Merge tag 'asm-generic-6.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic updates from Arnd Bergmann:
 "This is mainly set of cleanups of asm-generic/io.h, resolving problems
  with inconsistent semantics of ioread64/iowrite64 that were causing
  runtime and build issues.

  The "GENERIC_IOMAP" version that switches between inb()/outb() and
  readb()/writeb() style accessors is now only used on architectures
  that have PC-style ISA devices that are not memory mapped (x86, uml,
  m68k-q40 and powerpc-powernv), while alpha and parisc use a more
  complicated variant and everything else just maps the ioread
  interfaces to plan MMIO (readb/writeb etc).

  In addition there are two small changes from Raag Jadav to simplify
  the asm-generic/io.h indirect inclusions and from Jann Horn to fix a
  corner case with read_word_at_a_time"
