Pick up the waitqueue related renames - it didn't get much feedback,
so it appears to be uncontroversial. Famous last words? ;-)

So I've noticed a number of instances where it was not obvious from the
code whether ->task_list was for a wait-queue head or a wait-queue entry.
Furthermore, there's a number of wait-queue users where the lists are
not for 'tasks' but other entities (poll tables, etc.), in which case
the 'task_list' name is actively confusing.
To clear this all up, name the wait-queue head and entry list structure
fields unambiguously:
struct wait_queue_head::task_list => ::head
struct wait_queue_entry::task_list => ::entry
For example, this code:
rqw->wait.task_list.next != &wait->task_list
... is was pretty unclear (to me) what it's doing, while now it's written this way:
rqw->wait.head.next != &wait->entry
... which makes it pretty clear that we are iterating a list until we see the head.
Other examples are:
list_for_each_entry_safe(pos, next, &x->task_list, task_list) {
list_for_each_entry(wq, &fence->wait.task_list, task_list) {
... where it's unclear (to me) what we are iterating, and during review it's
hard to tell whether it's trying to walk a wait-queue entry (which would be
a bug), while now it's written as:
list_for_each_entry_safe(pos, next, &x->head, entry) {
list_for_each_entry(wq, &fence->wait.head, entry) {

Rename:
wait_queue_t => wait_queue_entry_t
'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.
Start sorting this out by renaming it to 'wait_queue_entry_t'.
This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',
which is the more canonical nomenclature for such data types.

A divide by zero error occurs if qp_count is less than mw_count because
num_qps_mw is calculated to be zero. The calculation appears to be
incorrect.
The requirement is for num_qps_mw to be set to qp_count / mw_count
with any remainder divided among the earlier mws.
For example, if mw_count is 5 and qp_count is 12 then mws 0 and 1
will have 3 qps per window and mws 2 through 4 will have 2 qps per window.
Thus, when mw_num < qp_count % mw_count, num_qps_mw is 1 higher
than when mw_num >= qp_count.

In cases where there are more mw's than spads/2-2, the mw count gets
reduced to match the limitation. ntb_transport also tries to ensure that
there are fewer qps than mws but uses the full mw count instead of
the reduced one. When this happens, the math in
'ntb_transport_setup_qp_mw' will get confused and result in a kernel
paging request bug.
This patch fixes the bug by reducing qp_count to the reduced mw count
instead of the full mw count.

Pull rdma fixes from Doug Ledford:
"I had thought at the time of the last pull request that there wouldn't
be much more to go, but several things just kept trickling in over the
last week.
Instead of just the six patches to bnxt_re that I had anticipated,
there are another five IPoIB patches, two qedr patches, and a few
other miscellaneous patches.
The bnxt_re patches are more lines of diff than I like to submit this
late in the game. That's mostly because of the first two patches in
the series of six. I almost dropped them just because of the lines of
churn, but on a close review, a lot of the churn came from removing
duplicated code sections and consolidating them into callable
routines. I felt like this made the number of lines of change more
acceptable, and they address problems, so I left them. The remainder
of the patches are all small, well contained, and well understood.
These have passed 0day testing, but have not been submitted to
linux-next (but a local merge test with your current master was
without any conflicts).
Summary:
- A fix for fix eea40b8f624 ("infiniband: call ipv6 route lookup via
the stub interface")
- Six patches against bnxt_re...the first two are considerably larger
than I would like, but as they address real issues I went ahead and
submitted them (it also helped that a good deal of the churn was
removing code repeated in multiple places and consolidating it to
one common function)
- Two fixes against qedr that just came in
- One fix against rxe that took a few revisions to get right plus
time to get the proper reviews
- Five late breaking IPoIB fixes
- One late cxgb4 fix"

What this means is that the gadgetfs_suspend() routine was trying to
access dev->lock after it had been deallocated. The root cause is a
race in the dummy_hcd driver; the dummy_udc_stop() routine can race
with the rest of the driver because it contains no locking. And even
when proper locking is added, it can still race with the
set_link_state() function because that function incorrectly drops the
private spinlock before invoking any gadget driver callbacks.
The result of this race, as seen above, is that set_link_state() can
invoke a callback in gadgetfs even after gadgetfs has been unbound
from dummy_hcd's UDC and its private data structures have been
deallocated.
include/linux/usb/gadget.h documents that the ->reset, ->disconnect,
->suspend, and ->resume callbacks may be invoked in interrupt context.
In general this is necessary, to prevent races with gadget driver
removal. This patch fixes dummy_hcd to retain the spinlock across
these calls, and it adds a spinlock acquisition to dummy_udc_stop() to
prevent the race.
The net2280 driver makes the same mistake of dropping the private
spinlock for its ->disconnect and ->reset callback invocations. The
patch fixes it too.
Lastly, since gadgetfs_suspend() may be invoked in interrupt context,
it cannot assume that interrupts are enabled when it runs. It must
use spin_lock_irqsave() instead of spin_lock_irq(). The patch fixes
that bug as well.

According to the eLCDIF initialization steps listed in the MX6SX
Reference Manual the eLCDIF block reset is mandatory.
Without performing the eLCDIF reset the display shows garbage content
when the kernel boots.
In earlier tests this issue has not been observed because the bootloader
was previously showing a splash screen and the bootloader display driver
does properly implement the eLCDIF reset.
Add the eLCDIF reset to the driver, so that it can operate correctly
independently of the bootloader.
Tested on a imx6sx-sdb board.

After finished I2C block read/write, when unmap the data buffer,
a wrong device address was pass to dma_unmap_single().
To fix this, give dma_unmap_single() the "dev" parameter, just like
what dma_map_single() does, then unmap can find the right devices.

Since version 3.0.0 of the SMBIOS specification, there can be
multiple entry points in memory, pointing to one or two DMI tables.
If both a 32-bit ("_SM_") entry point and a 64-bit ("_SM3_") entry
point are present, the specification requires that the latter points
to a table which is a super-set of the table pointed to by the
former. Therefore we should give preference to the 64-bit ("_SM3_")
entry point.
However, currently the code is picking the first valid entry point
it finds. Per specification, we should look for a 64-bit ("_SM3_")
entry point first, and if we can't find any, look for a 32-bit
("_SM_" or "_DMI_") entry point. Modify the code to do that.

There is no need to re-enable napi since we set the initialized
flag before calling ipoib_ib_dev_stop which will disable napi,
disabling napi twice is harmless in case it was already disabled.
One more reason for this fix is that when using IPoIB new device
driver napi is not added to priv, this can lead to kernel panic
when rn_ops ndo_open fails.
