[Colin King]

From: Colin Ian King <colin.king at canonical.com>

https://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-2584.html

Note: backport removes changes to functions em_sgdt and fxrstor_fixup
as these don't exist in Trusty and were introduced in 2016 with commit
283c95d0e389 ("KVM: x86: emulate FXSAVE and FXRSTOR")
