If port_guid is set with the default subnet_prefix, then we get a change
event and run a port refresh, we don't update the port_guid. As a
result, attempts to create a target device that uses the new
subnet_prefix in the wwn will fail to find a match and be rejected by
the ib_srpt driver. This makes it impossible to configure a port if it
was initialized with a default subnet_prefix and later changed to any
non-default subnet-prefix. Updating the port refresh task to always
update the wwn based upon the current subnext_prefix solves this
problem.

We pass xen_vcpu_id mapping information to hypercalls which require
uint32_t type so it would be cleaner to have it as uint32_t. The
initializer to -1 can be dropped as we always do the mapping before using
it and we never check the 'not set' value anyway.

After arbitrary bio size was introduced, the incoming bio may
be very big. We have to split the bio into small bios so that
each holds at most BIO_MAX_PAGES bvecs for safety reason, such
as bio_clone().

nvme_set_features() callers seem to expect that passing NULL as the
result pointer is acceptable. Teach nvme_set_features() not to try to
write to the NULL address.
For symmetry, make the same change to nvme_get_features(), despite the
fact that all current callers pass a valid result pointer.
I assume that this bug hasn't been reported in practice because
the callers that pass NULL are all in the SCSI translation layer
and no one uses the relevant operations.

The MIPI DSI output on Tegra SoCs requires some external logic to
calibrate the MIPI pads before a video signal can be transmitted. This
MIPI calibration logic requires to be powered on while the MIPI pads are
being used, which is currently done as part of the DSI driver's probe
implementation.
This is suboptimal because it will leave the MIPI calibration logic
powered up even if the DSI output is never used.
On Tegra114 and earlier this behaviour also causes the driver to hang
while trying to power up the MIPI calibration logic because the power
partition that contains the MIPI calibration logic will be powered on
by the display controller at output pipeline configuration time. Thus
the power up sequence for the MIPI calibration logic happens before
it's power partition is guaranteed to be enabled.
Fix this by splitting up the API into a request/free pair of functions
that manage the runtime dependency between the DSI and the calibration
modules (no registers are accessed) and a set of enable, calibrate and
disable functions that program the MIPI calibration logic at points in
time where the power partition is really enabled.
While at it, make sure that the runtime power management also works in
ganged mode, which is currently also broken.

When tearing down an AUX buf for an event via perf_mmap_close(),
__perf_event_output_stop() is called on the event's CPU to ensure that
trace generation is halted before the process of unmapping and
freeing the buffer pages begins.
The callback is performed via cpu_function_call(), which ensures that it
runs with interrupts disabled and is therefore not preemptible.
Unfortunately, the current code grabs the per-cpu context pointer using
get_cpu_ptr(), which unnecessarily disables preemption and doesn't pair
the call with put_cpu_ptr(), leading to a preempt_count() imbalance and
a BUG when freeing the AUX buffer later on:

The ARM architected timer driver falls under the drivers/clocksource/

number of people who should be Cc'd.
The ARM architected timer is a core component of ARMv7+VE and ARMv8, and
is critical to the correct operation of both architecture ports (and
their respective KVM code), and patches to it should have review by
knowledgeable interested parties.
This patch adds a MAINTAINERS entry for the driver and its low-level

It was reported that hibernation could fail on the 2nd attempt, where the
system hangs at hibernate() -> syscore_resume() -> i8237A_resume() ->
claim_dma_lock(), because the lock has already been taken.
However there is actually no other process would like to grab this lock on
that problematic platform.
Further investigation showed that the problem is triggered by setting
/sys/power/pm_trace to 1 before the 1st hibernation.
Since once pm_trace is enabled, the rtc becomes unmeaningful after suspend,
and meanwhile some BIOSes would like to adjust the 'invalid' RTC (e.g, smaller
than 1970) to the release date of that motherboard during POST stage, thus
after resumed, it may seem that the system had a significant long sleep time
which is a completely meaningless value.
Then in timekeeping_resume -> tk_debug_account_sleep_time, if the bit31 of the
sleep time happened to be set to 1, fls() returns 32 and we add 1 to
sleep_time_bin[32], which causes an out of bounds array access and therefor
memory being overwritten.
As depicted by System.map:
0xffffffff81c9d080 b sleep_time_bin
0xffffffff81c9d100 B dma_spin_lock
the dma_spin_lock.val is set to 1, which caused this problem.
This patch adds a sanity check in tk_debug_account_sleep_time()
to ensure we don't index past the sleep_time_bin array.
[jstultz: Problem diagnosed and original patch by Chen Yu, I've solved the
issue slightly differently, but borrowed his excelent explanation of the
issue here.]

When I added some extra sanity checking in timekeeping_get_ns() under
CONFIG_DEBUG_TIMEKEEPING, I missed that the NMI safe __ktime_get_fast_ns()
method was using timekeeping_get_ns().
Thus the locking added to the debug checks broke the NMI-safety of
__ktime_get_fast_ns().
This patch open-codes the timekeeping_get_ns() logic for
__ktime_get_fast_ns(), so can avoid any deadlocks in NMI.

We can't initialize the list head on deletion as this causes the node to

The list initialization was trying to fix a bug from multiple calls to

/usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o):
defined in discarded section `.text.exit' of
/usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o)
Apparently UML doesn't want to discard exit text, so let's place all EXIT_TEXT
sections in .exit.text.

UBIFS uses full names to work with xattrs, therefore we have to use
xattr_full_name() to obtain the xattr prefix as string.

An assertion in layout_in_gaps() verifies that the gap_lebs pointer is
below the maximum bound. When computing this maximum bound the idx_lebs
count is multiplied by sizeof(int), while C pointers arithmetic does take
into account the size of the pointed elements implicitly already. Remove
the multiplication to fix the assertion.

By representing each edge as its own device the channels are no longer
tied to being parented by the same smd device and as such an edge can
live as children of e.g. remoteproc instances.

The code exectued by the interrupt handler depends on the values parsed
after requesting the irq, just to be save we should therefor move the
request_irq() call to be done after parsing the properties.

Multi-channel clients split between several drivers need a way to close
individual channels, as these drivers might be removed individually.
With this in place the responsibility of closing additionally opened
channels to the client as well only concerning smd about the primary
channel.
With this approach we will only trigger removal of SMD devices based on
the state of the primary channel, however we get in sync with how rpmsg
works.

The Kconfig currently controlling compilation of this code is:
drivers/firmware/Kconfig:config QCOM_SCM
drivers/firmware/Kconfig: bool
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
