ee3b8c5b8b armvirt: Remove kernel 4.14 support
This target was switched to kernel 4.19 more than 6 months ago in commit
f342ffd300 ("treewide: kernel: bump some targets to 4.19") and now
with kernel 5.4 support being added it gets harder to support kernel
4.14 in addition to kernel 4.19 and 5.4.

46af22de16 kernel: Remove CONFIG_COMPAT
This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.

This reduces the attack surface on such systems and should also save
some memory.

32eb66881c kernel: Activate CONFIG_ARM64_SW_TTBR0_PAN
This activates "Emulate Privileged Access Never using TTBR0_EL1
switching" on ARM64.

This should prevent the kernel from reading code from user space in
kernel context.

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.

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.

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")
