MFC r198212,198378,198427,198428,198723,198724,198725,198731:
	SMP support for PowerPC G5 systems.

r198724:
	Fix a race in casuword() exposed by csup. casuword() non-atomically
read the current value of its argument before atomically replacing it,
which could occasionally return the wrong value on an SMP system. This
resulted in user mutex operations hanging when using threaded applications.

r198723,198725,198731:
	Loop on blocked threads when using ULE scheduler, removing an
XXX MP comment.

r198427:
	Add some more paranoia to setting HID registers, and update the AIM
clock routines to work better with SMP.

r198378:
	Add SMP support on U3-based G5 systems. While here, correct the
64-bit tlbie function to set the CPU to 64-bit mode correctly.

r198212:
	Don't assume that physical addresses are identity mapped. This
allows the second processor on G5 systems to start.
