   An update that solves one vulnerability and has 8 fixes is
   now available.

Description:


   The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive
   various security and bugfixes.

   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).
