OEMNMIHandler (Compact 2013)
This function enables a nonmaskable interrupt (NMI) to be captured by an OEM.
OEMs implement this function if they are targeting an x86 platform.
This function is designed to handle critical power issues only. All critical power issues must be resolved by this function before returning to the kernel.
After this function returns to the kernel, the system halts.
For a sample implementation of this function, see the CEPC platform source code in Fwpc.c.
