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
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.

Merge tag 'kmalloc_obj-treewide-v7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
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"

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
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 *".

mshv: Add debugfs to view hypervisor statistics
Introduce a debugfs interface to expose root and child partition stats when running with mshv_root.
Create a debugfs directory "mshv" containing 'stats' files organized by type and id. A stats file contains a number of counters depending on its type. e.g. an excerpt from a VP stats file:
TotalRunTime : 1997602722 HypervisorRunTime : 649671371 RemoteNodeRunTime : 0 NormalizedRunTime : 1997602721 IdealCpu : 0 HypercallsCount : 1708169 HypercallsTime : 111914774 PageInvalidationsCount : 0 PageInvalidationsTime : 0
On a root partition with some active child partitions, the entire directory structure may look like:
mshv/ stats # hypervisor stats lp/ # logical processors 0/ # LP id stats # LP 0 stats 1/ 2/ 3/ partition/ # partition stats 1/ # root partition id stats # root partition stats vp/ # root virtual processors 0/ # root VP id stats # root VP 0 stats 1/ 2/ 3/ 42/ # child partition id stats # child partition stats vp/ # child VPs 0/ # child VP id stats # child VP 0 stats 1/ 43/ 55/
On L1VH, some stats are not present as it does not own the hardware like the root partition does: - The hypervisor and lp stats are not present - L1VH's partition directory is named "self" because it can't get its own id - Some of L1VH's partition and VP stats fields are not populated, because it can't map its own HV_STATS_AREA_PARENT page.
