Subject: Documentation: kdump: Add va_kernel_pa_offset for RISCV64
From: Song Shuai <suagrfillet@xxxxxxxxx>
commit 640c503d7dbd7d34a62099c933f4db0ed77ccbec upstream.
RISC-V Linux exports "va_kernel_pa_offset" in vmcoreinfo to help
Crash-utility translate the kernel virtual address correctly.
Here adds the definition of "va_kernel_pa_offset".
Fixes: 3335068f8721 ("riscv: Use PUD/P4D/PGD pages for the linear mapping")
