Update of /cvsroot/linux-vax/kernel/Documentation/vax
In directory slayer.i.sourceforge.net:/tmp/cvs-serv31374/Documentation/vax

Modified Files:
	memory.txt 
Log Message:
Added note on memory layout.  Add some spare entries onto the end
of the system page table for mapping I/O pages and for use by
vmalloc().  Replace GET_SPTE macro with GET_SPTE_PHYS and GET_SPTE_VIRT.
Flush translation buffers where necessary (before turning on VM and
after modifying SPTEs).  Clear and enable level 2 cache on KA650
CPUs (makes mem_init() approx 15% faster).
