EDAC/mce_amd: Decode MCA_STATUS in bit definition order
Sort the MCA_STATUS bits in decode output to follow how they are defined in the register. The order is as follows: Bit | Decode ------------ 62 | Over 61 | UC 59 | MiscV 58 | AddrV 57 | PCC 55 | TCC 53 | SyndV 46 | CECC 45 | UECC 44 | Deferred 43 | Poison 40 | Scrub [ bp: Massage a bit. ] Signed-off-by: Yazen Ghannam <yazen.ghannam@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Cc: linux-edac <linux-edac@vger.kernel.org> Cc: x86@kernel.org Link: https://lkml.kernel.org/r/20190212212417.107049-2-Yazen.Ghannam@amd.com
