Subject: [RESEND PATCH V2 0/5] Fixups to work with crash tool
Date:   Mon, 25 Jul 2022 09:45:34 +0800
Message-Id: <20220725014539.1037627-1-xianting.tian@linux.alibaba.com>
Precedence: bulk

I ever sent the patch 1 in the link:
https://patchwork.kernel.org/project/linux-riscv/patch/20220708073150.352830-3-xianting.tian@linux.alibaba.com/
And patch 2,3 in the link:
https://patchwork.kernel.org/project/linux-riscv/patch/20220714113300.367854-2-xianting.tian@linux.alibaba.com/
https://patchwork.kernel.org/project/linux-riscv/patch/20220714113300.367854-3-xianting.tian@linux.alibaba.com/

This patch series just put these patches together, and with two new patch 4, 5.
these five patches are the fixups for machine_kexec, kernel mode PC for vmcore
and improvements for vmcoreinfo and memory layout dump.

The main changes in the five patchs as below,
Patch 1: use __smp_processor_id() instead of smp_processor_id() to cleanup
	 the console prints.
Patch 2: Add VM layout, va bits, ram base to vmcoreinfo, which can simplify
	 the development of crash tool as ARM64 already did
	 (arch/arm64/kernel/crash_core.c).
Patch 3: Add modules to virtual kernel memory layout dump.
Patch 4: Fixup to get correct kernel mode PC for vmcore.
Patch 5: Updates vmcoreinfo.rst.

With these 5 patches(patch 2 is must), crash tool can work well to analyze
a vmcore. The patches for crash tool for RISCV64 is in the link:
https://lore.kernel.org/linux-riscv/20220718025346.411758-1-xianting.tian@linux.alibaba.com/

Changes v1 -> v2:
 1, remove the patch "Add a fast call path of crash_kexec()" from this series
 of patches, as it already applied to riscv git.
 https://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git/commit/?h=for-next&id=3f1901110a89b0e2e13adb2ac8d1a7102879ea98
 2, add 'Reviewed-by' based on the comments of v1.  

Xianting Tian (5):
  RISC-V: use __smp_processor_id() instead of smp_processor_id()
  RISC-V: Add arch_crash_save_vmcoreinfo support
  riscv: Add modules to virtual kernel memory layout dump
  RISC-V: Fixup getting correct current pc
  riscv64: crash_core: Export kernel vm layout, phys_ram_base
