From: Pawan Gupta <pawan.kumar.gu...@linux.intel.com>
TSX Async Abort (TAA) is a side channel attack on internal buffers in
some Intel processors similar to Microachitectural Data Sampling (MDS).
Some future Intel processors will use the ARCH_CAP_TAA_NO bit in the
IA32_ARCH_CAPABILITIES MSR to report that they are not vulnerable to
TAA. Make this bit available to guests.
