When rpm_resume() desactivates the autosuspend timer, it should only
try to cancel hrtimer but not wait for the handler to finish, because
both rpm_resume() and pm_suspend_timer_fn() take the power.lock.
A deadlock is possible as follows:
CPU0 CPU1
rpm_resume()
spin_lock_irqsave
pm_suspend_timer_fn()
spin_lock_irqsave
pm_runtime_deactivate_timer()
hrtimer_cancel()
It is sufficient to call hrtimer_try_to_cancel() from
pm_runtime_deactivate_timer(), because dev->power.timer_expires
reset to 0 by it, so use that function instead of hrtimer_cancel().

Several u->addr and u->path users are not holding any locks in
common with unix_bind(). unix_state_lock() is useless for those
purposes.
u->addr is assign-once and *(u->addr) is fully set up by the time
we set u->addr (all under unix_table_lock). u->path is also
set in the same critical area, also before setting u->addr, and
any unix_sock with ->path filled will have non-NULL ->addr.
So setting ->addr with smp_store_release() is all we need for those
"lockless" users - just have them fetch ->addr with smp_load_acquire()
and don't even bother looking at ->path if they see NULL ->addr.
Users of ->addr and ->path fall into several classes now:
1) ones that do smp_load_acquire(u->addr) and access *(u->addr)
and u->path only if smp_load_acquire() has returned non-NULL.
2) places holding unix_table_lock. These are guaranteed that
*(u->addr) is seen fully initialized. If unix_sock is in one of the
"bound" chains, so's ->path.
3) unix_sock_destructor() using ->addr is safe. All places
that set u->addr are guaranteed to have seen all stores *(u->addr)
while holding a reference to u and unix_sock_destructor() is called
when (atomic) refcount hits zero.
4) unix_release_sock() using ->path is safe. unix_bind()
is serialized wrt unix_release() (normally - by struct file
refcount), and for the instances that had ->path set by unix_bind()
unix_release_sock() comes from unix_release(), so they are fine.
Instances that had it set in unix_stream_connect() either end up
attached to a socket (in unix_accept()), in which case the call
chain to unix_release_sock() and serialization are the same as in
the previous case, or they never get accept'ed and unix_release_sock()
is called when the listener is shut down and its queue gets purged.
In that case the listener's queue lock provides the barriers needed -
unix_stream_connect() shoves our unix_sock into listener's queue
under that lock right after having set ->path and eventual
unix_release_sock() caller picks them from that queue under the
same lock right before calling unix_release_sock().
5) unix_find_other() use of ->path is pointless, but safe -
it happens with successful lookup by (abstract) name, so ->path.dentry
is guaranteed to be NULL there.

[Why]
When a dce80 asic was suspended, the clocks were not set to 0.
Upon resume, the new clock was compared to the existing clock,
they were found to be the same, and so the clock was not set.
This resulted in a blackscreen.

In atomic commit, check to see if there are any active pipes.
If no, set clocks to 0

[Why]
If the cursor pos passed from DM is less than the plane_state->dst_rect
top left corner then the unsigned cursor pos wraps around to a large
positive number since cursor pos is a u32.
There was an attempt to guard against this in hubp1_cursor_set_position
by checking the src_x_offset and src_y_offset and offseting the
cursor hotspot within hubp1_cursor_set_position.
However, the cursor position itself is still being programmed
incorrectly as a large value.
This manifests itself visually as the cursor disappearing or containing
strange artifacts near the middle of the screen on raven.
[How]
Don't subtract the destination rect top left corner from the pos but
add it to the hotspot instead. This happens before the pos gets
passed into hubp1_cursor_set_position.
This achieves the same result but avoids the subtraction wrap around.
With this fix the original cursor programming logic can be used again.

When a DSA port is added to a bridge and brought up, the resulting STP
state programmed into the hardware depends on the order that these
operations are performed. However, the Linux bridge code believes that
the port is in disabled mode.
If the DSA port is first added to a bridge and then brought up, it will
be in blocking mode. If it is brought up and then added to the bridge,
it will be in disabled mode.
This difference is caused by DSA always setting the STP mode in
dsa_port_enable() whether or not this port is part of a bridge. Since
bridge always sets the STP state when the port is added, brought up or
taken down, it is unnecessary for us to manipulate the STP state.
Apparently, this code was copied from Rocker, and the very next day a
similar fix for Rocker was merged but was not propagated to DSA. See
e47172ab7e41 ("rocker: put port in FORWADING state after leaving bridge")

Commit 482997699ef0 ("ARM: tegra: Fix unit_address_vs_reg DTC warnings
for /memory") inadventently broke device tree ABI by adding a unit-
address to the "/memory" node because the device tree compiler flagged
the missing unit-address as a warning.
Tegra124 Chromebooks (a.k.a. Nyan) use a bootloader that relies on the
full name of the memory node in device tree being exactly "/memory". It
can be argued whether this was a good decision or not, and some other
bootloaders (such as U-Boot) do accept a unit-address in the name of the
node, but the device tree is an ABI and we can't break existing setups
just because the device tree compiler considers it bad practice to omit
the unit-address nowadays.
This partially reverts the offending commit and restores device tree ABI
compatibility.

On HP ProBook 4540s, if PM-runtime is enabled in the radeon driver
and the direct-complete optimization is used for the radeon device
during system-wide suspend, the system doesn't resume.
Preventing direct-complete from being used with the radeon device by
setting the DPM_FLAG_NEVER_SKIP driver flag for it makes the problem
go away, which indicates that direct-complete is not safe for the
radeon driver in general and should not be used with it (at least
for now).
This fixes a regression introduced by commit c62ec4610c40
("PM / core: Fix direct_complete handling for devices with no
callbacks") which allowed direct-complete to be applied to
devices without PM callbacks (again) which in turn unlocked
direct-complete for radeon on HP ProBook 4540s.

but did it incorrectly for a number of boards: armada-xp-gp,
armada-xp-db and armada-xp-lenovo-ix4-300d. Due to this, the NAND is
no longer detected on those platforms.
This commit fixes that by properly using the new NAND DT binding. This
commit was runtime-tested on Armada XP GP, the two other platforms are
only compile-tested.

We are saving the status of EEE even before we try to enable it. This
leads to a race with XMIT function that tries to arm EEE timer before we
set it up.
Fix this by only saving the EEE parameters after all operations are
performed with success.

The ll2 forwards all syn packets to the driver without validating the mac

The assumption that the maximum size of a syn packet is 128 bytes
is wrong. Tunneling headers were not accounted for.
Allocate buffers large enough for mtu.

The compound IOMMU group rework moved iommu_register_group() together
in pnv_pci_ioda_setup_iommu_api() (which is a part of
ppc_md.pcibios_fixup). As the result, pnv_ioda_setup_bus_iommu_group()
does not create groups any more, it only adds devices to groups.
This works fine for boot time devices. However IOMMU groups for
SRIOV's VFs were added by pnv_ioda_setup_bus_iommu_group() so this got
broken: pnv_tce_iommu_bus_notifier() expects a group to be registered
for VF and it is not.
This adds missing group registration and adds a NULL pointer check
into the bus notifier so we won't crash if there is no group, although
it is not expected to happen now because of the change above.
Example oops seen prior to this patch:

Commit 8099b047ecc4 ("exec: load_script: don't blindly truncate
shebang string") was trying to protect against a confused exec of a
truncated interpreter path. However, it was overeager and also refused
to truncate arguments as well, which broke userspace, and it was
reverted. This attempts the protection again, but allows arguments to
remain truncated. In an effort to improve readability, helper functions
and comments have been added.

Syzbot found out that running BPF_PROG_TEST_RUN with repeat=0xffffffff
makes process unkillable. The problem is that when CONFIG_PREEMPT is
enabled, we never see need_resched() return true. This is due to the
fact that preempt_enable() (which we do in bpf_test_run_one on each
iteration) now handles resched if it's needed.
Let's disable preemption for the whole run, not per test. In this case
we can properly see whether resched is needed.
Let's also properly return -EINTR to the userspace in case of a signal
interrupt.
See recent discussion:
http://lore.kernel.org/netdev/CAH3MdRWHr4N8jei8jxDppXjmw-Nw=puNDLbu1dQOFQHxfU2onA@mail.gmail.com
I'll follow up with the same fix bpf_prog_test_run_flow_dissector in
bpf-next.
