Pull rdma fixes from Doug Ledford:
"Three late 4.4-rc fixes.
The first two were very small in terms of number of lines, the third
is more lines of change than I like this late in the cycle, but there
are positive test results from Avagotech and from my own test setup
with the target hardware, and given the problem was a 100% failure
case, I sent it through.
- A previous patch updated the mlx4 driver to use vmalloc when there
was not enough memory to get a contiguous region large enough for
our needs, so we need kvfree() whenever we free that item. We
missed one place, so fix that now.
- A previous patch added code to match incoming packets against a
specific device, but failed to compensate for devices that have
both InfiniBand and Ethernet ports. Fix that.
- Under certain vlan conditions, the ocrdma driver would fail to
bring up any vlan interfaces and would print out a circular locking
failure. Fix that"

If null_blk is run in NULL_IRQ_TIMER mode and with queue_mode NULL_Q_RQ,
we need to restart the queue from the hrtimer interrupt. We can't

Recently Dough Ledford reported a deadlock happening
between ocrdma-load sequence and NetworkManager service
issueing "open" on be2net interface.
The deadlock happens when any be2net hook (e.g. open/close) is called
in parallel to insmod ocrdma.ko.
A. be2net is sending administrative open/close event to ocrdma holding
device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net.
So sequence of locks is rtnl_lock---> device_list lock
B. When new ocrdma roce device gets registered, infiniband stack now
takes rtnl_lock in ib_register_device() in GID initialization routines.
So sequence of locks in this path is device_list lock ---> rtnl_lock.
This improper locking sequence causes deadlock.
In order to resolve the above deadlock condition, ocrdma intorduced a
patch to stop listening to administrative open/close events generated from
be2net driver. It now depends on link-state-change async-event generated from
CNA. This change leaves behind dead code which used to generate administrative
open/close events. This patch cleans-up all that dead code from be2net.

With this patch we stop using administrative open and close events
injected by be2net driver. These events were used to dispatch PORT_ACTIVE
and PORT_ERROR events to the IB-stack. This patch implements a logic
to receive async-link-events generated from CNA whenever link-state-change
is detected. Now on, these async-events will be used to dispatch
PORT_ACTIVE and PORT_ERROR events to IB-stack.
Depending on async-events from CNA removes the need to hold device-list-mutex
and thus breaks the busy-wait scenario.

Doug reports that the equivalent page allocator on 32-bit ARM exhibits
particularly pathalogical behaviour under memory pressure when
fragmentation is high, where allocating a 4MB buffer takes tens of
seconds and the number of calls to alloc_pages() is over 9000![1]
We can drastically improve that situation without losing the other
benefits of high-order allocations when they would succeed, by assuming
memory pressure is relatively constant over the course of an allocation,
and not retrying allocations at orders we know to have failed before.
This way, the best-case behaviour remains unchanged, and in the worst
case we should see at most a dozen or so (MAX_ORDER - 1) failed attempts
before falling back to single pages for the remainder of the buffer.

Allow the the driver to change the clock supplied from the CAR directly,
minimizing the need to divide the clock inside the SDMMC module itself.
This allows for higher clock speeds than the default 48MHz supplied to
the module and is a prerequisite to support DDR signaling modes, where
the Tegra host needs to be run with a fixed internal divider of 2 for
data to be sampled correctly. (Tegra K1 TRM v03p chapter 29.7.1.1)
Also enable the broken preset value quirk as the preset values need to
be adapted to the changed clocking. While Tegra114+ allows this through
vendor registers, there is no such way for Tegra30. Takes the easy way
out and keep things consistent between the different SoC generations by
flagging the preset registers as unusable.

After commit 52221610dd84 ("mmc: sdhci: Improve external VDD regulator
support"), for the VDD is supplied via external regulators, we ignore
the code to convert a VDD voltage request into one of the standard
SDHCI voltage levels, then program it in the SDHCI_POWER_CONTROL. This
brings two issues:
1. SDHCI_QUIRK2_CARD_ON_NEEDS_BUS_ON quirk isn't handled properly any
more.
2. What's more, once SDHCI_POWER_ON bit is set, some controllers such
as the sdhci-pxav3 used in marvell berlin SoCs require the voltage
levels programming in the SDHCI_POWER_CONTROL register, even the VDD
is supplied by external regulator. So the host in marvell berlin SoCs
still works fine after the commit. However, commit 3cbc6123a93d ("mmc:
sdhci: Set SDHCI_POWER_ON with external vmmc") sets the SDHCI_POWER_ON
bit, this would make the host in marvell berlin SoCs won't work any
more with external vmmc.
This patch restores the behavior when setting VDD through external
regulator by moving the call of mmc_regulator_set_ocr() to the end
of sdhci_set_power() function.
After this patch, the sdcard on Marvell Berlin SoC boards work again.

It is quite common for Android devices to utilize more
then 8 partitions on internal eMMC storage.
The vanilla kernel can support this via
CONFIG_MMC_BLOCK_MINORS, however that solution caps the
system to 256 minors total, which limits the number of
mmc cards the system can support.
This patch, which has been carried for quite awhile in
the AOSP common tree, provides an alternative solution
that doesn't seem to limit the total card count. So I
wanted to submit it for consideration upstream.
This patch sets the GENHD_FL_EXT_DEVT flag, which will
allocate minor number in major 259 for partitions past
disk->minors.
It also removes the use of disk_devt to determine devidx
from md->disk. md->disk->first_minor is always initialized
from devidx and can always be used to recover it.

The mmc workqueue is an ordered workqueue, allowing only one work to
execute per given time. As this workqueue is used for card detection, the
conseqeunce is that cards will be detected one by one waiting for each
other.
Moreover, most of the time spent during card initialization is waiting for
the card's internal firmware to be ready. From a CPU perspective this
typically means waiting for a completion variable to be kicked via an
IRQ-handler or waiting for a sleep timer to finish.
This behaviour of detecting/initializing cards is sub-optimal, especially
for SOCs having several controllers/cards.
Let's convert to use the system_freezable_wq for the mmc detect works.
This enables several works to be executed simultaneously and thus also
cards to be detected like so.
Tests on UX500, which holds two eMMC cards and an SD-card (actually also
an SDIO card, currently not detected), shows a significant improved
behaviour due to this change.
Before this change, both the eMMC cards waited for the SD card to be
initialized as its detect work entered the workqueue first. In some cases,
depending on the characteristic of the SD-card, they got delayed 1-1.5 s.
Additionally for the second eMMC, it needed to wait for the first eMMC to
be initialized which added another 120-190 ms.
Converting to the system_freezable_wq, removed these delays and made both
the eMMC cards available far earlier in the boot sequence.
Selecting the system_freezable_wq, in favour of for example the system_wq,
is because we need card detection mechanism to be disabled once userspace
are frozen during system PM. Currently the mmc core deal with this via PM
notifiers, but following patches may utilize the behaviour of the
system_freezable_wq, to simplify the use of the PM notifiers.

We need to keep track of all resources, such as rx rings, tx rings,

We adjust all max resources in struct bnxt_pf_info after they have been
assigned to the VFs. There is no need to keep the separate
max_pf_tx_rings and max_pf_rx_rings.
When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the
max resources for the PF.

The hardware resources required to enable NTUPLE varies depending on
how many rx channels are configured. We need to make sure we have the
resources before we enable NTUPLE. Add bnxt_rfs_capable() to do the
checking.
In addition, we need to do the same checking in ndo_fix_features(). As
the rx channels are changed using ethtool -L, we call
netdev_update_features() to make the necessary adjustment for NTUPLE.
Calling netdev_update_features() in netif_running() state but before
calling bnxt_open_nic() would be a problem. To make this work,
bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for
the true hardware state instead of checking netif_running().

simplified sharing of networking interfaces and accelerators
by multiple CPU cores and the accelerators.
One of the DPAA accelerators is the Frame Manager (FMan)
which contains a series of hardware blocks: ports, Ethernet MACs,
a multi user RAM (MURAM) and Storage Profile (SP).
This patch set introduce the FMan drivers.
Each driver configures and initializes the corresponding
FMan hardware module (described above).
The MAC driver offers support for three different
types of MACs (eTSEC, TGEC, MEMAC).
