requires the command line option -mavx2. Since GCC also supports that,
remove the pragma lines and add the -mavx2 option when building the

the correct value into functions which use an ARMMMUIdx.
o Fixed comments in helper.c which referred to non-existent instructions.
Testing:
o Booted Linux 5.11 - verified the previous assert failure in qemu is
resolved.
o Ran checkpatch.pl.
