this 1GB poisoned
hugetlbfs page. We have a plan to split this 1GB hugetblfs page by 2MB
hugetlbfs pages/4KB pages, maybe file remap to a virtual address range
which is 2MB/4KB page granularity, also split the KVM MMU 1GB SPTE
into 2MB/4KB and mark the offensive SPTE w/ a hwpoison flag, a sigbus
will be delivered to VM at page fault next time for the offensive
SPTE. Is this proposal acceptable?

How about replace "halt-polling" by "Adaptive halt-polling"? Btw,
thanks for your docs.
