Wanpeng Li ae95f566b3 KVM: X86: TSCDEADLINE MSR emulation fastpath 
This patch implements a fast path for emulation of writes to the TSCDEADLINE
MSR.  Besides shortcutting various housekeeping tasks in the vCPU loop,
the fast path can also deliver the timer interrupt directly without going
through KVM_REQ_PENDING_TIMER because it runs in vCPU context.
