kernel you are restricted to AArch64 user-mode binaries. This will be addressed
in a later patch.

arm: Add support for ARMv8 (AArch64 & AArch32)
Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64
kernel you are restricted to AArch64 user-mode binaries. This will be addressed
in a later patch.
Note: Virtualization is only supported in AArch32 mode. This will also be fixed
in a later patch.
