Merge tag 'asm-generic-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic updates from Arnd Bergmann:
"These are cleanups for architecture specific header files:

- the comments in include/linux/syscalls.h have gone out of sync and
are really pointless, so these get removed

- The asm/bitsperlong.h header no longer needs to be architecture
specific on modern compilers, so use a generic version for newer
architectures that use new enough userspace compilers

- A cleanup for virt_to_pfn/virt_to_bus to have proper type checking,
forcing the use of pointers"
