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.
