Log message:
Get rid of non-equivalent aliases of the pcb by moving the fpu state out
of the pcb and using the p_addr member of 'struct proc' to calculate the
address of the kernel stack when switching to virtual mode after taking a trap.
Remove the now unecessary cache flushes; they're actually harmful since they
create non-equivalent aliases. This seems to fix the memory corruption we
have been observing from time to time.
This diff does not rename fpu_curpcb, which is now somewhat incorrectly named.
I hope to change things back again as soon as we are able to map the pcb 1:1.
