This patch set is a rework of the ghes_edac and edac_mc driver. It
addresses issues found during code review and while working with the
code. The changes include:

 * improve function interfaces and data structures to decrease
   complexity such as number of function arguments, unused data, etc.
   (#1, #2, #6, #10, #12, #13),

 * add helper functions and factor out code (#3, #8, #9, #14)

 * fix style issues found by checkpatch (#4)

 * improve code readability (#5, #7, #11)

 * use of standard kernel macros (#15)

 * code unification (#16, #17, #18)

 * documentation updates (#19)

This series contains some patches that have been posted and reviewed
earlier here:

 https://lore.kernel.org/patchwork/cover/1093488/

Review comments have been addressed and the following changes have
been made to those patches:

 * rebased onto ras:edac-for-next (v5.4-rc1 based)

 * reworded patch descriptions

 * dropped hunk that only reorders code in "EDAC, ghes: Remove
   pvt->detail_location string"

 * updated description for edac_get_dimm_by_index()

 * updated description for edac_get_dimm()

 * small style changes in "EDAC: Replace EDAC_DIMM_PTR() macro with
   edac_get_dimm() function"

 * use unsigned type for dimm->idx to avoid need for negative range
   check

 * fixed mci_for_each_dimm() loop in i5100_init_csrows()

 * fixed off-by-one in mci_for_each_dimm()

Sorry for the:

  Content-Transfer-Encoding: quoted-printable

I definitely sent it out 8bit, but thanks to office365 this was
converted (IMO this is according to RFC but still a pain).

I will switch to another account for sending patches in the future.

Thanks Mauro for your review of the whole series. I hope I could all
your concerns address with my answers.
