Subject: [PATCH v3 0/2] EDAC/ghes: refactor memory error reporting to avoid

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@linux.alibaba.com/
- 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@linux.alibaba.com/
- Thanks Robert Richter for review comments.
