__GFP_WAIT was used to signal that the caller was in atomic context and
could not sleep. Now it is possible to distinguish between true atomic
context and callers that are not willing to sleep. The latter should
clear __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing
__GFP_WAIT behaves differently, there is a risk that people will clear the
wrong flags. This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly
indicate what it does -- setting it allows all reclaim activity, clearing
them prevents it.

Previously, vlan id and source MAC were used from QP attributes. Since
the net device is now stored in the GID attributes, they could be used
instead of getting this information from the QP attributes.
IB_QP_SMAC, IB_QP_ALT_SMAC, IB_QP_VID and IB_QP_ALT_VID were removed
because there is no known libibverbs that uses them.
This commit also modifies the vendors (mlx4, ocrdma) drivers in order

Current implementation for MLX4_IB_QP_BLOCK_MULTICAST_LOOPBACK is not
supported when link layer is Ethernet.
This patch will add counter based implementation for multicast loopback
prevention. HW can drop multicast loopback packets if sender QP counter
index is equal to receiver QP counter index. If qp flag
MLX4_IB_QP_BLOCK_MULTICAST_LOOPBACK is set and link layer is Ethernet,
create a new counter and attach it to the QP so it will continue
receiving multicast loopback traffic but it's own.
The decision if to create a new counter is being made at the qp
modification to RTR after the QP's port is set. When QP is destroyed or
moved back to reset state, delete the counter.

Commit 96249d70dd70 ("IB/core: Guarantee that a local_dma_lkey
is available") allows ULPs that make use of the local dma key to keep
working as before by allocating a DMA MR with local permissions and
converted these consumers to use the MR associated with the PD
rather then device->local_dma_lkey.
ConnectIB has some known issues with memory registration
using the local_dma_lkey (SEND, RDMA, RECV seems to work ok).
Thus don't expose support for it (remove device->local_dma_lkey
setting), and take advantage of the above commit such that no regression
is introduced to working systems.
The local_dma_lkey support will be restored in CX4 depending on FW
capability query.

Pull rdma driver move from Doug Ledford:
"This is a move only, no functional changes.
I tried to get it in prior to the rc1 release, but we were waiting on
IBM to get back to us that they were OK with the deprecation and
eventual removal of this driver. That OK didn't materialize until
last week, so integration and testing time pushed us beyond the rc1
release.
Summary:
- Move ehca driver to staging/rdma and schedule for deletion"

|
|
The ehca driver is only supported on IBM machines with a custom EBus.
As they have opted to build their newer machines using more industry
standard technology and haven't really been pushing EBus capable
machines for a while, this driver can now safely be moved to the
staging area and scheduled for eventual removal. This plan was brought
to IBM's attention and received their sign-off.
