Subject: [PATCH 1/2] cpu_map: Add TAA_NO bit for IA32_ARCH_CAPABILITIES MSR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CVE-2019-11135
CPUs with TAA_NO bit of IA32_ARCH_CAPABILITIES MSR set to 1 are not
vulnerable to TSX Asynchronous Abort and passing this bit to a guest
may avoid unnecessary mitigations.

Subject: [PATCH] cpu_map: Add TSX_CTRL bit for IA32_ARCH_CAPABILITIES MSR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CVE-2019-11135
When TSX_CTRL bit of IA32_ARCH_CAPABILITIES MSR is set to 1, the CPU
supports IA32_TSX_CTRL MSR which can be used to disable and/or mask TSX.
