[ Upstream commit 7a55948d38eb9b274cbbdd56dc1dd4b96ebfbe04 ]

UUIDs are considered as metadata. __uuid_write should add the number
of buckets (in sectors) written to disk to ca->meta_sectors_written.
Currently only 1 bucket is used in uuid write.

Steps to test:
1) create a fresh backing device and a fresh cache device separately.
   The backing device didn't attach to any cache set.
2) cd /sys/block/<cache device>/bcache
   cat metadata_written      // record the output value
   cat bucket_size
3) attach the backing device to cache set
4) cat metadata_written
   The output value is almost the same as the value in step 2
   before the change.
   After the change, the value is bigger about 1 bucket size.

Calling of_node_put() decreases the reference count of a device tree
object, and may free some data.

However, the of_phandle_args structure embedding it is passed to
reset_controller_dev.of_xlate() after that, so it may still be accessed.

Move the call to of_node_put() down to fix this.

The framebuffer options and devices menu is unintentionally split
or broken because some items in it do not depend on FB (including
several under omap and mmp).
Fix this by moving FB_CMDLINE, FB_NOTIFY, and FB_CLPS711X_OLD to
just before the FB Kconfig symbol definition and by moving the
omap, omap2, and mmp menus to last, following FB_SM712.

Also, the FB_VIA dependencies are duplicated by both being inside
an "if FB_VIA/endif" block and "depends on FB_VIA", so drop the
"depends on FB_VIA" lines since they are redundant.

[ Upstream commit 60e5e48dba72c6b59a7a9c7686ba320766913368 ]

When a device tree set a display-timing using native-mode
then according to the bindings doc this should:

    native-mode:
    The native mode for the display, in case multiple
    modes are provided.
    When omitted, assume the first node is the native.

The atmel_lcdfb used the last timing subnode and did not
respect the timing mode specified with native-mode.

Introduce use of of_get_videomode() which allowed
a nice simplification of the code while also
added support for native-mode.

As a nice side-effect this fixes a memory leak where the
data used for timings and the display_np was not freed.

[ Upstream commit 541d7fdd7694560404c502f64298a90ffe017e6b ]

The AF_XDP socket struct can exist in three different, implicit
states: setup, bound and released. Setup is prior the socket has been
bound to a device. Bound is when the socket is active for receive and
send. Released is when the process/userspace side of the socket is
released, but the sock object is still lingering, e.g. when there is a
reference to the socket in an XSKMAP after process termination.

The Rx fast-path code uses the "dev" member of struct xdp_sock to
check whether a socket is bound or relased, and the Tx code uses the
struct xdp_umem "xsk_list" member in conjunction with "dev" to
determine the state of a socket.

However, the transition from bound to released did not tear the socket
down in correct order.

On the Rx side "dev" was cleared after synchronize_net() making the
synchronization useless. On the Tx side, the internal queues were
destroyed prior removing them from the "xsk_list".

This commit corrects the cleanup order, and by doing so
xdp_del_sk_umem() can be simplified and one synchronize_net() can be
removed.

since we replaced the image. However, now that there is a single

offload. Since driver re-sent the keys, the PN got zeroed and the
receiver dropped the next packets, until PN caught up again.

There was a small race when removing the sbshc module where
smbus_alarm() had queued acpi_smbus_callback() for deferred execution
but it hadn't been run yet, so that when it did run hc had been freed
and the module unloaded, resulting in an invalid paging request.

A similar race existed when removing the sbs module with regards to
acpi_sbs_callback() (which is called from acpi_smbus_callback()).

We therefore need to ensure no callbacks are pending or executing before
the cleanups are done and the modules are removed.

If a receive is in progress or starts before the transmit has
a chance, then lower the Signal Free Time of the upcoming transmit
to no more than CEC_SIGNAL_FREE_TIME_NEW_INITIATOR.

This is per the specification requirements.

Changing framerate right before streamon had no effect,
the new framerate value was taken into account only at
next streamon, fix this.

Running "./nfstest_delegation --runtest recall26" uncovers that
client doesn't recover the lock when we have an appending open,
where the initial open got a write delegation.

Instead of checking for the passed in open context against
the file lock's open context. Check that the state is the same.

log_first_seq and console_seq are 64-bit unsigned integers.
Correct a wrong casting that might cut off the output.

clk_notifier_register() documentation states, that the provided notifier
callbacks associated with the notifier must not re-enter into the clk
framework by calling any top-level clk APIs. Fix this by replacing
clk_get_rate() calls with clk_hw_get_rate(), which is safe in this
context.

The bit of GATE_BUS_PERIS1 for CLK_SECKEY is just reserved on
exynos5422/5800, not exynos5420. Define gate clk for exynos5420 to
handle the bit only on exynos5420.

SoC clock drivers should suspend after every other drivers in the system,
which are using clocks and resume before them. The last stage for calling
suspend device callbacks is NOIRQ stage and there exists driver, which use
that state (dwmmc-exynos), so Exynos5433 clocks driver should also use it.
During the same stage, clocks driver will be always suspended after its
clients as a direct result of proper device probe order (deferred probe
reorders the suspend call sequence).
