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
