This patch renames DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH to avoid
confusion with the drivers default values (DEFAULT_MAX_RECV_DATA_SEGMENT_LENGTH
is the iscsi RFC specific default).

I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:
arch/alpha/kernel/err_common.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:

All RDMA drivers except ehca set class_dev->dev to their dma_device
value (ehca leaves this unset). dma_device is the only value that
makes any sense, so move this assignment to core/sysfs.c. This reduce
the duplicated code in the rest of the drivers and gives ehca a nice
/sys/class/infiniband/ehcaX/device symlink.

There are quite a few places in ipoib_cm.c where we know IRQs are
enabled because we do something that sleeps in the same function, so
we can convert several occurrences of spin_lock_irqsave() to a plain
spin_lock_irq(). This cleans up the source a little and makes the
code smaller too:

mthca_free_qp() already has local variables to hold the QP's send_cq
and recv_cq, so we can slightly clean up the calls to mthca_cq_clean()
by using those local variables instead of expressions like
to_mcq(qp->ibqp.send_cq).
Also, by cleaning the recv_cq first, we can avoid worrying about
whether the QP is attached to an SRQ for the second call, because we
would only clean send_cq if send_cq is not equal to recv_cq, and that
means send_cq cannot have any receive completions from the QP being
destroyed.
All this work even improves the generated code a bit:
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-5 (-5)
function old new delta
mthca_free_qp 510 505 -5

Commit b2875d4c ("IB/mthca: Always fill MTTs from CPU") causes a crash
in mthca_write_mtt() with non-memfree HCAs that have their memory
hidden (that is, have only two PCI BARs instead of having a third BAR
that allows access to the RAM attached to the HCA) on 64-bit
architectures. This is because the commit just before, c20e20ab
("IB/mthca: Merge MR and FMR space on 64-bit systems") makes
dev->mr_table.fmr_mtt_buddy equal to &dev->mr_table.mtt_buddy and
hence mthca_write_mtt() tries to write directly into the HCA's MTT
table. However, since that table is in the HCA's memory, this is
impossible without the PCI BAR that gives access to that memory.
This causes a crash because mthca_tavor_write_mtt_seg() basically
tries to dereference some offset of a NULL pointer. Fix this by
adding a test of MTHCA_FLAG_FMR in mthca_write_mtt() so that we always
use the WRITE_MTT firmware command rather than writing directly if
FMRs are not enabled.

Re-init of the kernel structures after a chip reset was leaving the
portdata structure for port zero in an inconsistent state, and a
pointer to it either stale (in re-init code) or NULL (in devdata)

interrupt access, prevents the crashes.

Improve port-sharing performance by allowing any process to receive
packets from the shared hardware port under a spin lock for mutual
exclusion. Previously, one process was nominated as the master and
that process was responsible for receiving all packets from the shared
hardware port and either consuming them or forwarding them to their
destination. This led to starvation problems for other processes when
the master process was busy in computation phases.

The port sharing feature mixed kernel virtual addresses as well as
physical addresses for the offset used to describe the mmap address to
map the InfiniPath hardware into user space. This had a conflict on
powerpc. The new scheme converts it to a physical address so it
doesn't conflict with chip addresses and yet still fits in 40/44 bits
so it isn't truncated by 32-bit applications calling mmap64().

Some types of packet errors are moderately common with longer IB
cables and large clusters, and are not reported with prints by other
IB HCA drivers. This suppresses those messages unless the new
__IPATH_ERRPKTDBG bit is set in ipath_debug. Reporting of temporarily
disabled frequent error interrupts was also made clearer
We also distinguish between chip errors, and bad packets sent or
received in the wording of the messages.

If a post send is done in loopback and there is no receive queue
entry, the sending QP is put on a timeout list for a while so the
receiver has a chance to post a receive buffer. If the another post
send is done, the code incorrectly tried to put the QP on the timeout
list again an corrupted the timeout list. This eventually leads to a
spin lock deadlock NMI due to the timer function looping forever with
the lock held.

A recent change was made to allocate memory for a port after CPU
affinity is set. That change didn't account for subports and was
trying to allocate memory for the port twice.

The chip documentation on the expected TID vs eager TID parity error
bits was reversed from what was implemented in the RTL, for both
chips. This corrects the definitions.

The loop which initializes the user memory region from an array of
pages was using the wrong limit for the array. This worked OK when
dma_map_sg() returned the same number as the number of pages. This
patch fixes the problem.
