There are quite a lot of different things going on here, all of which are
interleaved in this patch. Could you split them out into smaller simpler changes?

The bits I count are:
* Pulling 32bit specific eabi and fallback macro out into compiler.h,
* Adding support for __vdso_clock_getres,
* Flipping tk_is_cntvct's logic to become use_syscall,
* Variable renames to align 32/64 bit,

...are those 'coarse' versions of the timer calls being added, or just moved around?


Thanks,

James
