On AMD's SB800 and upwards, the SMBus is shared with the Integrated
Micro Controller (IMC).
The platform provides a hardware semaphore to avoid race conditions
among them. (Check page 288 of the SB800-Series Southbridges Register
Reference Guide http://support.amd.com/TechDocs/45482.pdf)
Without this patch, many access to the SMBus end with an invalid
transaction or even with the bus stalled.

drm: Convert all helpers to drm_connector_list_iter
and so we can drop this again.
This fixes a locking inversion on nouveau, where the rpm code needs to
re-enable. But in other places the rpm_get() calls are nested within
the big modeset locks.
While at it, also improve the kerneldoc for these two functions a
notch.
v2: Update the kerneldoc even more to explain that these functions
can't be called concurrently, or bad things happen (Chris).

a NFSv4.0 file. It seems possible that the state manager could try to
reclaim a lock and take a reference on the fl->fl_file at the same time the
file is being released if, during the close(), a signal interrupts the wait
for outstanding IO while removing locks which then skips the removal
of that lock.
Since 83bfff23e9 ("nfs4: have do_vfs_lock take an inode pointer") has
removed the need to traverse fl->fl_file->f_inode in nfs4_lock_done(),
taking that reference is no longer necessary.

When regulators are successfully registered, we check to see if the
regulator is a supply for any other registered regulator and if so
add the new regulator as the supply for the existing regulator(s).
Some devices, such as Power Management ICs, may register a series of
regulators when probed and there are cases where one of the regulators
may fail to register and defer the probing of the parent device. In this
case any successfully registered regulators would be unregistered so
that they can be re-registered at some time later when the probe is
attempted again. However, if one of the regulators that was registered
was added as a supply to another registered regulator (that did not
belong to the same parent device), then this supply regulator was
unregister again because the parent device is probe deferred, then a
regulator could be holding an invalid reference to a supply regulator
that has been unregistered. This will lead to a system crash if that
regulator is then used.
Although it would be possible to check when unregistering a regulator
if any other regulator in the system is using it as a supply, it still
may not be possible to remove it as a supply if this other regulator is
in use. Therefore, fix this by preventing any regulator from adding
another regulator as a supply if the parent device for the supply
regulator has not been bound and if the parent device for the supply
and the regulator are different. This will allow a parent device that is
registering regulators to be probe deferred and ensure that none of the
regulators it has registered are used as supplies for any other
regulator from another device.

The RDMA core uses ib_pack() to convert from unpacked CPU structs
to on-the-wire bitpacked structs.
This process requires that 1 bit fields are declared as u8 in the
unpacked struct, otherwise the packing process does not read the
value properly and the packed result is wired to 0. Several
places wrongly used int.
Crucially this means the kernel has never, set reversible
correctly in the path record request. It has always asked for
irreversible paths even if the ULP requests otherwise.
When the kernel is used with a SM that supports this feature, it
completely breaks communication management if reversible paths are
not properly requested.
The only reason this ever worked is because opensm ignores the
reversible bit.

ulseep_range() uses hrtimers and provides no advantage over msleep()
for larger delays. For this large delay msleep() is preferable.

ulseep_range() uses hrtimers and provides no advantage over msleep()
for larger delays. Fix up the 70/80ms delays here passing the "min"
value to msleep(). This reduces the load on the hrtimer subsystem.

These fixes address a number of issues in the ch341 driver and includes
a partial revert of a change in how we set the line settings that went
into 4.10-rc1 but which turned out to have undesired side effects. This
included deasserting the modem-control lines when configuring the
device, but also prevented a certain class of CH340 devices from working
with the driver.
Included are also two fixes for two minor information leaks in
kl5kusb105 and ch341 due to failures to detect short control transfers.

When dumping the VMA, include the parameters of the different GGTT views
so that we can distinguish them.
v2: Contract output and add MISSING_CASE for any unknown types.
v3: Show both stride and offset for rotated planes.

The internal object is a collection of struct pages and so is
intrinsically linked to the available physical memory on the machine,
and not an arbitrary type from the uabi. Use phys_addr_t so the link
between size and memory consumption is clear, and then double check that
we don't overflow the maximum object size.
v2: Also assert that size is not zero - a mistake I made a few times
while writing selftests.

Move the GuC invalidation of its ggtt TLB to where we perform the ggtt
modification rather than proliferate it into all the callers of the
insert (which may or may not in fact have to do the insertion).
v2: Just do the guc invalidate unconditionally, (afaict) it has no impact
without the guc loaded on gen8+
v3: Conditionally invalidate the guc - just in case that register has
not been validated for other modes.
