The following security bug was fixed:
- CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and
 AVX registers) between processes. These registers might contain
 encryption keys when doing SSE accelerated AES enc/decryption
 (bsc#1087086)
The following non-security bugs were fixed:
- KVM: x86: Sync back MSR_IA32_SPEC_CTRL to VCPU data structure
 (bsc#1096242, bsc#1096281).
- Xen counterparts of eager FPU implementation.
- x86/boot: Fix early command-line parsing when partial word matches
 (bsc#1096140).
- x86/bugs: spec_ctrl must be cleared from cpu_caps_set when being
 disabled (bsc#1096140).
- xen/x86/CPU: Check speculation control CPUID bit (bsc#1068032).
- xen/x86/CPU: Sync CPU feature flags late (bsc#1075994 bsc#1075091).
- xen/x86/cpu: Factor out application of forced CPU caps (bsc#1075994
 bsc#1075091).
- xen/x86/cpu: Fix bootup crashes by sanitizing the argument of the
 'clearcpuid=' command-line option (bsc#1065600).
- xen/x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
- xen/x86/entry: Use IBRS on entry to kernel space (bsc#1068032).
- xen/x86/idle: Toggle IBRS when going idle (bsc#1068032).
- xen/x86/kaiser: Move feature detection up (bsc#1068032).");
