Subject: [PATCH 10/13] rasdaemon: make sure the error is valid before handling
|
||
|
|
ranks
|
||
|
|
|
||
|
|
Fix "rank" handling according to the Bit 63 description in Intel SDM Vol.3C
|
||
|
|
Table 16-23, that says "... Use this information only after there is valid
|
||
|
|
first error info indicated by bit 62".
|
||
|
|
Also fix invalid comparisons of unsigned variables "rank0" and "rank1".
