Machine: amd64
>Description:

assym.h doesn't depend on the header files it's derived from. This
results in out of date info and crashes in locore if core data
structures are changed.

Might be specific to amd64 but I assume most of the logic involved is
MI.

I doubt this has been true forever so it was probably caused by some
of the recent config and kernel build rototilling.

>How-To-Repeat:

valkyrie% touch ../../../../sys/proc.h 
valkyrie% make assym.h
`assym.h' is up to date.
valkyrie%
