In any case, fixing it is a snap.  Grep for the missing symbols in the
   /sys/arch/sparc/sparc/ directory, and you'll find that there is
   assembly code labeled "_ENTRY(fdchwintr)" and "_ENTRY(amd7930_trap)"
   in there.  Adding the forgotten underscores at the start of these
   names solves the problem.


hm.

looking at the sparc <machine/asm.h> i think you should change that
to ENTRY(xxx) and then it will use _C_LABEL() which will put the
underscore in, or not, as necessary.
