Kyle,

It depends on which camp the external customer that reported this
falls into:

1) "I'm OK disabling all soft offline requests".

or the:

2) "I'd like 4K pages to still go offline if the BIOS asks, just not any huge pages".

Shawn: Can you please find out?

-> Prefer the 2nd option, "4K pages still go offline if the BIOS asks, just not any huge pages."
