d7be295243 usb: dwc3: gadget: re-factor ->udc_start and ->udc_stop
we will be re-using it for suspend/resume, so
instead of duplicating code, let's just re-factor
the functions so they can be re-used.

5185c91385 usb: gadget: net2280: add USB2380 support
The PLX USB2380 is a PCIe version of the NET2280 and behaves more like the
USB338x but without the USB3.0 superspeed support.

This was tested with g_ether, g_serial, g_mass_storage on a Gateworks
Ventana GW2383.

d8877fc7e7 usb: gadget: storage: increase maximum storage num buffers
With a default size of 16kiB and with maximum of 32
buffers, we can transfer up to 512kiB, however Linux
can transfer up to 1MiB in a single mass storage
block transfer to USB3 storage devices.

Because of this, 1MiB block transfers end up being
slower than 512kiB block transfers. Let's increase
maximum number of storage buffers to a ridiculous
amount (256) so that anybody wanting to test maximum
achievable throughput can do so.

So I _should_ have looked at other unserialized users of ->load_avg,
but alas. Luckily nikbor reported a similar /0 from task_h_load() which
instantly triggered recollection of this here problem.

Aside from the intermediate value hitting memory and causing problems,
there's another problem: the underflow detection relies on the signed
bit. This reduces the effective width of the variables, IOW its
effectively the same as having these variables be of signed type.

This patch changes to a different means of unsigned underflow
detection to not rely on the signed bit. This allows the variables to
use the 'full' unsigned range. And it does so with explicit LOAD -
STORE to ensure any intermediate value will never be visible in
memory, allowing these unserialized loads.

Note: GCC generates crap code for this, might warrant a look later.

Note2: I say 'full' above, if we end up at U*_MAX we'll still explode;
       maybe we should do clamping on add too.

At high bus load it could happen that "at91_poll()" enters with all RX
message boxes filled up. If then at the end the "quota" is exceeded as
well, "rx_next" will not be reset to the first RX mailbox and hence the
interrupts remain disabled.

427460c83c can: c_can: Update D_CAN TX and RX functions to 32 bit - fix Altera Cyclone access
When testing CAN write floods on Altera's CycloneV, the first 2 bytes
are sometimes 0x00, 0x00 or corrupted instead of the values sent. Also
observed bytes 4 & 5 were corrupted in some cases.

The D_CAN Data registers are 32 bits and changing from 16 bit writes to
32 bit writes fixes the problem.

Testing performed on Altera CycloneV (D_CAN).  Requesting tests on other
C_CAN & D_CAN platforms.

Driver has 2 sets of entries for handling ramrod configurations
toward firmware - a regular pre-allocated set of entires and a
possible 'unlimited' list of additional pending entries.

In most scenarios the 'unlimited' list would not be used, but
when it does the handling of the ramrod completion doesn't
properly handle the release of the entry.

326439883e qed: Prevent VF from Tx-switching 'promisc'
Internal loopback in driver is based on two things - first
is the willingness of transmitter to use it [in case of VFs,
this can be forced based on VEPA/VEB] and secondly on another
vport classification configuration which should match the
packet's destination.

Current code allows non-linux VFs to configure a 'promisc'
mode on Tx, meaning all traffic sent by VF would be loopbacked
internally by firmware; This isn't considered a valid mode and
as such should be prevented by PF.

Commit a6f75aa161 ("drm/exynos: fimd: add HW trigger support") added
hardware trigger support to the FIMD controller driver. But this broke
the display in at least the Exynos5800 Peach Pi Chromebook.

So until the issue is fixed, avoid using HW trigger for the Exynos5420
based boards and use SW trigger as it was before the mentioned commit.

d90efc9ee0 drm/exynos: dp: Fix NULL pointer dereference due uninitialized connector
Commit 3424e3a4f8 ("drm: bridge: analogix/dp: split exynos dp driver to
bridge directory") split the Exynos DP core driver into a core driver and
a bridge driver for the Analogix chip since that is also used by Rockchip.

But the change introduced a regression causing a NULL pointer dereference
when trying to access an uninitialized connector in the driver .get_modes:

Fix this by instead of having a connector struct for both the Exynos and
Analogix drivers, just use the connector initialized in the bridge driver.

Fixes: 3424e3a4f8 ("drm: bridge: analogix/dp: split exynos dp driver to bridge directory")

0e289e534a ARM: dts: STi: stih407-family: Disable reserved-memory co-processor nodes
This patch fixes a non-booting issue in Mainline.

When booting with a compressed kernel, we need to be careful how we
populate memory close to DDR start.  AUTO_ZRELADDR is enabled by default
in multi-arch enabled configurations, which place some restrictions on
where the kernel is placed and where it will be uncompressed to on boot.

AUTO_ZRELADDR takes the decompressor code's start address and masks out
the bottom 28 bits to obtain an address to uncompress the kernel to
(thus a load address of 0x42000000 means that the kernel will be
uncompressed to 0x40000000 i.e. DDR START on this platform).

Even changing the load address to after the co-processor's shared memory
won't render a booting platform, since the AUTO_ZRELADDR algorithm still
ensures the kernel is uncompressed into memory shared with the first
co-processor (0x40000000).

Another option would be to move loading to 0x4A000000, since this will
mean the decompressor will decompress the kernel to 0x48000000. However,
this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of
memory would essentially be wasted for no good reason.

Until we can work with ST to find a suitable memory location to
relocate co-processor shared memory, let's disable the shared memory
nodes.  This will ensure a working platform in the mean time.

NB: The more observant of you will notice that we're leaving the DMU
shared memory node enabled; this is because a) it is the only one in
active use at the time of this writing and b) it is not affected by
the current default behaviour which is causing issues.

2744d2fde0 hwmon: (dell-smm) Disallow fan_type() calls on broken machines
Some Dell machines have especially broken SMM or BIOS which cause that once
fan_type() is called then CPU fan speed going randomly up and down. And for
fixing this behaviour reboot is required.

So this patch creates fan_type blacklist of affected Dell machines and
disallow fan_type() call on them to prevent that erratic behaviour.

Old blacklist which disabled loading driver on some machines added in
commits a4b45b25f1 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100")
and 6220f4ebd7 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8000") were
moved to FAN_TYPE blacklist.

7613663cc1 hwmon: (dell-smm) Restrict fan control and serial number to CAP_SYS_ADMIN by default
For security reasons ordinary user must not be able to control fan speed
via /proc/i8k by default. Some malicious software running under "nobody"
user could be able to turn fan off and cause HW problems. So this patch
changes default value of "restricted" parameter to 1.

Also restrict reading of DMI_PRODUCT_SERIAL from /proc/i8k via "restricted"
parameter. It is because non root user cannot read DMI_PRODUCT_SERIAL from
sysfs file /sys/class/dmi/id/product_serial.

Old non secure behaviour of file /proc/i8k can be achieved by loading this
module with "restricted" parameter set to 0.

Note that this patch has effects only for kernels compiled with CONFIG_I8K
and only for file /proc/i8k. Hwmon interface provided by this driver was
not changed and root access for setting fan speed was needed also before.

d9e66146c1 ACPI fix for v4.7-rc4
Revert a recent ACPICA commit that introduced a suspend-to-RAM
 regression on one system due to incorrect information in its ACPI
 tables that had not been taken into consideration at all before (and
 everything worked), but the commit in question started to use it.

3bb549ae4c RDS: TCP: rds_tcp_accept_one() should transition socket from RESETTING to UP
The state of the rds_connection after rds_tcp_reset_callbacks() would
be RDS_CONN_RESETTING and this is the value that should be passed
by rds_tcp_accept_one()  to rds_connect_path_complete() to transition
the socket to RDS_CONN_UP.

a9836cbb5f net: tilegx: use correct timespec64 type
The conversion to the 64-bit time based ptp methods left two instances
of 'struct timespec' in place. This is harmless because 64-bit
architectures define timespec64 as timespec, and this driver is
not used on 32-bit machines.

However, using 'struct timespec64' directly is obviously the right
thing to do, and will help us remove 'struct timespec' in the future.
