Userland starts to fail for simple tasks like 'ls -la'. The test was
done with 64bit SMP on a board which needs the m3 workaround. The
current CVS version works.

I guess the failure is caused by some missing bits for the m3
workaround which only show up for the optimized handlers in 64bit mode.

I have tested my patch on a SGI O2 R5000 in the meanwhile, also with
good results.
