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" * tag 'ioremap-5.5' of git://git.infradead.org/users/hch/ioremap: (21 commits) nds32: use generic ioremap csky: use generic ioremap csky: remove ioremap_cache riscv: use the generic ioremap code lib: provide a simple generic ioremap implementation sh: remove __iounmap nios2: remove __iounmap hexagon: remove __iounmap m68k: rename __iounmap and mark it static arch: rely on asm-generic/io.h for default ioremap_* definitions asm-generic: don't provide ioremap for CONFIG_MMU asm-generic: ioremap_uc should behave the same with and without MMU xtensa: clean up ioremap x86: Clean up ioremap() parisc: remove __ioremap nios2: remove __ioremap alpha: remove the unused __ioremap wrapper hexagon: clean up ioremap ia64: rename ioremap_nocache to ioremap_uc unicore32: remove ioremap_cached ...
