Subject[PATCH 0/5] Fixups to work with crash tool
I ever sent the patch 1,2 in the link:
And patch 3,4 in the link:

This patch series just put these patches together, and with a new patch 5.
these five patches are the fixups for kexec, vmcore and improvements
for vmcoreinfo and memory layout dump.

The main changes in the five patchs as below,
Patch 1: Add a fast call path of crash_kexec() as other Arch(x86, arm64) do.
Patch 2: use __smp_processor_id() instead of smp_processor_id() to cleanup
the console prints.
Patch 3: Add VM layout, va bits, ram base to vmcoreinfo, which can simplify
the development of crash tool as ARM64 already did
Patch 4: Add modules to virtual kernel memory layout dump.
Patch 5: Fixup to get correct kernel mode PC for vmcore

With these 5 patches(patch 3 is must), crash tool can work well to analyze
a vmcore. The patches for crash tool for RISCV64 is in the link:

Xianting Tian (5):
RISC-V: Fixup fast call of crash_kexec()
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
