    sys/ia64/ia64        exception.s genassym.c locore.s machdep.c 
                         support.s swtch.s trap.c vm_machdep.c

  Log:
  * Fix exception handling so that it actually works. We can now handle
    exceptions from both kernel and user mode.
  * Fix context switching so that we can switch back to a proc which we
    switched away from (we were saving the state in the wrong place).
  * Implement lazy switching of the high-fp state. This needs to be looked
    at again for SMP to cope with the case of a process migrating from one
    processor to another while it has the high-fp state.
  * Make setregs() work properly. I still think this should be called
    cpu_exec() or something.
  * Various other minor fixes.
  
  With this lot, we can execve() /sbin/init and we get all the way up to its
  first syscall. At that point, we stop because syscall handling is not done
  yet.
