ghes_edac_report_mem_error() in ghes_edac.c is a Long Method and have Duplicated Code with cper_mem_err_location(), cper_dimm_err_location(), and cper_mem_err_type_str() in drivers/firmware/efi/cper.c. 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 wrap up error status decoding logics and reuse it in cper_print_mem(). - Patch 02 is to introduces cper_*(), into ghes_edac_report_mem_error(), this can avoid bunch of duplicate code lines; Changes since v2: - delete the unified patch - adjust the order of patches - Link: https://lore.kernel.org/all/20211210134019.28536-1-xueshuai@xxxxxxxxxxxxxxxxx/ - Thanks Borislav Petkov for review comments. Changes since v1: - 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 - Link: https://lore.kernel.org/all/20211207031905.61906-2-xueshuai@xxxxxxxxxxxxxxxxx/ - Thanks Robert Richter for review comments.
