Pull radeon mullins support from Dave Airlie:
"This is support for the new AMD mullins APU, it pretty much just adds
support to the driver in the all the right places, and is pretty low
risk wrt other GPUs"
Oh well. I guess it ends up fitting under "support new hardware" for
merging late.

Without this this EEE PC exports a non working WMI interface, with this it
exports a working "good old" eeepc_laptop interface, fixing brightness control
not working as well as rfkill being stuck in a permanent wireless blocked
state.
This is not an ideal way to fix this, but various attempts to fix this
otherwise have failed, see:

In case RFKILL is in KILL position, the NIC will issue an
interrupt straight away. This interrupt won't be sent
because it is masked in the hardware.
But if our interrupt service routine is called for another
reason (SHARED_IRQ), then we'll look at the interrupt cause
and service it. This can cause bad things if we are not
ready yet.
Explicitly clean the interrupt cause register to make sure
we won't service anything before we are ready to.

The jme driver forgot to check the return status from pci_map_page in its tx

augment the tx path to tell the stack that the driver is busy so we re-queue the

When a ZPODD device is unbound via sysfs, the ACPI notify handler
is not removed. This causes panics as observed in Bug #74601. The
panic only happens when the wake happens from outside the kernel
(i.e. inserting a media or pressing a button). Add a loop to
ata_port_detach which loops through the port's devices and checks
if zpodd is enabled, if so call zpodd_exit.

The commit dbde5c29 "dw_dmac: use devm_* functions to simplify code" turns
probe function to use devm_* helpers and simultaneously brings a regression. We
need to ensure irq is disabled, followed by ensuring that don't schedule any
more tasklets and then its safe to use tasklet_kill().
The free_irq() will ensure that the irq is disabled and also wait till all
scheduled interrupts are executed by invoking synchronize_irq(). So we need to
only do tasklet_kill() after invoking free_irq().

3. Fix for the UVD command stream parser.
4. Fix for bootup UVD clocks on RV7xx systems.
5. Adding missing error check on dpcd reads.
6. Fixes number of banks calculation on SI.

If an md array with externally managed metadata (e.g. DDF or IMSM)
is in use, then we should not set safemode==2 at shutdown because:
1/ this is ineffective: user-space need to be involved in any 'safemode' handling,
2/ The safemode management code doesn't cope with safemode==2 on external metadata
and md_check_recover enters an infinite loop.
Even at shutdown, an infinite-looping process can be problematic, so this

16) Clamp delayed_ack in tcp_cubic to prevent theoretical divides by
zero. Fix from Liu Yu.

John Fastabend.
18) Properly reference the transport module when vsock_core_init() runs,
from Andy King.
19) Fix buffer overflow in cdc_ncm driver, from Bjørn Mork.
20) IP_ECN_decapsulate() doesn't see a correct SKB network header in
ip_tunnel_rcv(), fix from Ying Cai.

Under "heavy" RX load, the driver cannot handle the descriptors fast
enough. In detail, when a descriptor is consumed, its used flag is
cleared and once the RX budget is consumed all descriptors with a
cleared used flag are prepared to receive more data. Under load though,
the HW may constantly receive more data and use those descriptors with a
cleared used flag before they are actually prepared for next usage.
The head and tail pointers into the RX-ring should always be valid and
we can omit clearing and checking of the used flag.
