Backmerge fixes since it's getting out of hand again with the massive
split due to atomic between -next and 4.2-rc. All the bugfixes in
4.2-rc are addressed already (by converting more towards atomic
instead of minimal duct-tape) so just always pick the version in next
for the conflicts in modeset code.

All the other conflicts are just adjacent lines changed.

IB/mad: Add final OPA MAD processing

For devices which support OPA MADs

1) Use previously defined SMP support functions.

2) Pass correct base version to ib_create_send_mad when processing OPA MADs.

3) Process out_mad_key_index returned by agents for a response. This is
necessary because OPA SMP packets must carry a valid pkey.

4) Carry the correct segment size (OPA vs IBTA) of RMPP messages within
ib_mad_recv_wc.

5) Handle variable length OPA MADs by:

* Adjusting the 'fake' WC for locally routed SMP's to represent the
proper incoming byte_len
* out_mad_size is used from the local HCA agents
1) when sending agent responses on the wire
2) when passing responses through the local_completions
function

NOTE: wc.byte_len includes the GRH length and therefore is different
from the in_mad_size specified to the local HCA agents.
out_mad_size should _not_ include the GRH length as it is added

IB/mad: Convert allocations from kmem_cache to kzalloc

This patch implements allocating alternate receive MAD buffers within the MAD
stack. Support for OPA to send/recv variable sized MADs is implemented later.

1) Convert MAD allocations from kmem_cache to kzalloc

kzalloc is more flexible to support devices with different sized MADs
and research and testing showed that the current use of kmem_cache does
not provide performance benefits over kzalloc.

2) Change struct ib_mad_private to use a flex array for the mad data
3) Allocate ib_mad_private based on the size specified by devices in
rdma_max_mad_size.
4) Carry the allocated size in ib_mad_private to be used when processing
ib_mad_private objects.
5) Alter DMA mappings based on the mad_size of ib_mad_private.
6) Replace the use of sizeof and static defines as appropriate
7) Add appropriate casts for the MAD data when calling processing
functions.
