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
