I tried to apply this commit to 3.2.34 (and 3.2.32) but it failed to 
apply. Looking at the git log between 3.2.34 and 3.3 I assumed it also 
needed commit 5ef30ee53b187786e64bdc1f8109e39d17f2ce58.

I cherry picked commits 5ef30ee53b187786e64bdc1f8109e39d17f2ce58 and 
5195d8e217a78697152d64fc09a16e063a022465 and tried to compile the 
result, but it failed with the following error:

kernel/auditsc.c:2189: error: conflicting types for ‘__audit_mq_open’
include/linux/audit.h:477: note: previous declaration of 
‘__audit_mq_open’ was here
kernel/auditsc.c:2289: error: conflicting types for ‘__audit_ipc_set_perm’
include/linux/audit.h:471: note: previous declaration of 
‘__audit_ipc_set_perm’ was here

Any idea on how to determine which intermediate patches are also needed? 
Or should I just try to modify commit 
5195d8e217a78697152d64fc09a16e063a022465 to make it apply?

Regards,

Rik
