Subject: [PATCH V3 0/2] Improve vmcoreinfo and memory layout dump
Date:   Thu, 14 Jul 2022 19:32:58 +0800
Message-Id: <20220714113300.367854-1-xianting.tian@linux.alibaba.com>
Precedence: bulk

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
