Ah - how legacy.Yeah, but since my distro of choice is 32bit only and I don't much
feel like porting it myself or using an unofficial port (slamd64) I'm
sticking with a 32bit userspace. And as long as userspace is pure
32bit there doesn't seem to be much point in building a 64bit kernel.
And I only have 2GB of RAM, so I don't have a use for the larger 64bit
address space.
I also don't run any apps that do a lot of math on >32bit numbers, so
there's not much gain there either.
I guess I would bennefit from the extra GPR's, but then I would at the
same time loose a bit by all pointers being 64bit - both lose some
disk space due to larger binaries and I'd have increased memory use
and less efficient L1/L2 cache use.
I don't think there would actually be much gain for me in switching to
a 64bit kernel with a 64bit userspace atm.
But if I'm wrong I'd of course love to hear about it :)
