Re: [PATCH v3 0/4] riscv: Enable kexec handover and live update

[Chen Pei <cp0613@linux.alibaba.com>]

Hi Paul, could you review this series when you get a chance?

RISC-V needs no architecture-specific code for kexec handover: the
generic paths already work on riscv64, and what this series adds are the
enables. Patch 1 moves early_ioremap_setup() before parse_dtb(), the
order arm64 and x86 already use, because DT-based handover is the first
caller to map memory that early. Patch 2 adds
ARCH_SUPPORTS_KEXEC_HANDOVER. Patches 3 and 4 teach the KHO and live
update vmtest runners about riscv64.

The two prerequisites the series depends on are basically resolved: Greg
Thelen's fix to is_kho_boot() [1] is applied in the liveupdate fixes
tree, and Mike Rapoport's bootmem sizing series [2] is reviewed.
