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>
