x86: missing NULL pointer check in VMFUNC emulation

ISSUE DESCRIPTION When support for the Intel VMX VMFUNC leaf 0 was added, a new optional function pointer hvmemulvmfunc was added to the hvmemulateops table. As is intended, that new function pointer is NULL on non-VMX hardware, including AMD SVM hardware. However at a call site, the necessary NU...

FreeBSD : xen-kernel -- x86 CMPXCHG8B emulation fails to ignore operand size override (80a897a2-c1a6-11e6-ae1b-002590263bf5)

The Xen Project reports : The x86 instruction CMPXCHG8B is supposed to ignore legacy operand size overrides; it only honors the REX.W override making it CMPXCHG16B. So, the operand size is always 8 or 16. When support for CMPXCHG16B emulation was added to the instruction emulator, this restrictio...
