kvm_write_guest would work, but it will hurt performance a bit because
it'll be doing the address translation each time the time is updated,
which happens on most guest enters.
Another possibility would be to change kvm_gfn_to_hva_cache_init to
accept a size parameter. If the requested range is a

Now that we have a CPU object with a reset method, it is better to
keep the KVM reset close to the CPU reset. Using qemu_register_reset
as we do now keeps them far apart.
As a side effect, a CPU reset (cpu_reset) will reset the KVM state too.

These patches finally implement INIT entirely in userspace. The problem
here was that the CPU was being reset after kvm_arch_reset_vcpu is called.
This made it harder to hook into the reset process and put APs into
KVM_MP_STATE_INIT_RECEIVED state (instead of KVM_MP_STATE_UNINITIALIZED
which is th
When an INIT comes in, we can do the entire reset process in userspace.
However, we have to be careful and move APs into KVM_MP_STATE_INIT_RECEIVED,
so that the in-kernel APIC will listen to startup IPIs.

Add one to esel values in h2g_tlb1_rmap, so that "no mapping" can be
distinguished from "esel 0". Note that we're not saved by the fact
that host esel 0 is reserved for non-KVM use, because KVM host esel
numbering is not the raw host numbering (see to_htlb1_esel).

It's possible that we're using the same host TLB1 slot to map (a
presumably different portion of) the same guest TLB1 entry. Clear
the bit in the map before setting it, so that if the esels are the same
the bit will remain set.
