Kernel 4.12 reads MSR 0x140, MSR_XEON_PHI_MISC_FEATURE_ENABLES_REGISTER and it causes CPU hang if CPU is in VMM mode. Solution: Set MsrBitmap to 1 and set the corresponding bits in mGuestContextCommon.MsrBitmap. Make VMM service the MSR read/write requests only if the MSR handler is defined in MsrHandler.c. Testing: Verified pass with Minnowboard max.
