Yes.  And it should be a little bit manual too.  For example, using your
regex (thanks!) I see we have some powerpc code that's doing
asm("eieio") and that should be eieio() (which is in turn an asm
volatile ...), as well as some sync;isync or just sync/isync that should
be sync();isync(); or similar.  And people that know x86 might have some
useful comments there too.
