Since wait_for_atomic doesn't re-check the wait-for condition after
expiry of the timeout it can fail when called from non-atomic context
even if the condition is set correctly before the expiry. Fix this by
using the non-atomic wait_for instead.

I noticed this via the PLL locking timing out incorrectly, with this fix
I couldn't reproduce the problem.

During hibernation the cached DP port register value will be left with
whatever value we have there when we create the hibernation image.
Currently that means the port (and eDP PLL) will be off in the cached
value. However when we resume there is no guarantee that the value
in the actual register will match the cached value. If i915 isn't
loaded in the kernel that loads the hibernation image, the port may
well be on (eg. left on by the BIOS). The encoder state readout
does the right thing in this case and updates our encoder state
to reflect the actual hardware state. However the post-resume modeset
will then use the stale cached port register value in
intel_dp_link_down() and potentially confuse the hardware.
This was caught by the following assert
WARNING: CPU: 3 PID: 5288 at ../drivers/gpu/drm/i915/intel_dp.c:2184 assert_edp_pll+0x99/0xa0 [i915]
eDP PLL state assertion failure (expected on, current off)
on account of the eDP PLL getting prematurely turned off when
shutting down the port, since the DP_PLL_ENABLE bit wasn't set
in the cached register value.
Presumably I introduced this problem in
commit 6fec76628333 ("drm/i915: Use intel_dp->DP in eDP PLL setup")
as before that we didn't update the cached value after shuttting the
port down. That's assuming the port got enabled at least once prior
to hibernating. If that didn't happen then the cached value would
still have been totally out of sync with reality (eg. first boot w/o
eDP on, then hibernate, and then resume with eDP on).
So, let's fix this properly and refresh the cached register value from
the hardware register during resume.
DDI platforms shouldn't use the cached value during port disable at
least, so shouldn't have this particular issue. They might still have
issues if we skip the initial modeset and then try to retrain the link
or something. But untangling this DP vs. DDI mess is a bigger topic,
so let's jut punt on DDI for now.

Marvell 88E1111 currently uses the generic marvell config ANEG function.
This function has a sequence accessing Page 5 and Register 31,
both of which are not defined or reserved for this PHY.
Hence this patch adds a new config ANEG function for Marvell 88E1111
without these erroneous accesses.

If we have a system which uses fixed PHY devices and calls
fixed_phy_register() then fixed_phy_unregister() we can exhaust the
number of fixed PHYs available after a while, since we keep incrementing
the variable phy_fixed_addr, but we never decrement it.
This patch fixes that by converting the fixed PHY allocation to using
IDA, which takes care of the allocation/dealloaction of the PHY
addresses for us.

The proc connector messages include a sequence number, allowing userspace
programs to detect lost messages. However, performing this detection is
currently more difficult than necessary, since netlink messages can be
delivered to the application out-of-order. To fix this, leave pre-emption
disabled during cn_netlink_send(), and use GFP_NOWAIT.
The following was written as a test case. Building the kernel w/ make -j32
proved a reliable way to generate out-of-order cn_proc messages.
int
main(int argc, char *argv[])

static uint32_t last_seq[CPU_SETSIZE], seq;

Since commit 7bb11dc9f59d ("bonding: unify all places where
actor-oper key needs to be updated."), the logic in bonding to handle
selection between multiple aggregators has not functioned.
This affects only configurations wherein the bonding slaves
connect to two discrete aggregators (e.g., two independent switches, each
with LACP enabled), thus creating two separate aggregation groups within a
single bond.
The cause is a change in 7bb11dc9f59d to no longer set
AD_PORT_BEGIN on a port after a link state change, which would cause the
port to be reselected for attachment to an aggregator as if were newly
added to the bond. We cannot restore the prior behavior, as it
contradicts IEEE 802.1AX 5.4.12, which requires ports that "become
inoperable" (lose carrier, setting port_enabled=false as per 802.1AX
5.4.7) to remain selected (i.e., assigned to the aggregator). As the port
now remains selected, the aggregator selection logic is not invoked.
A side effect of this change is that aggregators in bonding will
now contain ports that are link down. The aggregator selection logic
does not currently handle this situation correctly, causing incorrect
aggregator selection.
This patch makes two changes to repair the aggregator selection
logic in bonding to function as documented and within the confines of the
standard:
First, the aggregator selection and related logic now utilizes the
number of active ports per aggregator, not the number of selected ports
(as some selected ports may be down). The ad_select "bandwidth" and
"count" options only consider ports that are link up.
Second, on any carrier state change of any slave, the aggregator
selection logic is explicitly called to insure the correct aggregator is
active.

intel_pstate_set_policy() is invoked by the cpufreq core during
driver initialization, on changes of policy attributes (minimim and
maximum frequency, for example) via sysfs and via CPU notifications
from the platform firmware. On some platforms the latter may occur
relatively often.
Commit bb6ab52f2bef (intel_pstate: Do not set utilization update hook
too early) made intel_pstate_set_policy() clear the CPU's utilization
update hook before updating the policy attributes for it (and set the
hook again after doind that), but that involves invoking
synchronize_sched() and adds overhead to the CPU notifications
mentioned above and to the sched-RCU handling in general.
That extra overhead is arguably not necessary, because updating
policy attributes when the CPU's utilization update hook is active
should not lead to any adverse effects, so drop the clearing of
the hook from intel_pstate_set_policy() and make it check if
the hook has been set already when attempting to set it.

The USB core contains a bug that can show up when a USB-3 host
controller is removed. If the primary (USB-2) hcd structure is
released before the shared (USB-3) hcd, the core will try to do a
double-free of the common bandwidth_mutex.
The problem was described in graphical form by Chung-Geol Kim, who
first reported it:

|__________________|
=================================================
This happens because hcd_release() frees the bandwidth_mutex whenever
it sees a primary hcd being released (which is not a very good idea
in any case), but in the course of releasing the primary hcd, it
changes the pointers in the shared hcd in such a way that the shared
hcd will appear to be primary when it gets released.
This patch fixes the problem by changing hcd_release() so that it
deallocates the bandwidth_mutex only when the _last_ hcd structure
referencing it is released. The patch also removes an unnecessary
test, so that when an hcd is released, both the shared_hcd and
primary_hcd pointers in the hcd's peer will be cleared.

checks whether or not preemption is disable, and get_cpu_ptr() provides
a convenient wrapper for operating on the cpu ptr inside a preemption

By default, mdiobus_alloc() sets the PHYs to polling mode, but a
pointer size memcpy means that a couple IRQs end up being overwritten
with a value of 0. This means that PHY_POLL is disabled and results
in unpredictable behavior depending on the PHY's location on the
MDIO bus. Remove that memcpy and the now unused phy_irq member to
force the SMSC911x PHYs into polling mode 100% of the time.

An ENOMEM when creating a pair tty in tty_ldisc_setup causes a null
pointer dereference in devpts_kill_index because tty->link->driver_data
is NULL. The oops was triggered with the pty stressor in stress-ng when
in a low memory condition.
tty_init_dev tries to clean up a tty_ldisc_setup ENOMEM error by calling
release_tty, however, this ultimately tries to clean up the NULL pair'd
tty in pty_unix98_remove, triggering the Oops.
Add check to pty_unix98_remove to only clean up fsi if it is not NULL.

Currently the ad7266 driver treats any failure to get vref as though the
regulator were not present but this means that if probe deferral is
triggered the driver will act as though the regulator were not present.
Instead only use the internal reference if we explicitly got -ENODEV which
is what is returned for absent regulators.

The ad7266 driver attempts to support deciding between the use of internal
and external power supplies by checking to see if an error is returned when
requesting the regulator. This doesn't work with the current code since the
driver uses a normal regulator_get() which is for non-optional supplies
and so assumes that if a regulator is not provided by the platform then
this is a bug in the platform integration and so substitutes a dummy
regulator. Use regulator_get_optional() instead which indicates to the
framework that the regulator may be absent and provides a dummy regulator
instead.

This is caused by the vt visual_init() function calling into
fbcon_init() with a vc_cur_blink_ms value of zero. This is a
transient condition, as it is later set to a non-zero value. But, if
the timer happens to expire while the blink rate is zero, it goes into
an endless loop, and we get soft lockup.
The fix is to initialize vc_cur_blink_ms before calling the con_init()
function.

This is the third version of the patchset previously sent [1]. I have
basically only rebased it on top of 4.7-rc1 tree and dropped "dm: get
rid of superfluous gfp flags" which went through dm tree. I am sending
it now because it is tree wide and chances for conflicts are reduced
considerably when we want to target rc2. I plan to send the next step
and rename the flag and move to a better semantic later during this
release cycle so we will have a new semantic ready for 4.8 merge window
hopefully.
Motivation:
While working on something unrelated I've checked the current usage of
__GFP_REPEAT in the tree. It seems that a majority of the usage is and
always has been bogus because __GFP_REPEAT has always been about costly
high order allocations while we are using it for order-0 or very small
orders very often. It seems that a big pile of them is just a
copy&paste when a code has been adopted from one arch to another.
I think it makes some sense to get rid of them because they are just
making the semantic more unclear. Please note that GFP_REPEAT is
documented as
* __GFP_REPEAT: Try hard to allocate the memory, but the allocation attempt
* _might_ fail. This depends upon the particular VM implementation.
while !costly requests have basically nofail semantic. So one could
reasonably expect that order-0 request with __GFP_REPEAT will not loop
for ever. This is not implemented right now though.
I would like to move on with __GFP_REPEAT and define a better semantic
for it.
$ git grep __GFP_REPEAT origin/master | wc -l
111
$ git grep __GFP_REPEAT | wc -l
36
So we are down to the third after this patch series. The remaining
places really seem to be relying on __GFP_REPEAT due to large allocation
requests. This still needs some double checking which I will do later
after all the simple ones are sorted out.
I am touching a lot of arch specific code here and I hope I got it right
but as a matter of fact I even didn't compile test for some archs as I
do not have cross compiler for them. Patches should be quite trivial to
review for stupid compile mistakes though. The tricky parts are usually
hidden by macro definitions and thats where I would appreciate help from
arch maintainers.
[1] http://lkml.kernel.org/r/1461849846-27209-1-git-send-email-mhocko@kernel.org
This patch (of 19):
__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations. Yet we
have the full kernel tree with its usage for apparently order-0
allocations. This is really confusing because __GFP_REPEAT is
explicitly documented to allow allocation failures which is a weaker
semantic than the current order-0 has (basically nofail).
Let's simply drop __GFP_REPEAT from those places. This would allow to
identify place which really need allocator to retry harder and formulate
a more specific semantic for what the flag is supposed to do actually.
