The first patch(1/2) is to add VM layout to vmcoreinfo, which can simlify the development of crash tool as ARM64 already did (arch/arm64/kernel/crash_core.c). The second patch(2/2) is to add MODULES to memory layout dump. Changes v1 -> v2: patch 1: add VA_BITS to vmcoreinfo as ARM64 does, not satp_mode. crash tool can read VA_BITS to determin the pagetable levels. patch 1,2: As MODULES area is only defined when CONFIG_64BIT=y for riscv64, so only use MODULES area when CONFIG_64BIT=y. Changes v2 -> v3: patch 1,2: use "#ifdef CONFIG_64BIT" instead of "IS_ENABLED(CONFIG_64BIT)" when check whether MODULES area is available.
