-// ARMv7 and newer support native unaligned accesses, but only of 16-bit

-// do an unaligned read and rotate the words around a bit, or do the reads very
-// slowly (trip through kernel mode). There's no simple #define that says just
-// “ARMv7 or higher”, so we have to filter away all ARMv5 and ARMv6
-// sub-architectures. Newer gcc (>= 4.6) set an __ARM_FEATURE_ALIGNED #define,
-// so in time, maybe we can move on to that.

-// This is a mess, but there's not much we can do about it.
