Hi all, At the suggestion of Boris, the first patch extends the mce_severity mechanism for handling UCNA/DEFERRED error. Link: https://lkml.org/lkml/2014/10/23/190
v2: The first patch have also eliminated a big hack to make mce_severity() work when called from non-exception context on the advice of Tony and Boris. Link: https://lkml.org/lkml/2014/10/27/1017 And on the basis of the first patch, the second patch adds the support for identifying and handling UCNA/DEFERRED error in machine_check_poll. V3: According to Boris, the second patch have also split `memory_error' from mem_deferred_error so that the memory_error() function can be used in other code paths separately. Link: https://lkml.org/lkml/2014/11/6/452 Boris also reported the warning about "MCI_STATUS_POISON" and "MCI_STATUS_POISON" redefined. V4: Like MCIP/RIPV/EIPV bits, MCI_STATUS_EN is specific to "machine check exception". As Tony suggested, the severity table entry for the "EN" check should have been skipped when calling from the CMCI/Poll handler.
