From: Luo Haiyang <[email protected]>
This patchset fixes kexec-tool related to crashdump load on riscv
patch 1: crashload should use all system RAM but crash reserved memory.
patch 2: make the phys_to_virt function return the correct value.
patch 3: vmcore-dmesg accesses the address located in the bss segment,
use kernel image to creat kernel text elf header.
patch 4: due to the kernel image being additionally exported in /proc/iomem,
the kernel memory range is not correctly handled by to_be_excluded.
Changes from v2:
- use kernel image to creat kernel text elf header
- do not exclude kernel memory range
-
