[LCP]address space

[Angus Mackay]

the intel pentium pro and up (don't know if any AMD's) support 36 bit memory
addressing.

this allows machines with up to 64GB of ram, of course each process can only
have a 4GB address space but you can have lots of processes with 4GB of memory
allocated (actually I think it is still 2-3GB as the kernel is mapped in to the
upper part of the address space). I thought that newer kernels supported this
functionality (windows NT does) but I am not sure.

these machines are generally hyper expensive though and only really from Compaq
(they usually have 4 or 8 cpus too).

cheers, Angus.
