[PATCH v2 0/4] MIPS: Modify mem= and memmap= parameter

[Tiezhu Yang <yangtiezhu@loongson.cn>]

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.

For kdump on MIPS, if the users want to limit the memory region for the
capture kernel to avoid corrupting the memory image of the panic kernel,
use the parameter memmap=limit@base is the proper way, I will submit a
patch to use memmap=limit@base for kexec-tools after this patchset is
applied.

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

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