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.
Xianting Tian (2): RISC-V: Add arch_crash_save_vmcoreinfo support riscv: Add modules to virtual kernel memory layout dump
