x86: TSX Async Abort protections not restored after S3 This issue relates
to the TSX Async Abort speculative security vulnerability. Please see
https://xenbits.xen.org/xsa/advisory-305.html for details. Mitigating TAA
by disabling TSX (the default and preferred option) requires selecting a
non-default setting in MSR_TSX_CTRL. This setting isn’t restored after S3
suspend.
