Seperate members of "struct pcb" that are accessed using physical addresses from thos that are exclusively accessed using virtual addresses and add padding between them to make sure they don't share a cache line.  Fixes random crashes on at least PA-8700 and PA-7200 based machines.  Without this, the PA-7200 based C110 wouldn't stay up long enough to do an install.
