#     Merge tag 'ioremap-5.5' of git://git.infradead.org/users/hch/ioremap
#     
#     Pull generic ioremap support from Christoph Hellwig:
#      "This adds the remaining bits for an entirely generic ioremap and
#       iounmap to lib/ioremap.c. To facilitate that, it cleans up the giant
#       mess of weird ioremap variants we had with no users outside the arch
#       code.
#     
#       For now just the three newest ports use the code, but there is more
#       than a handful others that can be converted without too much work.
#     
#       Summary:
#     
#        - clean up various obsolete ioremap and iounmap variants
#     
#        - add a new generic ioremap implementation and switch csky, nds32 and
#          riscv over to it"
#
