Implement hooks called by generic KVM code.
Also add code that will copy the host's CPU and timebase frequencies to the
guest, which is necessary on KVM because the guest can directly access the
timebase.

deviation is huge. That suggests that the vast majority
of exits take the minimum amount of time, but a few exits take a *ton*
of time. Looking through the set of instructions we emulate on 440, it
looks like the only even slightly sophisticated ones are rfi, tlbwe, and
tlbsx...

This patch, which I'll call the direct TLB patch

Out of curiosity, if you had 4K Linux host pages, and you redefined
TARGET_PAGE_BITS to be 12, would everything just work?
Also, as long as I have you... can we use getpagesize() instead of 65536/4096
in qemu_vmalloc()?

kvm: ppc: Rename struct tlbe to struct kvmppc_44x_tlbe
This will ease ports to other cores.
Also remove
the index by offset or save index in vcpu-arch.
What's your opinion?
I would definitely prefer using the index as a return value, rather than
saving to vcpu-arch.

This will make it easier to provide implementations
not sure it's worth the development complexity.
I'll have to keep thinking about those other cores without directly
