This series add checks to make sure that the AArch32 state is
supported before we process the 32bit ID registers. Also
checks the same for COMPAT binary execution.

This series applies on top of 4.5-rc1 + Early CPU feature verification [1] +
Handle sign bit for CPU Features [2], even though review
doesn't require going through [1] & [2].
