Enables or disables the local machine check exception. This
is an extension of the MCA Recovery mechanism providing
the capability to deliver Uncorrected Recoverable (UCR)
Software Recoverable Action Required (SRAR) errors to
one or more specific logical processors threads receiving
previously poisoned or corrupted data. When enabled, the
UCR SRAR Machine Check Exception is delivered only to the
affected thread rather than broadcast to all threads in the

cases of multiple recoverable faults that are detected close,
which would otherwise result in a fatal machine check event.
The feature is available only on Advanced RAS processors.
This option is set to Disabled by default.
