    x86/mce: Handle Local MCE events · 243d657e
    Ashok Raj 提交于
    Add the necessary changes to do_machine_check() to be able to
    process MCEs signaled as local MCEs. Typically, only recoverable
    errors (SRAR type) will be Signaled as LMCE. The architecture
    does not restrict to only those errors, however.
    
    When errors are signaled as LMCE, there is no need for the MCE
    handler to perform rendezvous with other logical processors
    unlike earlier processors that would broadcast machine check
    errors.
