Well, something has been *really* been messed up. If I understand things 
properly, you are able to compile fine a 2.6.5 UML, right?

The problem is that:
a) I think that file should include the "kernelspace" headers... however the 
kludges needed to do it are very fragile when Kbuild changes a bit (this 
problem has repeatedly showed up against Linux 2.6).

However, things should succeed anyway, BUT

b) your distro headers are messed up...; the first thing I see is that it uses 
the 2.6 headers. Now, the missing header should be located in 
/usr/include/asm/mach-default/. Probably it is there; however the kernel uses 
normally a -Iasm/mach-default, so that #include <mach_mpspec.h> works.
Since one cannot require user programs to add -I to compile, Debian should 
symlink everything from /usr/include/asm/mach-default/ into /usr/include; 
i.e.:
ln -s  /usr/include/asm/mach-default/* /usr/include.

Then retry the build, and also watch this thread:

"[uml-devel] patch for 2.6.6-rc1".

Bye and HTH!
