[PATCH 0/5] riscv: mm: init clean up #ifdefs

[Jisheng Zhang <jszhang@kernel.org>]

To support NOMMU, XIP, the arch/riscv/mm/init.c becomes much complex
due to lots of #ifdefs, this not only impacts the code readability,
compile coverage, but may also bring bug. For example, I believe one
recently fixed bug[1] is caused by this issue when merging.

This series tries to clean up unnecessary #ifdefs as much as possible.
Further cleanups may need to refactor the XIP code as Alexandre's patch
does.

Jisheng Zhang (5):
  riscv: mm: init: remove unnecessary "#ifdef CONFIG_CRASH_DUMP"
  riscv: mm: init: try IS_ENABLED(CONFIG_64BIT) instead of #ifdef
  riscv: mm: init: remove _pt_ops and use pt_ops directly
  riscv: mm: init: try IS_ENABLED(CONFIG_XIP_KERNEL) instead of #ifdef
  riscv: mm: init: try best to remove #ifdef CONFIG_XIP_KERNEL usage
