[PATCH V2 0/2] Improve vmcoreinfo and memory layout dump

[Xianting Tian <xianting.tian@linux.alibaba.com>]

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
