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.

Florian Fainelli 0cf7c54023 armvirt: Resync kernel configuration
The 4.14 kernel configuration defaulted to a v4/v5 multiplatform while
4.9 was using a v6/v7 default configuration. Resync 4.14 against 4.9 so
they are nearly identical.

Jo-Philipp Wich 57157618d4 armvirt: re-enable VFP support
Enable CONFIG_VFP again which was disabled during the 4.9 -> 4.14 bump.

Boot tested both 32 and 64 bit subtargets using initramfs images with the
qemu-system-arm and qemu-system-aarch64 emulators.

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.

Stijn Tintel 1e91855af2 armvirt: rename config-default to config-4.9
The kernel configs for all targets should have the version in the
filename, for clearness and consistency across all targets.
It is also expected by the update_kernel.sh script.

Yousong Zhou 6138d84243 armvirt: 64: enable usb support
It was originally only enabled for the "32" subtarget along with the
"usb" feature which is now also shared by the "64" target

This should fix the phase1 build of armvirt/64

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")
