Subject: x86: Use the right register type when initializing x86 kvm processes.
X-Git-Tag: develop-gem5-snapshot~358

x86: Use the right register type when initializing x86 kvm processes.

Functionally this doesn't matter, since no bitfields are used in the
type and it devolves into just being a uint64_t, but we should use CR8
and not CR4 when initializing the CR8 register.
