4bdc0d676a remove ioremap_nocache and devm_ioremap_nocache
ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

076863473c m68k: rename __iounmap and mark it static
m68k uses __iounmap as the name for an internal helper that is only
used for some CPU types.  Mark it static, give it a better name
and move it around a bit to avoid a forward declaration.

2cecd1f11c m68k: Simplify ioremap_nocache()
Just define ioremap_nocache to ioremap instead of duplicating the
inline.  Also define ioremap_uc in terms of ioremap instead of
using a double indirection.

ab4d391d27 m68k/io: Move mem*io define guards to <asm/kmap.h>
The mem*io define guards are applicable to all users of <asm/kmap.h>.
Hence move them, and drop the #ifdef.

e295066f66 m68k/io: Add missing ioremap define guards, fix typo
- Add missing define guard for ioremap_wt(),
  - Move ARCH_HAS_IOREMAP_WT from <asm/io_mm.h> to <asm/kmap.h>, as it
    is applicable to Coldfire with MMU, too,
  - Fix typo s/ioremap_fillcache/ioremap_fullcache/,
  - Add define guard for iounmap() for consistency with other
    architectures.

9746882f54 m68k: group io mapping definitions and functions
Create a new header file, kmap.h, that groups all the definitions and
functions associated with the io mapping and remapping.

Currently the functions are spread across raw_io.h and io_mm.h. And in
the future we will want to use these in io_no.h as well. So it makes
sense to move them all together into a single header file.

It is named after the arch/m68k/mm/kmap.c file that actually implements
many of the exported functions.
