x86, mce: pass mce info to EDAC for decoding Move NB decoder along with required defines to EDAC MCE core. Add registration routines for further decoding of the MCE info in the AMD64 EDAC module. CC: Andi Kleen <andi@firstfloor.org> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

EDAC: move MCE error descriptions to EDAC core This is in preparation of adding AMD-specific MCE decoding functionality to the EDAC core. The error decoding macros originate from the AMD64 EDAC driver albeit in a simplified and cleaned up version here. While at it, add macros to generate the error description strings and use them in the error type decoders directly which removes a bunch of code and makes the decoding functions much more readable. Also, fix strings and shorten macro names. Remove superfluous htlink_msgs. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

amd64_edac: cleanup/complete NB MCE decoding * don't dump info which mcheck already does * update to newest BKDG * mv amd64_process_error_info -> amd64_decode_nb_mce * shorten error struct names * remove redundant info ptr in amd64_process_error_info * remove unused ErrorCodeExt[19:16] (MCx_STATUS) defines Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
