32a92f8c89 Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

323bbfcf1e Convert 'alloc_flex' family to use the new default GFP_KERNEL argument
This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.

As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
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.

e19e1b480a add default_gfp() helper macro and use it in the new *alloc_obj() helpers
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.

fa5c82f4d2 slab.h: disable completely broken overflow handling in flex allocations
Commit 69050f8d6d ("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.

Fixes: 81cee9166a ("compiler_types: Introduce __flex_counter() and family")

9813616045 NTB updates include debugfs improvements, correctness fixes,
cleanups, and new hardware support. ntb_transport QP stats are
 converted to seq_file, a tx_memcpy_offload module parameter is
 introduced with associated ordering fixes, and a 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.

 - A fix for a missing URING_CMD128 opcode check, fixing an issue with
   the SQE mixed mode support introduced in 6.19. Merged late due to
   having multiple dependencies

 - Add sqe->cmd size checking for big SQEs, similar to what we have for
   normal sized SQEs

 - Fix a race condition in zcrx, that leads to a double free

817c16e565 memblock: numa_memblks: fix detection of NUMA node for CXL windows
phys_to_target_node() may assign a CXL Fixed Memory Window to the wrong NUMA
 node when a CXL node resides in the gap of discontinuous System RAM node.
 
 Fix this by checking both numa_meminfo and numa_reserved_meminfo, preferring
 the reserved NID when the address appears in both.
