212aa33226 kernel: enable memory compaction
Compaction is the only memory management component to form high order (larger
physically contiguous) memory blocks reliably. The page allocator relies on
compaction heavily and the lack of the feature can lead to unexpected OOM
killer invocations for high order memory requests. You shouldn't disable this
option unless there really is a strong reason for it.

77e3e706ce kernel: add missing ARM64_SSBD symbol
In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for
ARM64. Add this symbol to all ARM64 targets using kernel 4.14.

This mitigates CVE-2018-3639 on ARM64.

67a3cdcbb0 kernel: enable THIN_ARCHIVES by default
THIN_ARCHIVES option is enabled by default in the kernel configuration
and no one target config disables it. So enable it by default and remove
this symbol from target specific configs to keep them light.

bdc2b58c4b kernel: enable FUTEX_PI by default
New FUTEX_PI configuration symbol enabled if FUTEX and RT_MUTEX symbols
are enabled. Both of these symbols are enabled by default in the
generic config, so enable FUTEX_PI by default too to keep platform
specific configs minimal.
