CVE: NA

The original arm_event trace code only traces out ARM processor error
information data. It's not enough for user to take appropriate action.

According to UEFI_2_9 specification chapter N2.4.4, the ARM processor
error section includes several ARM processor error information, several
ARM processor context information and several vendor specific error
information structures. In addition to these info, there are error
severity and cpu logical index about the event. Report all of these
information to userspace via perf i/f. So that the user can do cpu core
isolation according to error severity and other info.
