Do not meddle in the internals of kernels, for they are subtle and quick to
panic.

Avi:
This patch is to avoid saving and restoring of msr_efer on
lightweight vmexit.
With this patch, the Kernel build get 10% increasement for
64bits on 64 bits,
and 5-8% increasement for 32bits on 64 bits.
Vmexit.flat can see ~1185 cycles save for 64 bits on 64 bi
