A reorganisation of the PD allocation and deallocation in commit
9ba1377daa ("RDMA/ocrdma: Move PD resource management to driver.")
introduced a double free on pd, as detected by static analysis by
smatch:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:682 ocrdma_alloc_pd()
error: double free of 'pd'^
The original call to ocrdma_mbx_dealloc_pd() (which does not kfree
pd) was replaced with a call to _ocrdma_dealloc_pd() (which does
kfree pd). The kfree following this call causes the double free,
so just remove it to fix the problem.

This driver already makes use of ioremap_wc() on PIO buffers,
so convert it to use arch_phys_wc_add().
The qib driver uses a mmap() special case for when PAT is
not used, this behaviour used to be determined with a
module parameter but since we have been asked to just
remove that module parameter this checks for the WC cookie,
if not set we can assume PAT was used. If its set we do
what we used to do for the mmap for when MTRR was enabled.
The removal of the module parameter is OK given that Andy
notes that even if users of module parameter are still around
it will not prevent loading of the module on recent kernels.

Currently the iw_cxgb4 implementation requires the qp and cq qid densities
to match as well as the qp and cq id ranges. So fail a device open if
the device configuration doesn't meet the requirements.
The reason for these restictions has to do with the fact that IQ qid X
has a UGTS register in the same bar2 page as EQ qid X. Thus both qids
need to be allocated to the same user process for security reasons.
The logic that does this (the qpid allocator in iw_cxgb4/resource.c)
handles this but requires the above restrictions.

set_filter_wr is requesting __GFP_NOFAIL allocation although it can return
ENOMEM without any problems obviously (t4_l2t_set_switching does that
already). So the non-failing requirement is too strong without any
obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the
failure paths easier.
The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL
and then checks the return value and returns -ENOMEM on failure. This
doesn't make any sense what so ever. Either the allocation cannot fail or
it can.
del_filter_wr seems to be safe as well because the filter entry is not
marked as pending and the return value is propagated up the stack up to
c4iw_destroy_listen.

The current code decreases from the mss size (which is the gso_size
from the kernel skb) the size of the packet headers.
It shouldn't do that because the mss that comes from the stack
(e.g IPoIB) includes only the tcp payload without the headers.
The result is indication to the HW that each packet that the HW sends
is smaller than what it could be, and too many packets will be sent
for big messages.
An easy way to demonstrate one more aspect of the problem is by
configuring the ipoib mtu to be less than 2*hlen (2*56) and then
run app sending big TCP messages. This will tell the HW to send packets
with giant (negative value which under unsigned arithmetics becomes
a huge positive one) length and the QP moves to SQE state.

If the SM rejects an alias GUID request the PF driver keeps trying to acquire
the specified GUID indefinitely, utilizing an exponential backoff scheme.
Retrying is managed per GUID entry. Each entry that wasn't applied holds its
next retry information. Retry requests to the SM consist of records of 8
consecutive GUIDS. Each record that contains GUIDs requiring retries holds its
next time-to-run based on the retry information of all its GUID entries. The
record having the lowest retry time will run first when that retry time
arrives.
Since the method (SET or DELETE) as sent to the SM applies to all the GUIDs in
the record, we must handle SET requests and DELETE requests in separate SM
messages (one for SETs and the other for DELETEs).
To avoid race conditions where a GUID entry request (set or delete) was
modified after the SM request was sent, we save the method and the requested
indices as part of the callback's context -- thus, only the requested indexes
are evaluated when the response is received.
When an GUID entry is approved we turn off its retry-required bit, this
prevents redundant SM retries from occurring on that record.
The port down event should be sent only when previously it was up. Likewise,
the port up event should be sent only if previously the port was down.
Synchronization was added around the flows that change entries and record state
to prevent race conditions.
