The main one is a fix to the way in which we evaluate the macro
arguments to our uaccess routines, which we _think_ might be the root
cause behind some unkillable tasks we've seen in the Android arm64 CI
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:

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

[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 d4088803f5 ("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

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

[Why]
A warning appears in the log on GPU reset for
link_enc_cfg_link_encs_assign for the following condition:
ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false);
This is not expected behavior and may result in link encoders being
incorrectly assigned.
[How]
The dc->current_state is backed up into dm->cached_dc_state before
we commit 0 streams.
DC will clear link encoder assignments on the real state but the
changes won't propagate over to the copy we made before the
0 streams commit.
DC expects that link encoder assignments are *not* valid
when committing a state, so as a workaround it needs to be cleared
before passing it back into DC.
