[GIT PULL] OpenRISC bug fixes for 3.9

[GIT PULL] OpenRISC bug fixes for 3.9

[Jonas Bonn]

Hi Linus,

Here are 3 patches to fix OpenRISC build issues for 3.9.  2 of them are 
essential as the build is broken without them; the third patch, removing 
VIRT_TO_BUS, isn't strictly essential, but is harmless enough and 
removes an invalid config setting introduced during this cycle.

Thanks,
Jonas

   openrisc: remove HAVE_VIRT_TO_BUS (2013-03-13 06:12:39 +0100)

----------------------------------------------------------------
OpenRISC bug fixes for 3.9

* The GPIO descriptor work has exposed how broken the non-GPIOLIB
   bits for OpenRISC were.  We now require GPIOLIB as this is the
   preferred way forward.

* The system.h split introduced a bug in llist.h for arches using
   asm-generic/cmpxchg.h directly, which is currently only OpenRISC.
   The patch here moves two defines from asm-generic/atomic.h to
   asm-generic/cmpxchg.h to make things work as they should.

* The VIRT_TO_BUS selector was added for OpenRISC, but OpenRISC does
   not have the virt_to_bus methods, so there's a patch to remove it
   again.
