KVM: PPC: Add cache flush on page map
When we map a page that wasn't icache cleared before, do so when first mapping it in KVM using the same information bits as the Linux mapping logic. That way we are 100% sure that any page we map does not have stale entries in the icache. Signed-off-by: Alexander Graf <agraf@suse.de>
