When calculating the minimum ird in c4iw_accept_cr(), we need to always
have a value of at least 1 if the RTR message is a 0B read.  The code

The INIT_UDATA() macro requires a pointer or unsigned long argument for

Pick up the late fixes from the 4.3 cycle so we have them in our
next branch.

ib_send_cm_sidr_rep could sometimes erase the node from the sidr
(depending on errors in the process). Since ib_send_cm_sidr_rep is
called both from cm_sidr_req_handler and cm_destroy_id, cm_id_priv
could be either erased from the rb_tree twice or not erased at all.
Fixing that by making sure it's erased only once before freeing
cm_id_priv.

When discussing the patches to demux ids in rdma_cm instead of ib_cm, it
was decided that it is best to use the P_Key value in the packet headers.
However, the mlx5 and ipath drivers are currently unable to send correct
P_Key values in GMP headers. They always send using a single P_Key that is
set during the GSI QP initialization.

Change the rdma_cm code to look at the P_Key value that is part of the
packet payload as a workaround. Once the drivers are fixed this patch can
be reverted.
