Merge tag 'asm-generic-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic updates from Arnd Bergmann:
 "Just two small updates this time:

   - A series I did to unify the definition of PAGE_SIZE through
     Kconfig, intended to help with a vdso rework that needs the
     constant but cannot include the normal kernel headers when building
     the compat VDSO on arm64 and potentially others

   - a patch from Yan Zhao to remove the pfn_to_virt() definitions from
     a couple of architectures after finding they were both incorrect
     and entirely unused"

* tag 'asm-generic-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
  arch: define CONFIG_PAGE_SIZE_*KB on all architectures
  arch: simplify architecture specific page size configuration
  arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions
  mm: Remove broken pfn_to_virt() on arch csky/hexagon/openrisc
