hint, hint.

When trying to load modules built for RISC-V which include assembly files
the kernel loader errors with "unexpected relocation type 'R_RISCV_ALIGN'"
due to R_RISCV_ALIGN relocations being generated by the assembler.

The R_RISCV_ALIGN relocations can be removed at the expense of code space
by adding -mno-relax to gcc and as.  In commit 7a8e7da4
("RISC-V: Fixes to module loading") -mno-relax is added to the build
variable KBUILD_CFLAGS_MODULE. See [1] for more info.

The issue is that when kbuild builds a .S file, it invokes gcc with
the -mno-relax flag, but this is not being passed through to the
assembler. Adding -Wa,-mno-relax to KBUILD_AFLAGS_MODULE ensures that
the assembler is invoked correctly. This may have now been fixed in
gcc[2] and this addition should not stop newer gcc and as from working.

Jann reported a race between munmap() and unmap_mapping_range(), where
unmap_mapping_range() will no-op once unmap_vmas() has unlinked the
VMA; however munmap() will not yet have invalidated the TLBs.

Therefore unmap_mapping_range() will complete while there are still
(stale) TLB entries for the specified range.

Mitigate this by force flushing TLBs for VM_PFNMAP ranges.

Scattered across the archs are 3 basic forms of tlb_{start,end}_vma().
Provide two new MMU_GATHER_knobs to enumerate them and remove the per
arch tlb_{start,end}_vma() implementations.

 - MMU_GATHER_NO_FLUSH_CACHE indicates the arch has flush_cache_range()
   but does *NOT* want to call it for each VMA.

 - MMU_GATHER_MERGE_VMAS indicates the arch wants to merge the
   invalidate across multiple VMAs if possible.

With these it is possible to capture the three forms:

  1) empty stubs;
     select MMU_GATHER_NO_FLUSH_CACHE and MMU_GATHER_MERGE_VMAS

  2) start: flush_cache_range(), end: empty;
     select MMU_GATHER_MERGE_VMAS

  3) start: flush_cache_range(), end: flush_tlb_range();
     default

Obviously, if the architecture does not have flush_cache_range() then
it also doesn't need to select MMU_GATHER_NO_FLUSH_CACHE.

makes the signal to work as a DMA transfer request signal and

are masked.

PIO fallback does not work as interrupt signal is disabled.

Tasks the are being deboosted from SCHED_DEADLINE might enter
enqueue_task_dl() one last time and hit an erroneous BUG_ON condition:
since they are not boosted anymore, the if (is_dl_boosted()) branch is
not taken, but the else if (!dl_prio) is and inside this one we
BUG_ON(!is_dl_boosted), which is of course false (BUG_ON triggered)
otherwise we had entered the if branch above. Long story short, the
current condition doesn't make sense and always leads to triggering of a
BUG.

Fix this by only checking enqueue flags, properly: ENQUEUE_REPLENISH has
to be present, but additional flags are not a problem.

Fixes: 64be6f1f ("sched/deadline: Don't replenish from a !SCHED_DEADLINE entity")

Protect the struct amdgpu_bo_list with a mutex. This is used during command
submission in order to avoid buffer object corruption as recorded in
the link below.

v2 (chk): Keep the mutex looked for the whole CS to avoid using the
	  list from multiple CS threads at the same time.
