Broadwell and supports some additional features that are: MPX,
|
|
|
9ae3a8 |
XSAVEC, and XGETBV1.

Backport notes:
|
|
|
9ae3a8 |
* ARAT feature not included, as it is not available in the
|
|
|
9ae3a8 |
qemu-kvm-1.5.3 tree (and disabled by compat code in
|
|
|
9ae3a8 |
pc-i440fx-rhel7.2.0 and older on qemu-kvm-rhev)
