NetBSD/sys/compat/hpux/hpux_compat.c
thorpej d9bce7422e Move the obviously machine-dependent HP-UX compat code to hpux_machdep.{c,h}. 
A fair bit of this, the m68k core dump and exec goo, can probably be
made into a generic m68k hpux module, eventually.

More to be placed in hpux_machdep.c - keep your eyes peeled...
