I really dislike the first patch... Preferably I'd simply fully revert
all the jump-label stuff and try again next round with a saner
interface.

There's a really good simple fix for this, simply disable the gcc
trickery for .37 and use the fallback.

Then for .38, mandate the key type to be atomic_t * and switch to the
SWITCH_POINT() interface from hpa.
