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
(arch/arm64/kernel/crash_core.c).
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
Vmcoreinfo changes need to be documented in
Documentation/admin-guide/kdump/vmcoreinfo.rst
Otherwise, I suggest to always cc kexec mail list (added in cc) for
kexec | kdump patches.
thanks, I will fix it in v3.
