Subject: PPC: KVM: Disable mmu notifier check
|
|
|
|
When using hugetlbfs (which is required for HV mode KVM on 970), we
|
|
check for MMU notifiers that on 970 can not be implemented properly.
|
|
|
|
So disable the check for mmu notifiers on PowerPC guests, making
|
|
KVM guests work there, even if possibly racy in some odd circumstances.
