#     Merge tag 'ioremap-5.6' of git://git.infradead.org/users/hch/ioremap
#     
#     Pull ioremap updates from Christoph Hellwig:
#      "Remove the ioremap_nocache API (plus wrappers) that are always
#       identical to ioremap"
#     
#     * tag 'ioremap-5.6' of git://git.infradead.org/users/hch/ioremap:
#       remove ioremap_nocache and devm_ioremap_nocache
#       MIPS: define ioremap_nocache to ioremap
