[PATCH 29/31] x86: MCE: Rename mce_notify_user to mce_notify_irq

[Andi Kleen]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Impact: cleanup

Rename the mce_notify_user function to mce_notify_irq. The next
patch will split the wakeup handling of interrupt context
and of process context and it's better to give it a clearer
name for this.

Contains a fix from Ying Huang
