Absolutely and agreed, will fix this ASAP!

wait.h generates too large functions anyway, so uninlining parts of it will be an 
improvement anyway.

I did a fair amount of allyes/allno/allmod plus randconfig testing on x86, and 
caught and fixed a number of cases, so that angle should be covered to a fair 
degree.

On non-x86 I did allyes/allno/allmod testing as well, but not randconfig testing - 
plus some of the architectures have a large amount of defconfigs which I couldn't 
all test through.

So I'd expect build breakages to be concentrated into newly upstreamed code (such 
as this one) - which risk I tried to reduce by re-testing them on the almost-last 
day of the merge window.

Thanks,

	Ingo
