Merge tag 'asm-generic-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann: "This contains a series from Linus Walleij to unify the linux/io.h interface by making the ia64, alpha, parisc and sparc include asm-generic/io.h. All functions provided by the generic header are now available to all drivers, but the architectures can still override this. For the moment, mips and sh still don't include asm-generic/io.h but provide a full set of functions themselves. There are also a few minor cleanups unrelated to this" * tag 'asm-generic-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: alpha: add full ioread64/iowrite64 implementation parisc: Drop homebrewn io[read|write]64_[lo_hi|hi_lo] parisc: hide ioread64 declaration on 32-bit ia64: export memory_add_physaddr_to_nid to fix cxl build error asm-generic: Remove empty #ifdef SA_RESTORER parisc: Use the generic IO helpers parisc: Remove 64bit access on 32bit machines sparc: Fix the generic IO helpers alpha: Use generic <asm-generic/io.h>
