Hi Vineet,
The EV_MachineCheck exception handler is halting the core for exceptions
which are not tlb_overlap_fault.
Since for the NPS platform each core is running a single thread in ZOL (Zero
Overhead Linux) isolation mode, we feel that most

I'm adding hot-plug support for the above arch and ran into performance issue
with execution of
partition_sched_domains () - About 0.5 sec per cpu, which is unacceptable with

It's a single chip with 4K cpus, capable of 400Gbps duplex. Evaluation board is
pizza box size.
