7eb1c496f7 drm/i915: Reject opening of pipe crc files for invalid pipes
We don't init the lock nor set up all the other state. And it doesn't
make sense anyway.

This appeases lockdep when running the igt/drv_debugfs_reader test.

565ee3897f drm/i915: do not save/restore backlight registers in KMS
The backlight enable code now has the smarts to do the right thing. Only
do backlight register save/restore in UMS.

Some VLV specific code gets dropped as UMS is not supported on VLV.

v2: Move save/restore to UMS instead of removing completely (Daniel).

    drm/i915: quirk no PCH_PWM_ENABLE for Dell XPS13 backlight

without really digging into what was going on.

Also, as mentioned in the related bug [1], having the quirk regressed
some of the machines it was supposed to fix to begin with, and there
were patches posted to disable the quirk on such machines [2]!

The fact is, we do need the BLM_PCH_PWM_ENABLE bit set to have
backlight. With the quirk, we've relied on BIOS to have set it, and our
save/restore code to retain it. With the full backlight setup at enable,
we have no place for things that rely on previous state.

With the per platform hooks, we've also made a change in the PCH
platform enable order: setting the backlight duty cycle between CPU and
PCH PWM enable. Some experimenting and

indicate that we can't set the backlight before enabling CPU PWM; the
value just won't stick. But AFAICT we should do it before enabling the
PCH PWM.

Finally, any fallout we should fix properly, preferrably without quirks,
and absolutely without quirks that rely on existing state. With the per
platform hooks have much more flexibility to adjust the sequence as
required by platforms.

f3db3f4389 ARM: 7885/1: Save/Restore 64-bit TTBR registers on LPAE suspend/resume
LPAE enabled kernels use the 64-bit version of TTBR0 and TTBR1
registers. If we're running an LPAE kernel, fill the upper half
of TTBR0 with 0 because we're setting it to the idmap here (the
idmap is guaranteed to be < 4Gb) and fully restore TTBR1 instead
of just restoring the lower 32 bits. Failure to do so can cause
failures on resume from suspend when these registers are only
half restored.

139cc2ba74 ARM: 7882/1: mm: fix __phys_to_virt to work with 64 bit phys_addr_t in BE case
Make sure that inline assembler that expects 'r' operand
receives 32 bit value.

Before this fix in case of CONFIG_ARCH_PHYS_ADDR_T_64BIT and
CONFIG_ARM_PATCH_PHYS_VIRT __phys_to_virt function passed 64 bit
value to __pv_stub inline assembler where 'r' operand is
expected. Compiler behavior in such case is not well specified.
It worked in little endian case, but in big endian case
incorrect code was generated, where compiler confused which
part of 64 bit value it needed to modify. For example BE
snippet looked like this:

N:0x80904E08 : MOV      r2,#0
N:0x80904E0C : SUB      r2,r2,#0x81000000

when LE similar code looked like this

N:0x808FCE2C : MOV      r2,r0
N:0x808FCE30 : SUB      r2,r2,#0xc0, 8 ; #0xc0000000

Note 'r0' register is va that have to be translated into phys

To avoid this situation use explicit cast to 'unsigned long',
which explicitly discard upper part of phys address and convert
value to 32 bit. Also add comment so such cast will not be
removed in the future.

3a2ffb65ee drm/i915/bdw: Limit GTT to 2GB
Because of the way in which we're allocating the pages for the Aliasing
PPGTT, we cannot actually successfully alloc enough space for anything
greater than 2GB.

Instead of a quick hack to fix this, we should defer until we have the
real solution in place (allocating much less contiguous space).

This wasn't found sooner because we didn't not have any systems
supporting more than a 2GB GTT.

f8e100621b drm/i915/bdw: GEN8 backlight support
Prior to Haswell the CPU control register for backlight
(BLC_PWM_CPU_CTL) toggled the PCH baclight pin for us. This made some
sense as there was no pin on the CPU. With Haswell came the introduction
of a CPU backlight pin, but the interface was still controlled by
software with the same mechnism. Behind the scenes, hardware did all the
dirty work for us.

Broadwell no longer provides this for free. If we want to use the PCH
backlight pin [1] then we have to set the override bit BLC_PWM_PCH_CTL1
and program BLC_PWM_PCH_CTL2 for the PWM values.

This patch implements that. This patch is compile tested only, and given
that I rarely if ever touch this code, careful review is welcome.

[1] According to Art, we know of no devices that exist which use the CPU
pin (and remember it has existed already on HSW). If such a device does
exist, we'll have to handle it properly - this is left as TODO until
then.

v2: Drop the abstraction prep patch, as a bigger backlight overhaul is
    in the works, and do just the mimimal bdw enabling now. (by Jani)

81b9eab5eb core/dev: do not ignore dmac in dev_forward_skb()
commit 06a23fe31c
("core/dev: set pkt_type after eth_type_trans() in dev_forward_skb()")
and refactoring 64261f230a
("dev: move skb_scrub_packet() after eth_type_trans()")

are forcing pkt_type to be PACKET_HOST when skb traverses veth.

which means that ip forwarding will kick in inside netns
even if skb->eth->h_dest != dev->dev_addr

Fix order of eth_type_trans() and skb_scrub_packet() in dev_forward_skb()
and in ip_tunnel_rcv()

Fixes: 06a23fe31c ("core/dev: set pkt_type after eth_type_trans() in dev_forward_skb()")

52f48d0d9a usbnet: fix status interrupt urb handling
Since commit 7b0c5f21f3
"sierra_net: keep status interrupt URB active", sierra_net triggers
status interrupt polling before the net_device is opened (in order to
properly receive the sync message response).

To be able to receive further interrupts, the interrupt urb needs to be
re-submitted, so this patch removes the bogus check for netif_running().

ec9f1d15db bonding: don't permit to use ARP monitoring in 802.3ad mode
Currently the ARP monitoring is not supported with 802.3ad, and it's
prohibited to use it via the module params.

However we still can set it afterwards via sysfs, cause we only check for
*LB modes there.

To fix this - add a check for 802.3ad mode in bonding_store_arp_interval.

41c1358e91 CIFS: SMB2/SMB3 Copy offload support (refcopy) phase 1
This first patch adds the ability for us to do a server side copy
(ie fast copy offloaded to the server to perform, aka refcopy)

"cp --reflink"

of one file to another located on the same server.  This
is much faster than traditional copy (which requires
reading and writing over the network and extra
memcpys).

This first version is not going to be copy
files larger than about 1MB (to Samba) until I add
support for multiple chunks and for autoconfiguring
the chunksize.

It includes:
1) processing of the ioctl
2) marshalling and sending the SMB2/SMB3 fsctl over the network
3) simple parsing of the response

It does not include yet (these will be in followon patches to come soon):
1) support for multiple chunks
2) support for autoconfiguring and remembering the chunksize
3) Support for the older style copychunk which Samba 4.1 server supports
(because this requires write permission on the target file, which
cp does not give you, apparently per-posix).  This may require
a distinct tool (other than cp) and other ioctl to implement.
