We need to move it out of __init so we don't have section mismatch problems.

I'd rather keep KVM bits out of uasm.h.  A select EXPORT_UASM in Kconfig
would have been cleaner - but read below.

A __uasminit tag is a bit unobvious because set_except_vector is not part of
uasm.  I could understand __cpuinit - but of course that doesn't sort your
problem.  Maybe we should just drop the __init tag alltogether?  Or if we
really want set_except_vector to become part of the uasm subsystem, then
probably it's declaration should move from setup.h to uasm.h.
