Pull fsverity fixes from Eric Biggers:

 - Fix a build error on parisc

 - Remove the non-large-folio-aware function fsverity_verify_page()

* tag 'fsverity-for-linus' of git://git.kernel.org/pub/scm/fs/fsverity/linux:
  fsverity: fix build error by adding fsverity_readahead() stub
  fsverity: remove fsverity_verify_page()
  f2fs: make f2fs_verify_cluster() partially large-folio-aware
  f2fs: remove unnecessary ClearPageUptodate in f2fs_verify_cluster()

This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

Most simple allocations use GFP_KERNEL, and with the new allocation
helpers being introduced, let's just take advantage of that to simplify
that default case.

It's a numbers game:

    git grep 'alloc_obj(' |
	sed 's/.*\(GFP_[_A-Z]*\).*/\1/' |
	sort | uniq -c | sort -n | tail

shows that about 90% of all those new allocator instances just use that
standard GFP_KERNEL.

Those helpers are already macros, and we can easily just make it be the
default case when the gfp argument is missing.

And yes, we could do that for all the legacy interfaces too, but let's
keep it to just the new ones at least for now, since those all got
converted recently anyway, so this is not any "extra" noise outside of
that limited conversion.

And, in fact, I want to do this before doing the -rc1 release, exactly
so that we don't get extra merge conflicts.

Commit 69050f8d6d07 ("treewide: Replace kmalloc with kmalloc_obj for
non-scalar types") started using the new allocation helpers, and in the
process showed that they were completely non-working.

The overflow logic in overflows_flex_counter_type() is completely the
wrong way around, and that broke __alloc_flex() completely.  By chance,
the resulting code was then such a mess that clang generated
sufficiently garbage code that objtool warned about it all.  Which made
it somewhat quicker to narrow things down.

While fixing overflows_flex_counter_type() would presumably fix this
all, I'm excising the whole broken overflow logic from __alloc_flex(),
because we don't want that kind of code in basic allocation functions
anyway.

That (no longer) broken overflows_flex_counter_type() thing needs to be
inserted into the actual __set_flex_counter() logic in the unlikely case
that we ever want this at all.  And made conditional.

Pull kmalloc_obj conversion from Kees Cook:
 "This does the tree-wide conversion to kmalloc_obj() and friends using
  coccinelle, with a subsequent small manual cleanup of whitespace
  alignment that coccinelle does not handle.

  This uncovered a clang bug in __builtin_counted_by_ref(), so the
  conversion is preceded by disabling that for current versions of
  clang.  The imminent clang 22.1 release has the fix.

  I've done allmodconfig build tests for x86_64, arm64, i386, and arm. I
  did defconfig builds for alpha, m68k, mips, parisc, powerpc, riscv,
  s390, sparc, sh, arc, csky, xtensa, hexagon, and openrisc"

Pull NTB (PCIe non-transparent bridge) updates from Jon Mason:
 "NTB updates include debugfs improvements, correctness fixes, cleanups,

  ntb_transport QP stats are converted to seq_file, a tx_memcpy_offload

  debugfs queue name truncation bug is corrected.

  Additional fixes address format specifier mismatches in ntb_tool and
  boundary conditions in the Switchtec driver, while unused MSI helpers
  are removed and the codebase migrates to dma_map_phys().

  Intel Gen6 (Diamond Rapids) NTB support is also added"

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Unfortunately, there is a corner case of __builtin_counted_by_ref()
usage that crashes[1] Clang since support was introduced in Clang 19.
Disable it prior to Clang 22. Found while tested kmalloc_obj treewide
refactoring (via kmalloc_flex() usage).
