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. Changes v2 -> v3: use "riscv" instead of "riscv64" in patch 5 subject line. Changes v3 -> v4: use "riscv" instead of "riscv64" in the summary of patch 5 subject line.
