This patch series are the improvements for vmcoreinfo and memory
layout dump.
The first patch(1/2) is to add VM layout to vmcoreinfo, which can
simlify the development of crash tool as ARM64 already did
(arch/arm64/kernel/crash_core.c).
The second patch(2/2) is to add MODULES to memory layout dump.
Changes v1 -> v2:
patch 1: add VA_BITS to vmcoreinfo as ARM64 does, not satp_mode.
crash tool can read VA_BITS to determin the pagetable
levels.
patch 1,2: As MODULES area is only defined when CONFIG_64BIT=y for
riscv64, so only use MODULES area when CONFIG_64BIT=y.
Changes v2 -> v3:
patch 1,2: use "#ifdef CONFIG_64BIT" instead of "IS_ENABLED(CONFIG_64BIT)"
when check whether MODULES area is available.
Xianting Tian (2):
RISC-V: Add arch_crash_save_vmcoreinfo support
riscv: Add modules to virtual kernel memory layout dump
