Ok, I see. At least that version seems ok because the code is cpu
specific already.
The omap do_wfi macro is specifically meant to avoid the multi-cpu
case by using the hexadecimal notation, so it can still be used while
building a kernel for ARMv6 or lower. Dave's version seems to have
the opposite intention here (choosing one version per arch level),
so it wouldn't be a replacement.
