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
