Down was requesting queue disables, but then exited immediately
without waiting for the queues to actually disable. This could
allow any function called after i40evf_down to run immediately,
including i40evf_up, and causes a memory leak.
Removing the whole reinit_locked function is the best way
to go about this, and allows for the driver to handle the
state changes by requesting reset from the periodic timer.
Also, add a couple WARN_ONs in slow path to help us recognize
if we re-introduce this issue or missed any cases.

In i219, there is a hardware bug that prevented ULP entry.
A side effect of the original software fix for this was that EEE in
Sx couldn't be enabled.
This patch implements a modified flow that allows both ULP and EEE in Sx.

On power up, the MAC - PHY interface needs to be set to PCIe, even if

e1000e_disable_aspm called pci_disable_link_state_locked which requires
pci_bus_sem to be held, but is also called from places where this semaphore
was not previously acquired. This patch implements two flavors of

Dynamic page table allocation might wake the shrinker
when memory is requested for page table structures.
As this happens when we try to allocate the virtual address
during binding, our vma might be among the targets for eviction.
We should do i915_vma_pin() and do pin early in there like Chris
suggests but this is interim solution.
Shield our vma from shrinker by incrementing pin count before
the virtual address is allocated.
The proper place to fix this would be in gem, inside of
i915_vma_pin(). But we don't have that yet so take the short
cut as a intermediate solution.

We cannot let IPS enabled with no plane on the pipe:
BSpec: "IPS cannot be enabled until after at least one plane has
been enabled for at least one vertical blank." and "IPS must be
disabled while there is still at least one plane enabled on the
same pipe as IPS." This restriction apply to HSW and BDW.
However a shortcut path on update primary plane function
to make primary plane invisible by setting DSPCTRL to 0
was leting IPS enabled while there was no
other plane enabled on the pipe causing flickerings that we were
believing that it was caused by that other restriction where
ips cannot be used when pixel rate is greater than 95% of cdclok.

While the commit [d0a601c278de: ALSA: jack: Fix the id uniqueness
check] fixes the wrong string check, it leads to a worse result -- the
loop in get_available_index() goes into an endless loop. The cause is
that snd_ctl_find_id() returns the object assigned to the numid if
it's set. Thus it points to the previous entry again.
This patch clears the numid field for the next call properly.

set in periodic mode
On some archs, the local clockevent device stops in deep cpuidle states.
The broadcast framework is used to wakeup cpus in these idle states, in
which either an external clockevent device is used to send wakeup ipis
or the hrtimer broadcast framework kicks in in the absence of such a
device. One cpu is nominated as the broadcast cpu and this cpu sends
wakeup ipis to sleeping cpus at the appropriate time. This is the
implementation in the oneshot mode of broadcast.
In periodic mode of broadcast however, the presence of such cpuidle
states results in the cpuidle driver calling tick_broadcast_enable()
which shuts down the local clockevent devices of all the cpus and
appoints the tick broadcast device as the clockevent device for each of
them. This works on those archs where the tick broadcast device is a
real clockevent device. But on archs which depend on the hrtimer mode
of broadcast, the tick broadcast device hapens to be a pseudo device.
The consequence is that the local clockevent devices of all cpus are
shutdown and the kernel hangs at boot time in periodic mode.
Let us thus not register the cpuidle states which have
CPUIDLE_FLAG_TIMER_STOP flag set, on archs which depend on the hrtimer
mode of broadcast in periodic mode. This patch takes care of doing this
on powerpc. The cpus would not have entered into such deep cpuidle
states in periodic mode on powerpc anyway. So there is no loss here.

On the MacBook Pro, power of the gpu is cut by a gmux chip. Sometimes
the gpu gets stuck in powersaving mode and refuses to wake up
("Refused to change power state, currently in D3"). Inserting a
delay between setting the gpu to D3hot and cutting the power seems
to help (most of the time). This issue and its (partial) remediation
by the patch was observed with an Nvidia GT650M (NVE7 / GK107).

Pull sound updates from Takashi Iwai:
"It was a busy development cycle at this time, as you can see a wide
range of changes in diffstat. There are no big changes but many
refactoring and improvements. Here we go some highlights:
ALSA core:
- Procfs codes were cleaned up to use seq_file
- Procfs can be opt out via Kconfig (only for EXPERT)
- Two types of jack API were unified finally; now both kctl and input
jack devs are handled via a single function call.
HD-audio:
- Continued code restructuring for the future ASoC driver; now HDA
controller driver is split to a core helper module.
- Preliminary codes for Skylake audio support in HDA core.
- Proper i915 gfx power well management for SKL & co
- Enabled runtime PM as default for Intel HDMI/DP codecs
- Newer Tegra chip supports
- More quirks for Dell headsets, Alienware (with CA0132), etc.
- A couple of DRM ELD helper API functions
ASoC:
- Support for loading ASoC topology maps from firmware, intended to
be used to allow self-describing DSP firmware images to be built
which can map controls added by the DSP to userspace without the
kernel needing to know about individual DSP firmwares
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring
- Big refactoring, cleanup and enhancement for the Wolfson ADSP
driver
- Cleanup series for TI TAS2552 and R-CAR drivers
- Fixes and improvements on RT56xx codecs
- Support for TI TAS571x power amplifiers
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs
- Support for x86 systems with RT5650 and Qualcomm Storm
- Support for Mediatek AFE (Audio Front End) unit
- Other various small fixes to ASoC codec drivers
Firewire:
- Enhanced to allow non-blocking streams to use timestamp
synchronization
- Improve support for DM1500 and BeBoBv3
Misc:
- Cleanup of old pci API functions over all PCI sound drivers
- Fix long-standing regression of the old powermac i2c setup"

which will let user-space tools (such as dmidecode) access the table
without relying on /dev/mem"

There is a helpful comment in do_exit() that states we sync the mm's RSS
info before statistics gathering.
The function that does the statistics gathering is called right above that
comment.
Change the code to obey the comment.

This allows detecting improper format string at build time, like:
fs/coredump.c:225:5: warning: format '%ld' expects argument of type 'long int', but argument 3 has type 'int' [-Wformat=]
err = cn_printf(cn, "%ld", cprm->siginfo->si_signo);
^
As si_signo is always an int, the format should be %d here.

When adding __printf attribute to cn_printf, gcc reports some issues:
fs/coredump.c:213:5: warning: format '%d' expects argument of type
'int', but argument 3 has type 'kuid_t' [-Wformat=]
err = cn_printf(cn, "%d", cred->uid);
^
fs/coredump.c:217:5: warning: format '%d' expects argument of type
'int', but argument 3 has type 'kgid_t' [-Wformat=]
err = cn_printf(cn, "%d", cred->gid);
^
These warnings come from the fact that the value of uid/gid needs to be
extracted from the kuid_t/kgid_t structure before being used as an
integer. More precisely, cred->uid and cred->gid need to be converted to
either user-namespace uid/gid or to init_user_ns uid/gid.
Use init_user_ns in order not to break existing ABI, and document this in
Documentation/sysctl/kernel.txt.
While at it, format uid and gid values with %u instead of %d because
uid_t/__kernel_uid32_t and gid_t/__kernel_gid32_t are unsigned int.

The "fh_len" passed to ->fh_to_* is not guaranteed to be that same as that
returned by encode_fh - it may be larger.
With NFSv2, the filehandle is fixed length, so it may appear longer than
expected and be zero-padded.
So we must test that fh_len is at least some value, not exactly equal to
it.
