The way I've organized my patch series is with the arch support split up

This patch backports from 2.6.19 a fix to a 2.6.18 regression.
Like for PTRACE_OLDSETOPTIONS, we should fix PTRACE_[GS]ET_THREAD_AREA. This had
been done already for 2.6.19, so this is for 2.6.18-stable only.
This was tested with UML/32bit as API consumer, both before and after this
patch.

Move the host_info string from util.c to um_arch.c, where it is
actually initialized and used. Also document its lack of locking.

Add some locking to host_ldt_entries to prevent racing when reading
LDT information from the host.
Also fixed some style violations.

Please remove GFP_KERNEL allocation under spin_lock - simplest way is using a
mutex unless this can be important for performance.

I started uml_daemon as root by mistake, so /tmp/uml.ctl even if /dev/net/tun
was world-readable. Ok, I did it. This is the result (after trying many times
to do 'ifconfig eth0 up' inside UML):
