From: Manfred Spraul <manfred@colorfullife.com>
Attached is a patch that replaces the #ifndef CONFIG_SYSV syscall stubs
with cond_syscall stubs. I did the diff against 2.6.2, but it applies to
2.6.3 and 2.6.3-mm1 as well.
The patch could be called "-1/5" of the series that adds posix message
queues - without it, hch won't stop objecting to the message queue patches
;-)
