x86, mce: rename mce_notify_user to mce_notify_irq
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 [ Impact: cleanup ] Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Cc: Huang Ying <ying.huang@intel.com> Signed-off-by: H.
