[PATCH 0/2] arm64: traps.c fix + cleanup

[Mark Rutland]

Vladimir pointed out that we have an issue with handling undefined
instruction when both PAN & UAO are in use, due to dump_instr always
using KERNEL_DS, regardles of the context of the undefined instruction.
Patch 1 addresses this.

While investigating, I noticed that our dump_mem usage looked a bit
suspicious. It turns out that we try to handle a case that doesn't
happen in practice, and do so inconsistently, but as the code is never
called this is not harmful in practice. Patch 2 removes the redundant
code.

Thanks,
Mark.
