In addition, the cper_print_mem() in drivers/firmware/efi/cper.c only reports the error status and misses its description. This patch set is to refactor ghes_edac_report_mem_error with: - Patch 01 is to unify memory error report format with cper; - Patch 02 is to introduces cper_*(), into ghes_edac_report_mem_error(), this can avoid bunch of duplicate code lines; - Patch 02 is to wrap up error status decoding logics and reuse it in cper_print_mem(). Changes since v1: https://lore.kernel.org/all/20211207031905.61906-2-xueshuai@linux.alibaba.com/ - add a new patch to unify ghes and cper before removing duplication. - document the changes in patch description - add EXPORT_SYMBOL_GPL()s for cper_*() - document and the dependency and add UEFI_CPER dependency explicitly Thanks Robert Richter for review comments.
