unsync_child_bitmap takes one cacheline; the shadow page table takes
64. This will make unsync/resync much more

in getting rid of number of die() calls we have in code.

If the guest programs an IPI with level=0 (de-assert) and trig_mode=0 (edge),
it is erroneously treated as INIT de-assert and ignored, but to quote the
spec: "For this delivery mode [INIT de-assert], the level flag must be set to
0 and trigger mode flag to 1."

If a guest's ram_size exceeds KVM_32BIT_GAP_START, the corresponding kvm tool's
virtual address size should be (ram_size + KVM_32BIT_GAP_SIZE), rather than
ram_size.
