Hi Jan,

This issue was fixed in a generic way in the patch set that is in the
-mm tree. Had you tried your test case in the current -mm tree?

The problem you mentioned was fixed by saving and restoring the preempt
count as a part of the fault handling from the kgdb core and not in the
arch specific portion.
