kernel: Update to 4.14.14/4.9.77/4.4.112

The 4.4.14 has a number of important fixes/additions:
- New support for retpolines (enabled but requires newer gcc
  to take advantage of). This provides mitigation for Spectre
  style attacks.
- Various KPTI fixes including fixes for EFI booting
- More eBPF fixes around out-of-bounds and overflow of
  maps. These were used for variant 1 of CVE-2017-5753.
- Several KVM related to CVE-2017-5753, CVE-2017-5715,
  CVE-2017-17741.
- New sysfs interface listing vulnerabilities:
  /sys/devices/system/cpu/vulnerabilities

The 4.9.77 kernel also has seems to have most/all of the above
back-ported.

See https://lwn.net/SubscriberLink/744287/1fc3c18173f732e7/
for more details on the Spectre mitigation.
