When reading out a DDI config that uses a PLL that is not part of the
shared_dpll scheme (DPLL0), it's totally normal to end up in the
default: case of that switch.

According to "Cherryview_GFXclocks_y14w36d1.xlsx" the GPU frequency
divider should be 10 in when the CZ clock is 400 MHz. Change the code
to agree so that we report the correct frequencies.

Ebtables on the OUTPUT chain (NF_BR_LOCAL_OUT) would not work as expected
for both locally generated IGMP and MLD queries. The IP header specific
filter options are off by 14 Bytes for netfilter (actual output on
interfaces is fine).
NF_HOOK() expects the skb->data to point to the IP header, not the
ethernet one (while dev_queue_xmit() does not). Luckily there is an
br_dev_queue_push_xmit() helper function already - let's just use that.
Introduced by eb1d16414339a6e113d89e2cca2556005d7ce919
("bridge: Add core IGMP snooping support")
Ebtables example:
$ ebtables -I OUTPUT -p IPv6 -o eth1 --logical-out br0 \

We can only use page_address on memory that has been mapped using kmap,
when the buffer passed to the SPI has been allocated by vmalloc the page
has not necessarily been mapped through kmap. This means sometimes
page_address will return NULL causing the pointer we pass to sg_set_buf
to be invalid.
As we only call page_address so that we can pass a virtual address to
sg_set_buf which will then immediately call virt_to_page on it, fix this
by calling sg_set_page directly rather then relying on the sg_set_buf
helper.

The datasheet for PL330 says that the data buffer value in the CRD
register is 10bits wide. However, the value stored is "minus one",
which the driver corrects for. Maximum value that the data buffer
depth can have is 1024 lines, which requires 11 bits for storage.
While making updates I found printing the peripheral ID as a hex
value to be more useful as the datasheet shows the values that way.

The algorithm used for programming the DMA Controller doesn't take into
consideration the requirements of transfers that are not aligned to the
bus width. This failure may result in DMA transferring one too few MFIFO
entries (so too few bytes are copied) or the DMA trying to write one too
many MFIFO entries and hanging because this is never provided.
See "MFIFO Usage Overview" chapter in the the TRM for "CoreLink DMA
Controller DMA-330", Revision r1p1.
We work around these shortcomings by making sure we pick a burst size
and length which ensures no bursts straddle an MFIFO entry.

md_check_recovery will skip any recovery and also clear
MD_RECOVERY_NEEDED if MD_RECOVERY_FROZEN is set.
So when we clear _FROZEN, we must set _NEEDED and ensure that
md_check_recovery gets run.
Otherwise we could miss out on something that is needed.
In particular, this can make it impossible to remove a
failed device from an array is the 'recovery-needed' processing
didn't happen.
Suitable for stable kernels since 3.13.

mld_newpack() skb allocations are usually requested with dev->mtu
in size, since commit 72e09ad107e7 ("ipv6: avoid high order allocations")
we have changed the limit in order to be less likely to fail.
However, in MLD/IGMP code, we have some rather ugly AVAILABLE(skb)
macros, which determine if we may end up doing an skb_put() for
adding another record. To avoid possible fragmentation, we check
the skb's tailroom as skb->dev->mtu - skb->len, which is a wrong
assumption as the actual max allocation size can be much smaller.
The IGMP case doesn't have this issue as commit 57e1ab6eaddc
("igmp: refine skb allocations") stores the allocation size in
the cb[].
Set a reserved_tailroom to make it fit into the MTU and use
skb_availroom() helper instead. This also allows to get rid of
igmp_skb_size().

2) mdp4/hdmi/core bits for atomic helpers. Still missing mdp5

Pravin B Shelar says:
====================
Open vSwitch
Following fixes are accumulated in ovs-repo.
Three of them are related to protocol processing, one is
related to memory leak in case of error and one is to
fix race.
Patch "Validate IPv6 flow key and mask values" has conflicts
with net-next, Let me know if you want me to send the patch
for net-next.

Solves possible lockup issues that can be seen from firmware DCB agents calling
into the DCB app api.
DCB firmware event queues can be tied in with NAPI so that dcb events are
generated in softIRQ context. This can results in calls to dcb_*app()
functions which try to take the dcb_lock.
If the the event triggers while we also have the dcb_lock because lldpad or
some other agent happened to be issuing a get/set command we could see a cpu
lockup.
This code was not originally written with firmware agents in mind, hence
grabbing dcb_lock from softIRQ context was not considered.

In case of any failure ieee802154fake_probe() just calls unregister_netdev().
But it does not look safe to unregister netdevice before it was registered.
The patch implements straightforward resource deallocation in case of
failure in ieee802154fake_probe().
Found by Linux Driver Verification project (linuxtesting.org).

Pull SCSI fixes from James Bottomley:
"This is a set of six fixes and a MAINTAINER update.
The fixes are two multipath (one in Test Unit Ready handling for the
path checkers and one in the section of code that sends a start unit
after failover; both of these were perturbed by the scsi-mq update), a
CD-ROM door locking fix that was likewise introduced by scsi-mq and
three driver fixes for a previous code update in cxgb4i, megaraid_sas
and bnx2fc"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
bnx2fc: fix tgt spinlock locking
megaraid_sas: fix bug in handling return value of pci_enable_msix_range()
cxgb4i: send abort_rpl correctly
cxgbi: add maintainer for cxgb3i/cxgb4i
scsi: TUR path is down after adapter gets reset with multipath
scsi: call device handler for failed TUR command
scsi: only re-lock door after EH on devices that were reset

Register offsets have changed between a3xx and a4xx GPUs.
To be able access these registers in common code, we create
a lookup table, and set of read-write APIs to access the
register through the lookup table.

Use pre-computed iova when unmapping, to reduce the places we assume iova
and mmap offset are (at the moment) the same. And get rid of an extra
drm_gem_free_mmap_offset() call (since it is already called from
drm_gem_object_release())
