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"
