In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE
message, then a route is searched as if a packet was received on the
specified 'iif' interface.
However in IPv6, RTA_IIF is not interpreted in the same way:
'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the
RTA_IIF attribute.
As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look
for a route as if a packet was received on a specific interface.
Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a
route as if a packet was received on the specified interface", similar
to IPv4's 'inet_rtm_getroute()' interpretation.

If both addresses equal, nothing needs to be done. If the device is down,
then we simply copy the new address to dev->dev_addr. If the device is up,
then we add another loopback device with the new address, and if that does
not fail, we remove the loopback device with the old address. And only
then, we update the dev->dev_addr.

An infinite loop occurred if garp_attr_create was called with the values
of an existing attribute. This might happen if a previous leave request
for the attribute has not yet been followed by a PDU transmission (or,
if the application previously issued a join request for the attribute
and is now issuing another one, without having issued a leave request).
If garp_attr_create finds an existing attribute having the same values,
return the address to it. Its state will then get updated (i.e., if it
was in a leaving state, it will move into a non-leaving state and not
get deleted during the next PDU transmission).
To accomplish this fix, collapse garp_attr_insert into garp_attr_create
(which is its only caller).

We can deadlock if we have a write oplock and two processes
use the same file handle. In this case the first process can't
unlock its lock if the second process blocked on the lock in the
same time.
Fix it by using posix_lock_file rather than posix_lock_file_wait
under cinode->lock_mutex. If we request a blocking lock and
posix_lock_file indicates that there is another lock that prevents
us, wait untill that lock is released and restart our call.

drivers/hwmon/adm1031.c:292: warning: 'reg' may be used uninitialized in this function
While this is a false positive, it can easily be fixed by overloading the return
value from get_fan_auto_nearest with both register value and error return code
(the register value is never negative). Coincidentially, that also reduces
module size by a few bytes.

The code currently passes the register offset in the current block to
regcache_lookup_reg. This works fine as long as there is only one block and with
base register of 0, but in all other cases it will look-up the default for a
wrong register, which can cause unnecessary register writes. This patch fixes
it by passing the actual register number to regcache_lookup_reg.

Ben Widawsky reported missed IRQ issues and this patch here helps.
We have one other missed IRQ report still left on snb, reported by QA:
https://bugs.freedesktop.org/show_bug.cgi?id=46145
This is _not_ a regression due to the forcewake voodoo though, it
started showing up before that was applied and has been on-and-off for
the past few weeks. According to QA this patch does not help. But the
missed IRQ is always from the blt ring (despite running piglit, so
also render activity expected), so I'm hopefully that this is an issue
with the blt ring itself.

This is yet another chapter in the ongoing saga of bringing RC6 to Sandy
Bridge machines by default.
Now that we have discovered that RC6 issues are triggered by RC6+ state,
let's try to disable it by default. Plain RC6 is the one responsible for
most energy savings, and so far it haven't given any problems - at least,
none we are aware of.
So with this, when i915_enable_rc6=-1 (e.g., the default value), we'll
attempt to enable plain RC6 only on SNB. For Ivy Bridge, the behavior
stays the same as always - we enable both RC6 and deep RC6.
Note that while this exact patch does not has explicit tested-by's, the
equivalent settings were fixed in 3.3 kernel by a smaller patch. And it
has also received considerable testing through Canonical RC6 task-force
testing at https://wiki.ubuntu.com/Kernel/PowerManagementRC6. Up to date,
it looks like all the known issues are gone.
v2: improve description and reference a couple of open bugs related to
RC6 which seem to be fixed with this change.

This allows to select which rc6 modes are to be used via kernel parameter,
via a bitmask parameter. E.g.:
- to enable rc6, i915_enable_rc6=1
- to enable rc6 and deep rc6, i915_enable_rc6=3
- to enable rc6 and deepest rc6, use i915_enable_rc6=5
- to enable rc6, deep and deepest rc6, use i915_enable_rc6=7
Please keep in mind that the deepest RC6 state really should NOT be used
by default, as it could potentially worsen the issues with deep RC6. So do
enable it only when you know what you are doing. However, having it around
could help solving possible future rc6-related issues and their debugging
on user machines.
Note that this changes behavior - previously, value of 1 would enable both
RC6 and deep RC6. Now it should only enable RC6 and deep/deepest RC6
stages must be enabled manually.
v2: address Chris Wilson comments and clean up the code.

The BLT commands on gen2/3 utilize the fence registers and so we cannot
modify any fences for the object whilst those commands are in flight.
Currently we marked tiled commands as occupying a fence, but forgot to
restrict the untiled commands from preventing a fence being assigned
before they were completed.
One side-effect is that we ten have to double check that a fence was
allocated for a fenced buffer during move-to-active.

The ppgtt page directory lives in a snatched part of the gtt pte
range. Which naturally gets cleared on hibernate when we pull the
power. Suspend to ram (which is what I've tested) works because
despite the fact that this is a mmio region, it is actually back by
system ram.
Fix this by moving the page directory setup code to the ppgtt init
code (which gets called on resume).
This fixes hibernate on my ivb and snb.

Pull virtio S3 support patches from Amit Shah:
"Turns out S3 is not different from S4 for virtio devices: the device
is assumed to be reset, so the host and guest state are to be assumed
to be out of sync upon resume. We handle the S4 case with exactly the
same scenario, so just point the suspend/resume routines to the
freeze/restore ones.
Once that is done, we also use the PM API's macro to initialise the
sleep functions.
A couple of cleanups are included: there's no need for special thaw
processing in the balloon driver, so that's addressed in patches 1 and
2.
Testing: both S3 and S4 support have been tested using these patches
using a similar method used earlier during S4 patch development: a
guest is started with virtio-blk as the only disk, a virtio network
card, a virtio-serial port and a virtio balloon device. Ping from
guest to host, dd /dev/zero to a file on the disk, and IO from the
host on the virtio-serial port, all at once, while exercising S4 and
S3 (separately) were tested. They all continue to work fine after
resume. virtio balloon values too were tested by inflating and
deflating the balloon."

those lists of fields contain a specific format:
aldebaran:~> cat /sys/bus/event_source/devices/cpu/format/offcore_rsp
config1:0-63
So, those who wish to specify raw events can now use the following
event format:
-e cpu/cmask=1,event=2,umask=3
Most people will not want to specify any events (let alone raw
events), they'll just use whatever default event the tools use.
But for more obscure PMU events that have no cross-architecture
generic events the above syntax is more usable and a bit more
structured than specifying hex numbers."

Pull SCSI updates from James Bottomley:
"This is primarily another round of driver updates (lpfc, bfa, fcoe,
ipr) plus a new ufshcd driver. There shouldn't be anything
controversial in here (The final deletion of scsi proc_ops which
caused some build breakage has been held over until the next merge
window to give us more time to stabilise it).
I'm afraid, with me moving continents at exactly the wrong time,
anything submitted after the merge window opened has been held over to
the next merge window."

Split __lookup_hash into two component functions:
lookup_dcache - tries cached lookup, returns whether real lookup is needed
lookup_real - calls i_op->lookup
This eliminates code duplication between d_alloc_and_lookup() and
d_inode_lookup().

now we have __lookup_hash() open-coded if !dentry case;
just call the damn thing instead...
