Removing open-coded MAC formats shrinks the source and the generated
code too, eg on x86-64:
add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-103 (-103)
function old new delta
make_cm_node 932 912 -20
nes_netdev_set_mac_address 427 406 -21
nes_netdev_set_multicast_list 1148 1124 -24
nes_probe 2349 2311 -38

This converts the main ib_device to use struct device instead of struct
class_device as class_device is going away.

None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

Move the free_irq() call in nes_remove() to before the tasklet_kill();
otherwise there is a window after tasklet_kill() where a new interrupt
can be handled and reschedule the tasklet, leading to a use-after-free

Add a new IB_WR_SEND_WITH_INV send opcode that can be used to mark a
"send with invalidate" work request as defined in the iWARP verbs and
the InfiniBand base memory management extensions. Also put "imm_data"
and a new "invalidate_rkey" member in a new "ex" union in struct
ib_send_wr. The invalidate_rkey member can be used to pass in an
R_Key/STag to be invalidated. Add this new union to struct
ib_uverbs_send_wr. Add code to copy the invalidate_rkey field in
ib_uverbs_post_send().
Fix up low-level drivers to deal with the change to struct ib_send_wr,
and just remove the imm_data initialization from net/sunrpc/xprtrdma/,
since that code never does any send with immediate operations.
Also, move the existing IB_DEVICE_SEND_W_INV flag to a new bit, since
the iWARP drivers currently in the tree set the bit. The amso1100
driver at least will silently fail to honor the IB_SEND_INVALIDATE bit
if passed in as part of userspace send requests (since it does not
implement kernel bypass work request queueing). Remove the flag from
all existing drivers that set it until we know which ones are OK.
The values chosen for the new flag is not consecutive to avoid clashing
with flags defined in the XRC patches, which are not merged yet but
which are already in use and are likely to be merged soon.
This resurrects a patch sent long ago by Mikkel Hagen <mhagen@iol.unh.edu>.

Add a create_flags member to struct ib_qp_init_attr that will allow a
kernel verbs consumer to create a pass special flags when creating a QP.
Add a flag value for telling low-level drivers that a QP will be used
for IPoIB UD LSO. The create_flags member will also be useful for XRC
and ehca low-latency QP support.
Since no create_flags handling is implemented yet, add code to all
low-level drivers to return -EINVAL if create_flags is non-zero.

In list iteration code, you normally wouldn't be calling
"container_of()" directly anyway, you'd be invoking "list_entry()".
But you don't even need that here, "list_for_each_entry()" is fine.

The session_id members of struct nes_cm_listener and struct
nes_cm_node are write-only, so remove them. This allows the
session_id member of struct nes_cm_core to be removed as well, since
it is only used to write those other session_id values.
This removes the use of current->tgid (which will be deprecated)
pointed out by Pavel Emelyanov <xemul@openvz.org>.

On some platforms, eg sparc64, dma_addr_t is not the same size as a
pointer, so printing dma_addr_t values by casting to void * and using
a %p format generates warnings. Fix this by casting to unsigned long
and using %lx instead. This fixes the warnings:
drivers/infiniband/hw/nes/nes_verbs.c: In function 'nes_setup_virt_qp':
drivers/infiniband/hw/nes/nes_verbs.c:1047: warning: cast to pointer from integer of different size

nes_unregister_ofa_device() dereferences the nesibdev pointer before
testing if it's NULL. Also, the test is doubly redundant because the
only caller of nes_unregister_ofa_device() is nes_destroy_ofa_device(),
which already tests if nesibdev is NULL. Remove the unnecessary test.
This was spotted by the Coverity checker (CID 2190).

With commit ef19454b ("[LIB] crc32c: Keep intermediate crc state in
cpu order"), the behavior of crc32c changes on big-endian platforms.
Our algorithm expects the previous behavior; otherwise we have RDMA
connection establishment failure on big-endian platforms like powerpc.
Apply cpu_to_le32() to value returned by crc32c() to get the previous
behavior.

Adrian Bunk pointed out that a Coverity scan found some apparently
dead code in nes_verbs.c that really shouldn't have been dead.
The function nes_create_cq() was missing the assignment
err = 1;
just prior to an iteration that conditionally set err = 0 if a PBL was
found for a given virtual CQ. I also noticed we should have been
returning -EFAULT on a couple related error paths.

In nes_create_qp(), the test
if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) {
is used to error out if the db_index is too large; however, if the
test doesn't trigger, then the index is used as
nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp;
and mmap_nesqp is declared as
struct nes_qp *mmap_nesqp[NES_MAX_USER_WQ_REGIONS];
which leads to an array overrun if the index is exactly equal to
NES_MAX_USER_WQ_REGIONS. Fix this by bailing out if the index is
greater than or equal to NES_MAX_USER_WQ_REGIONS.
This was spotted by the Coverity checker (CID 2162).
