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,
so add bss segment to the kernel text elf.
Changes from v1:
