What are the implications of this? I think we should either go __asm__
__volatile__ or asm volatile for the sake of looking at the code without
eye cancer, but not mix it.

We're absolutely gcc specific, so discussing about asm not being
reserved sounds a bit vain. Also, is __asm__ reserved? Reserved by whom?
I know more compilers that know about asm than __asm__ if we're really
trying to become non-GNU-centric.

What's the goal of your patch?
