Subject: [PATCH 0/4] Extract DEBUG_WX to shared use.
Some architectures support DEBUG_WX function, it's verbatim from each
others, so extract to mm/Kconfig.debug for shared use.
PPC and ARM ports don't support generic page dumper yet, so we only
refine x86 and arm64 port in this patch series.
For RISC-V port, the DEBUG_WX support depends on other patches which
be merged already:
- RISC-V page table dumper
- Support strict kernel memory permissions for security
Zong Li (4):
mm: add DEBUG_WX support
riscv: support DEBUG_WX
x86: mm: use ARCH_HAS_DEBUG_WX instead of arch defined
arm64: mm: use ARCH_HAS_DEBUG_WX instead of arch defined
