Stijn Tintel 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.

Stijn Tintel 8b35da1552 kernel: move CONFIG_KASAN to generic config
While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN
symbol. Move it to generic config instead of defining it for all arm64
and x86/64 targets.

It was only added in 4.0, so not needed in config-3.18.

Yousong Zhou 88468f7e53 armvirt: merge arm64 as subtarget 64
Original armvirt target is now subtarget 32.  Other than that the built
result should remain the same as before

Besides old features already available with arm64, the new armvirt/64
subtarget will also have those features originally enabled for
armvirt/32 with commit 44ecfc2 ("armvirt: new target")
