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.
