Anyway, could you take a look at the git tree at
git://git.kernel.org/pub/scm/linux/kernel/git/viro/um-header.git/,
branch x86_merge and comment?  It doesn't include stuff from this
thread (yet); what it does is
       * further headers cleanups
       * sys-{i386,x86_64} merged; all[1] x86-specific code taken first
to arch/um/sys-x86 and then (by final commit) to arch/x86/um.  IMO that's
the right place for it - target-dependent code is better off not hidden
from maintainers of the target arch.  When we get other ports to working
shape, their target-specific parts ought to go into arch/<target>/um.
       * hopefully saner treatment of sigcontext; should make life easier
for other ports.

[1] theoretically - in reality we still have more than a few x86-isms in
"generic" um headers in arch/um/include/asm.

Ok, will look at it in the next few days.
"sys-{i386,x86_64} merged" sounds great!
