It is not safe. Although opinions vary. I wouldn't enable it on a
multi-user machine, but kernel-mm is not meant for such use.
I think, but it is really Juan/Nicolas who should do it, that the names and functions
of 2.6 kernels need a rethinking. Something along the lines
of:
kernel-desktop -> up, 4GB
-> smp/686, 4 GB
-> smp/athlon, 4 GB
I assume performance hit of 4 GB is not so bad.
I am also wondering how bad it would be to use an smp for up machines.
Anyone has benchmarks?
kernel-server -> up, 4 GB
-> smp/p3, 64 GB
-> smp/athlon, 64 GB
Perhaps more? Security can be in kernel-server via LIDS so i think
kernel-secure via grsec is obsolete (aside from that, many security minded people will
not use 2.6 for at least I year yet).
kernel-desktop can have all the preempt stuff and other things (setpcap?)
you do not want to have on your server.
