Hi,

quoted

ipc/syscall.c:17: error: conflicting types for ‘sys_ipc’
include/linux/syscalls.h:691: note: previous declaration of ‘sys_ipc’ was here

Hmm. Right you are. Why don't I see this? (I already applied the patch)

Ahh. Because this only triggers with __ARCH_WANT_SYS_IPC. But why didn't 
Anton see it then? 

Anyway, I assume the following fixes it. Can you verify?

Sorry, I forgot to quilt add. Stupid screw up, thanks Andreas for catching
it so quickly.

Anton
