  farm (testing is ongoing). In any case, it's worth fixing.

  Other than that, we've toned down an over-zealous VM_BUG_ON() and
  fixed ftrace stack unwinding in a bunch of cases.

  Summary:

   - Evaluate uaccess macro arguments outside of the critical section

   - Tighten up VM_BUG_ON() in pmd_populate_kernel() to avoid false positive

   - Fix ftrace stack unwinding using HAVE_FUNCTION_GRAPH_RET_ADDR_PTR"

[BUG]
Fstests generic/027 is pretty easy to trigger a slow but steady memory
leak if run with "-o compress=lzo" mount option.

Normally one single run of generic/027 is enough to eat up at least 4G ram.

[CAUSE]
In commit d4088803 ("btrfs: subpage: make lzo_compress_pages()
compatible") we changed how @page_in is released.

But that refactoring makes @page_in only released after all pages being
compressed.

This leaves error path not releasing @page_in. And by "error path"
things like incompressible data will also be treated as an error
(-E2BIG).

Thus it can cause a memory leak if even nothing wrong happened.

[FIX]
Add check under @out label to release @page_in when needed, so when we
hit any error, the input page is properly released.

Pull folio fixes from Matthew Wilcox:
 "In the course of preparing the folio changes for iomap for next merge
  window, we discovered some problems that would be nice to address now:

   - Renaming multi-page folios to large folios.

     mapping_multi_page_folio_support() is just a little too long, so we
     settled on mapping_large_folio_support(). That meant renaming, eg
     folio_test_multi() to folio_test_large().

     Rename AS_THP_SUPPORT to match

   - I hadn't included folio wrappers for zero_user_segments(), etc.
     Also, multi-page^W^W large folio support is now independent of
     CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need
     to fall back to the out-of-line zero_user_segments().

     Remove FS_THP_SUPPORT to match

   - The build bots finally got round to telling me that I missed a
     couple of architectures when adding flush_dcache_folio(). Christoph
     suggested that we just add linux/cacheflush.h and not rely on
     asm-generic/cacheflush.h"

If xnack is on, VM retry fault interrupt send to IH ring1, and ring1
will be full quickly. IH cannot receive other interrupts, this causes
deadlock if migrating buffer using sdma and waiting for sdma done
while handling retry fault.

Remove VMC from IH storm client, enable ring1 write pointer
overflow, then IH will drop retry fault interrupts and be able to receive
other interrupts while driver is handling retry fault.

IH ring1 write pointer doesn't writeback to memory by IH, and ring1
write pointer recorded by self-irq is not updated, so always read
the latest ring1 write pointer from register.

unmap range always increase atomic svms->drain_pagefaults to simplify
both parent range and child range unmap, page fault handle ignores the
retry fault if svms->drain_pagefaults is set to speed up interrupt
handling. svm_range_drain_retry_fault restart draining if another
range unmap from cpu.

kfd_process_wq_release drain retry fault to ensure no retry fault comes
after removing kfd process from the hash table, otherwise svm page fault
handler will fail to recover the fault and dump GPU vm fault log.

Refactor deferred list work to get_task_mm and take mmap write lock
to handle all ranges, and avoid mm is gone while inserting mmu notifier.
