[task #5782] Handling of large memory equipment by GNU Mach

[anonymous]

Follow-up Comment #1, task #5782 (project hurd):

Well, this doesn't really have to do with the patch. The patch just makes it
clear that with its current memory layout, GNU can't handle more than 1GB.

Using another memory layout _is_ possible: Linux people have done it with
their "HIGHMEM" option. But this is a horrible bug-prone mess which now
reveals to be useless since we will all have 64bits-capable systems sooner or
later, won't we? ;)

So I'd say "why bother?". If people want more than 1GB, they should just buy
64. At the time we are really able to fill 1GB with KDE/Gnome/OOo/whatever, I
guess we will all have 64.

Note: this is not exactly 1GB, yes. Again, we might do like Linux: shift the
1GB/3GB limit between kernel and user so that the kernel can really map 1GB
of memory.
