It turns out that for the CONFIG_MMU=n builds, vmalloc_huge() was never
defined, since it's defined in mm/vmalloc.c, which doesn't get built for
the no-MMU configurations.

Just implement the trivial wrapper for the no-MMU case too.  In fact,
just make it an alias to the existing __vmalloc() function that has the
same signature.

Since commit 559089e0 ("vmalloc: replace VM_NO_HUGE_VMAP with
VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc is an
opt-in strategy, because it caused a number of problems that weren't
noticed until x86 enabled it too.

One of the issues was fixed by Nick Piggin in commit 3b8000ae
("mm/vmalloc: huge vmalloc backing pages should be split rather than
compound"), but I'm still worried about page protection issues, and
VM_FLUSH_RESET_PERMS in particular.

However, like the hash table allocation case (commit f2edd118:
"page_alloc: use vmalloc_huge for large system hash"), the use of
kvmalloc() should be safe from any such games, since the returned
pointer might be a SLUB allocation, and as such no user should
reasonably be using it in any odd ways.

We also know that the allocations are fairly large, since it falls back
to the vmalloc case only when a kmalloc() fails.  So using a hugepage
mapping seems both safe and relevant.

This patch does show a weakness in the opt-in strategy: since the opt-in
flag is in the 'vm_flags', not the usual gfp_t allocation flags, very
few of the usual interfaces actually expose it.

That's not much of an issue in this case that already used one of the
fairly specialized low-level vmalloc interfaces for the allocation, but
for a lot of other vmalloc() users that might want to opt in, it's going
to be very inconvenient.

We'll either have to fix any compatibility problems, or expose it in the
gfp flags (__GFP_COMP would have made a lot of sense) to allow normal
vmalloc() users to use hugepage mappings.  That said, the cases that
really matter were probably already taken care of by the hash tabel
allocation.

Use vmalloc_huge() in alloc_large_system_hash() so that large system

Test case 71 'Convert perf time to TSC' is not supported on s390.

Subtest 71.1 is skipped with the correct message, but subtest 71.2 is
not skipped and fails.

The root cause is function evlist__open() called from
test__perf_time_to_tsc().  evlist__open() returns -ENOENT because the
event cycles:u is not supported by the selected PMU, for example
platform s390 on z/VM or an x86_64 virtual machine.

The PMU driver returns -ENOENT in this case. This error is leads to the
failure.

Fix this by returning TEST_SKIP on -ENOENT.

 71: Convert perf time to TSC:
 71.1: TSC support:             Skip (This architecture does not support)

Since commit bb30acae ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't report result if the PERF_SAMPLE_DATA_SRC bit is missed in sample
type.

The commit ffab4870 ("perf: arm-spe: Fix perf report
--mem-mode") partially fixes the issue.  It adds PERF_SAMPLE_DATA_SRC
bit for Arm SPE event, this allows the perf data file generated by
kernel v5.18-rc1 or later version can be reported properly.

On the other hand, perf tool still fails to be backward compatibility
for a data file recorded by an older version's perf which contains Arm
SPE trace data.  This patch is a workaround in reporting phase, when
detects ARM SPE PMU event and without PERF_SAMPLE_DATA_SRC bit, it will
force to set the bit in the sample type and give a warning info.

Commit 5467801f ("gpio: Restrict usage of GPIO chip irq members
before initialization") attempted to fix a race condition that lead to a
NULL pointer, but in the process caused a regression for _AEI/_EVT
declared GPIOs.

This manifests in messages showing deferred probing while trying to
allocate IRQs like so:

  amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517
  amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517
  amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517
  [ .. more of the same .. ]

The code for walking _AEI doesn't handle deferred probing and so this
leads to non-functional GPIO interrupts.

Fix this issue by moving the call to `acpi_gpiochip_request_interrupts`
to occur after gc->irc.initialized is set.

Pull mount_setattr fix from Christian Brauner:
 "The recent cleanup in e257039f ("mount_setattr(): clean the
  control flow and calling conventions") switched the mount attribute
  codepaths from do-while to for loops as they are more idiomatic when
  walking mounts.

  However, we did originally choose do-while constructs because if we
  request a mount or mount tree to be made read-only we need to hold
  writers in the following way: The mount attribute code will grab
  lock_mount_hash() and then call mnt_hold_writers() which will
  _unconditionally_ set MNT_WRITE_HOLD on the mount.

  Any callers that need write access have to call mnt_want_write(). They
  will immediately see that MNT_WRITE_HOLD is set on the mount and the
  caller will then either spin (on non-preempt-rt) or wait on
  lock_mount_hash() (on preempt-rt).

  The fact that MNT_WRITE_HOLD is set unconditionally means that once
  mnt_hold_writers() returns we need to _always_ pair it with
  mnt_unhold_writers() in both the failure and success paths.

  The do-while constructs did take care of this. But Al's change to a
  for loop in the failure path stops on the first mount we failed to
  change mount attributes _without_ going into the loop to call
  mnt_unhold_writers().

  This in turn means that once we failed to make a mount read-only via
  mount_setattr() - i.e. there are already writers on that mount - we
  will block any writers indefinitely. Fix this by ensuring that the for
  loop always unsets MNT_WRITE_HOLD including the first mount we failed
  to change to read-only. Also sprinkle a few comments into the cleanup
  code to remind people about what is happening including myself. After
  all, I didn't catch it during review.

  This is only relevant on mainline and was reported by syzbot. Details
  about the syzbot reports are all in the commit message"

There is a race between xas_split() and xas_load() which can result in
the wrong page being returned, and thus data corruption.  Fortunately,
it's hard to hit (syzbot took three months to find it) and often guarded
with VM_BUG_ON().

The anatomy of this race is:

thread A			thread B
order-9 page is stored at index 0x200
				lookup of page at index 0x274
page split starts
				load of sibling entry at offset 9
stores nodes at offsets 8-15
				load of entry at offset 8

The entry at offset 8 turns out to be a node, and so we descend into it,
and load the page at index 0x234 instead of 0x274.  This is hard to fix
on the split side; we could replace the entire node that contains the
order-9 page instead of replacing the eight entries.  Fixing it on
the lookup side is easier; just disallow sibling entries that point
to nodes.  This cannot ever be a useful thing as the descent would not
know the correct offset to use within the new node.

The test suite continues to pass, but I have not added a new test for
this bug.

Huge vmalloc higher-order backing pages were allocated with __GFP_COMP
in order to allow the sub-pages to be refcounted by callers such as
"remap_vmalloc_page [sic]" (remap_vmalloc_range).

However a similar problem exists for other struct page fields callers
use, for example fb_deferred_io_fault() takes a vmalloc'ed page and
not only refcounts it but uses ->lru, ->mapping, ->index.

This is not compatible with compound sub-pages, and can cause bad page
state issues like

  BUG: Bad page state in process swapper/0  pfn:00743

The correct approach is to use split high-order pages for the huge
vmalloc backing. These allow callers to treat them in exactly the same
way as individually-allocated order-0 pages.
