5c67e5fad9 New device attachment scheme: 
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

ba893940d3 savectx() now justs syncs the pcb, it no longer needs to copy the stack.

on entry and exit. Added extra comments to indicate the states of
various registers throughout cpuswitch().
Added proc_trampoline function.

d253d345a2 Since kernel stack double mapping no longer exists there is no

d389b21913 Added boot time override for the memory test during probing. This 
memory test apparently causes hangups on some etherH interfaces.
Until this can be debugged with an offending interface the memory
test can be bypassed.
