H A D | mce.h | diff 63f44d65143976af9b28cf70ebe23f2c8b38677a Mon Apr 03 07:29:34 CEST 2017 Michael Ellerman <mpe@ellerman.id.au> powerpc/book3s: Print task info if we take a machine check in user mode
For an MCE (Machine Check Exception) that hits while in user mode MSR(PR=1), print the task info to the console MCE error log. This may help to identify an application that triggered the MCE.
After this patch the MCE console looks like:
Severe Machine check interrupt [Recovered] NIP: [0000000010039778] PID: 762 Comm: ebizzy Initiator: CPU Error type: SLB [Multihit] Effective address: 0000000010039778
