In the current code, the kernel command-line parameter mem= and memmap=
can not work well on MIPS, this patchset refactors the related code to
fix them.

v5: Support mem=limit@base

v4: Fix some build warnings reported by kernel test robot

v3: Modify patch #3 to maintain compatibility for memmap=limit{$,#,!}base,
commented by Mike Rapoport, thank you

v2: Add some new patches to support memmap=limit@base

Tiezhu Yang (4):
memblock: Introduce memblock_mem_range_remove_map()
MIPS: Refactor early_parse_mem() to fix mem= parameter
MIPS: Refactor early_parse_memmap() to fix memmap= parameter
MIPS: Remove not used variable usermem
