Also add cpu number while displaying MCE log. This will help cleaner
logs when MCE hits on multiple cpus simultaneously.
Before the changes the MCE output was:
Severe Machine check interrupt [Recovered]
NIP [d00000000ba80280]: insert_slb_entry.constprop.0+0x278/0x2c0 [mcetest_slb]
Initiator: CPU
Error type: SLB [Multihit]
Effective address: d00000000ba80280
After this patch series changes the MCE output will be:
MCE: CPU80: machine check (Warning) Host SLB Multihit [Recovered]
MCE: CPU80: NIP: [d00000000b550280] insert_slb_entry.constprop.0+0x278/0x2c0 [mcetest_slb]
MCE: CPU80: Probable software error (some chance of hardware cause)
UE in host application:
