[PATCH] Make RCU API inaccessible to non-GPL Linux kernel modules
Remove synchronize_kernel() (deprecated 2-APR-2005 in http://lkml.org/lkml/2005/4/3/11) and makes the RCU API inaccessible to non-GPL Linux kernel modules (as was announced more than one year ago in http://lkml.org/lkml/2005/4/3/8). Tested on x86 and ppc64. Signed-off-by: "Paul E. McKenney" <paulmck@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

-What: RCU API moves to EXPORT_SYMBOL_GPL
-When: April 2006
-Files: include/linux/rcupdate.h, kernel/rcupdate.c
-Why: Outside of Linux, the only implementations of anything even
- vaguely resembling RCU that I am aware of are in DYNIX/ptx,
- VM/XA, Tornado, and K42. I do not expect anyone to port binary
- drivers or kernel modules from any of these, since the first two
- are owned by IBM and the last two are open-source research OSes.
- So these will move to GPL after a grace period to allow
- people, who might be using implementations that I am not aware
- of, to adjust to this upcoming change.

What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
When: November 2006
Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
