DC CVAP and DC CVADP instructions can be executed in EL0 on Linux,
either directly when SCTLR_EL1.UCI == 1 or emulated by the kernel (see
user_cache_maint_handler() in arch/arm64/kernel/traps.c).
This patch enables execution of the two instructions in user mode
emulation.

Yes, exactly. Since we pass -Werror, ifdef'ing out the if statement
wouldn't even compile.
