[PATCH for-3.7 0/4] mlx4 SRIOV fixes, 64B CQE/EQE patches re-spin

Hi Roland, everyone

This series includes fixes for two bugs in the SRIOV code which were discovered in
production environment, lets get them upstream too...

Also, a respin of the 64B CQE/EQE patches (kernel and user-space), over the V1 posting
you were asking for max flexibility - e.g expose/force update of guests only if needed
and similarily for libmlx4, I think I have this now, would love feedback though.

I tested this with both modified/non-modified mlx4 guest drivers, and with
both modified/non-modified libmlx4. The only pain point I was hitting, 
if non modified libmlx4 on systems with CX3 and modified kernel, on
the V1 discussion Roland -- you made a comment we might need a module param 
here to provide admins a way to let systems with old libmlx4 to work
with fresh kernels?!

changes from previous versions to the kernel 64B CQE/EQE patch:

V0 pointer
	mlx4 http://marc.info/?l=linux-rdma&m=131805712306677&w=2
	libmlx4 http://marc.info/?l=linux-rdma&m=131805712306678&w=2

V1 pointer 
	mlx4 http://marc.info/?l=linux-rdma&m=133787002203027&w=2
	libmlx4 -- didn't have V1

V1 changes from V0:

 - unified the 64B CQE and EQE patches to one patch which takes an approach of 
   apply both or none, under the thinking that 99% FW will support both or none.
 - bump the ABI version towards user-space/libmlx4 only when needed and not always
 - added support for SRIOV, using the PF_CONTEXT_BEHAVIOUR_MASK mechanism

V2 changes:  
 - rebased to kernel 3.6+ (e.g pre 3.7-rc1) that includes the SRIOV/IB patches
 - revised/fixed the SRIOV flow 
 - revises/fixed the flow towards user-space
