Define the 32bit specific registers (SPSRs, cp15...).
Most CPU registers are directly mapped to a 64bit register
(r0->x0...). Only the SPSRs have separate registers.
cp15 registers are also mapped into their 64bit counterpart in most
cases.

Wire the init of a 32bit vcpu by allowing 32bit modes in pstate,
and providing sensible defaults out of reset state.
This feature is of course conditioned by the presence of 32bit
capability on the physical CPU, and is checked by the KVM_CAP_ARM_EL1_32BIT
capability.

Hello all,
Another lock up again this evening :( am wondering whether should consider
upgrading the kernel to 3.7.10 and the latest version of KVM. Thoughts ?
Thanks.
