Pull ACPI and power management fixes from Rafael Wysocki:
"These are regression fixes (ACPI hotplug, cpufreq, hibernation, ACPI
LPSS driver), fixes for stuff that never worked correctly (ACPI GPIO
support in some cases and a wrong sign of an error code in the ACPI
core in one place), and one blacklist item for ACPI backlight
handling.
Specifics:
- Revert of a recent hibernation core commit that introduced a NULL
pointer dereference during resume for at least one user (Rafael J
Wysocki).
- Fix for the ACPI LPSS (Low-Power Subsystem) driver to disable
asynchronous PM callback execution for LPSS devices during system
suspend/resume (introduced in 3.16) which turns out to break
ordering expectations on some systems. From Fu Zhonghui.
- cpufreq core fix related to the handling of sysfs nodes during
system suspend/resume that has been broken for intel_pstate since
3.15 from Lan Tianyu.
- Restore the generation of "online" uevents for ACPI container
devices that was removed in 3.14, but some user space utilities
turn out to need them (Rafael J Wysocki).
- The cpufreq core fails to release a lock in an error code path
after changes made in 3.14. Fix from Prarit Bhargava.
- ACPICA and ACPI/GPIO fixes to make the handling of ACPI GPIO
operation regions (which means AML using GPIOs) work correctly in
all cases from Bob Moore and Srinivas Pandruvada.
- Fix for a wrong sign of the ACPI core's create_modalias() return
value in case of an error from Mika Westerberg.
- ACPI backlight blacklist entry for ThinkPad X201s from Aaron Lu"

Commit 46394fd01 (ACPI / hotplug: Move container-specific code out of
the core) removed the generation of "online" uevents for containers,
because "add" uevents are now generated for them automatically when
container system devices are registered. However, there are user
space tools that need to be notified when the container and all of
its children have been enumerated, which doesn't happen any more.
For this reason, add a mechanism allowing "online" uevents to be
generated for ACPI containers after enumerating the container along
with all of its children.

Pull i2c fixes from Wolfram Sang:
"This is probably not the kind of pull request you want to see that
late in the cycle. Yet, the ACPI refactorization was problematic
again and caused another two issues which need fixing. My holidays
with limited internet (plus travelling) and the developer's illness
didn't help either :(
The details:
- ACPI code was refactored out into a seperate file and as a
side-effect, the i2c-core module got renamed. Jean Delvare
rightfully complained about the rename being problematic for
distributions. So, Mika and I thought the least problematic way to
deal with it is to move all the code back into the main i2c core
source file. This is mainly a huge code move with some #ifdeffery
applied. No functional code changes. Our personal tests and the
testbots did not find problems. (I was thinking about reverting,
too, yet that would also have ~800 lines changed)
- The new ACPI code also had a NULL pointer exception, thanks to
Peter for finding and fixing it.
- Mikko fixed a locking problem by decoupling clock_prepare and
clock_enable.
- Addy learnt that the datasheet was wrong and reimplemented the
frequency setup according to the new algorithm.
- Fan fixed an off-by-one error when copying data
- Janusz fixed a copy'n'paste bug which gave a wrong error message
- Sergei made sure that "don't touch" bits are not accessed"

Commit 5d98e61d337c ("I2C/ACPI: Add i2c ACPI operation region support")
renamed the i2c-core module. This may cause regressions for
distributions, so put the ACPI code back into the core.

Pull one last block fix from Jens Axboe:
"We've had an issue with scsi-mq where probing takes forever. This was
bisected down to the percpu changes for blk_mq_queue_enter(), and the
fact we now suffer an RCU grace period when killing a queue. SCSI
creates and destroys tons of queues, so this let to 10s of seconds of
stalls at boot for some.
Tejun has a real fix for this, but it's too involved for 3.17. So
this is a temporary workaround to expedite the queue killing until we
can fold in the real fix for 3.18 when that merge window opens"

blk-mq, percpu_ref: implement a kludge for SCSI blk-mq stall during probe

blk-mq uses percpu_ref for its usage counter which tracks the number
of in-flight commands and used to synchronously drain the queue on
freeze. percpu_ref shutdown takes measureable wallclock time as it
involves a sched RCU grace period. This means that draining a blk-mq
takes measureable wallclock time. One would think that this shouldn't
matter as queue shutdown should be a rare event which takes place
asynchronously w.r.t. userland.
Unfortunately, SCSI probing involves synchronously setting up and then
tearing down a lot of request_queues back-to-back for non-existent
LUNs. This means that SCSI probing may take more than ten seconds
when scsi-mq is used.
This will be properly fixed by implementing a mechanism to keep
q->mq_usage_counter in atomic mode till genhd registration; however,
that involves rather big updates to percpu_ref which is difficult to
apply late in the devel cycle (v3.17-rc6 at the moment). As a
stop-gap measure till the proper fix can be implemented in the next
cycle, this patch introduces __percpu_ref_kill_expedited() and makes
blk_mq_freeze_queue() use it. This is heavy-handed but should work
for testing the experimental SCSI blk-mq implementation.

Pull crypto fixes from Herbert Xu:
"This fixes three issues:
- if ccp is loaded on a machine without ccp, it will incorrectly
activate causing all requests to fail. Fixed by preventing ccp
from loading if hardware isn't available.
- not all IRQs were enabled for the qat driver, leading to potential
stalls when it is used
- disabled buggy AVX CTR implementation in aesni"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: aesni - disable "by8" AVX CTR optimization
crypto: ccp - Check for CCP before registering crypto algs
crypto: qat - Enable all 32 IRQs

If the ccp is built as a built-in module, then ccp-crypto (whether
built as a module or a built-in module) will be able to load and
it will register its crypto algorithms. If the system does not have
a CCP this will result in -ENODEV being returned whenever a command
is attempted to be queued by the registered crypto algorithms.
Add an API, ccp_present(), that checks for the presence of a CCP
on the system. The ccp-crypto module can use this to determine if it
should register it's crypto alogorithms.

The recent conversion of saa7134 to vb2 unconvered a poll() bug that
broke the teletext applications alevt and mtt. These applications
expect that calling poll() without having called VIDIOC_STREAMON will
cause poll() to return POLLERR. That did not happen in vb2.
This patch fixes that behavior. It also fixes what should happen when
poll() is called when STREAMON is called but no buffers have been
queued. In that case poll() will also return POLLERR, but only for
capture queues since output queues will always return POLLOUT
anyway in that situation.
This brings the vb2 behavior in line with the old videobuf behavior.

In debugging an application that receives -ENOMEM from ib_reg_mr(), I
found that ib_umem_get() can fail because the pinned_vm count has
wrapped causing it to always be larger than the lock limit even with
RLIMIT_MEMLOCK set to RLIM_INFINITY.
The wrapping of pinned_vm occurs because the process that calls
ib_reg_mr() will have its mm->pinned_vm count incremented. Later a
different process with a different mm_struct than the one that
allocated the ib_umem struct ends up releasing it which results in
decrementing the new processes mm->pinned_vm count past zero and
wrapping.
I'm not entirely sure what circumstances cause a different process to
release the ib_umem than the one that allocated it but the kernel
stack trace of the freeing process from my situation looks like the
following:
Call Trace:
[<ffffffff814d64b1>] dump_stack+0x19/0x1b
[<ffffffffa0b522a5>] ib_umem_release+0x1f5/0x200 [ib_core]

[<ffffffff814e3dd0>] int_signal+0x12/0x17
The following patch fixes the issue by storing the pid struct of the
process that calls ib_umem_get() so that ib_umem_release and/or
ib_umem_account() can properly decrement the pinned_vm count of the
correct mm_struct.

The gist of the issue is that we firstly have drivers that span both
SCSI and networking. And at the top of that chain of dependencies
we have things like SCSI_FC_ATTRS and SCSI_NETLINK which are
selected.
But since select is a sledgehammer and ignores dependencies,
everything to select's SCSI_FC_ATTRS and/or SCSI_NETLINK has to also
explicitly select their dependencies and so on and so forth.
Generally speaking 'select' is supposed to only be used for child
nodes, those which have no dependencies of their own. And this
whole chain of dependencies in the scsi layer violates that rather
strongly.
So just make SCSI_NETLINK depend upon it's dependencies, and so on
and so forth for the things selecting it (either directly or
indirectly).

Steffen Klassert says:
====================
pull request (net): ipsec 2014-09-22
We generate a blackhole or queueing route if a packet
matches an IPsec policy but a state can't be resolved.
Here we assume that dst_output() is called to kill
these packets. Unfortunately this assumption is not
true in all cases, so it is possible that these packets
leave the system without the necessary transformations.
This pull request contains two patches to fix this issue:
1) Fix for blackhole routed packets.
2) Fix for queue routed packets.
Both patches are serious stable candidates.
Please pull or let me know if there are problems.

Currently we genarate a queueing route if we have matching policies
but can not resolve the states and the sysctl xfrm_larval_drop is
disabled. Here we assume that dst_output() is called to kill the
queued packets. Unfortunately this assumption is not true in all
cases, so it is possible that these packets leave the system unwanted.
We fix this by generating queueing routes only from the
route lookup functions, here we can guarantee a call to
dst_output() afterwards.

We cannot make struct qdisc_skb_cb bigger without impacting IPoIB,
or increasing skb->cb[] size.
Commit e0f31d849867 ("flow_keys: Record IP layer protocol in
skb_flow_dissect()") broke IPoIB.
Only current offender is sch_choke, and this one do not need an
absolutely precise flow key.
If we store 17 bytes of flow key, its more than enough. (Its the actual
size of flow_keys if it was a packed structure, but we might add new
fields at the end of it later)

If we try to rmmod the driver for an interface while sockets with
setsockopt(JOIN_ANYCAST) are alive, some refcounts aren't cleaned up
and we get stuck on:
unregister_netdevice: waiting for ens3 to become free. Usage count = 1
If we LEAVE_ANYCAST/close everything before rmmod'ing, there is no
problem.
We need to perform a cleanup similar to the one for multicast in
addrconf_ifdown(how == 1).

Changing the vlan stripping policy of the QP isn't supported by older
firmware versions for the INIT2RTR command. Nevertheless, we've used it.
Fix that by doing this policy change using INIT2RTR only if the firmware
supports it, otherwise, we call UPDATE_QP command to do the task.

Pull workqueue fix from Tejun Heo:
"create_singlethread_workqueue() is the old interface which is kept
around for backward compatibility - each should be reviewed to
determine whether singlethread usage was to save worker threads or for
ordering guarantee and whether it's depended upon by memory reclaim
path.
While adding NUMA support for unbound workqueues during v3.10, I
forgot to update it breaking the singlethread and ordering properties
on NUMA setups. The breakage was unfortunately rather subtle and went
without being reported until now.
The only missing piece is __WQ_ORDERED flag which makes the unbounded
workqueue use a single backend queue across different NUMA nodes.
It's fixed by making create_singlethread_workqueue() wrap
alloc_ordered_workqueue() so that possible future updates are
inherited automatically"

create_singlethread_workqueue() is a compat interface for single
threaded workqueue which maps to ordered workqueue w/ rescuer in the
current implementation. create_singlethread_workqueue() currently
implemented by invoking alloc_workqueue() w/ appropriate parameters.
8719dceae2f9 ("workqueue: reject adjusting max_active or applying
attrs to ordered workqueues") introduced __WQ_ORDERED to protect
ordered workqueues against dynamic attribute changes which can break
ordering guarantees but forgot to apply it to
create_singlethread_workqueue(). This in itself is okay as nobody
currently uses dynamic attribute change on workqueues created with
create_singlethread_workqueue().
However, 4c16bd327c ("workqueue: implement NUMA affinity for unbound
workqueues") broke singlethreaded guarantee for ordered workqueues
through allocating a separate pool_workqueue on each NUMA node by
default. A later change 8a2b75384444 ("workqueue: fix ordered
workqueues in NUMA setups") fixed it by allocating only one global
pool_workqueue if __WQ_ORDERED is set.
Combined, the __WQ_ORDERED omission in create_singlethread_workqueue()
became critical breaking its single threadedness and ordering
guarantee.
Let's make create_singlethread_workqueue() wrap
alloc_ordered_workqueue() instead so that it inherits __WQ_ORDERED and
can implicitly track future ordered_workqueue changes.
v2: I missed that __WQ_ORDERED now protects against pwq splitting
across NUMA nodes and incorrectly described the patch as a
nice-to-have fix to protect against future dynamic attribute
usages. Oleg pointed out that this is actually a critical
breakage due to 8a2b75384444 ("workqueue: fix ordered workqueues
in NUMA setups").

switcheroo problem related to hotplug").
A previous commit 5493b31f0b55 ("PCI: Add pci_ignore_hotplug() to ignore
hotplug events for a device") added equivalent functionality implemented in
a different way for both acpiphp and pciehp.

Powering off a hot-pluggable device, e.g., with pci_set_power_state(D3cold),
normally generates a hot-remove event that unbinds the driver.
Some drivers expect to remain bound to a device even while they power it
off and back on again. This can be dangerous, because if the device is
removed or replaced while it is powered off, the driver doesn't know that
anything changed. But some drivers accept that risk.
Add pci_ignore_hotplug() for use by drivers that know their device cannot
be removed. Using pci_ignore_hotplug() tells the PCI core that hot-plug
events for the device should be ignored.
The radeon and nouveau drivers use this to switch between a low-power,
integrated GPU and a higher-power, higher-performance discrete GPU. They
power off the unused GPU, but they want to remain bound to it.
This is a reimplementation of f244d8b623da ("ACPIPHP / radeon / nouveau:
Fix VGA switcheroo problem related to hotplug") but extends it to work with
both acpiphp and pciehp.
This fixes a problem where systems with dual GPUs using the radeon drivers
become unusable, freezing every few seconds (see bugzillas below). The
resume of the radeon device may also fail, e.g.,
This fixes problems on dual GPU systems where the radeon driver becomes
unusable because of problems while suspending the device, as in bug 79701:

This is a backport of commit b9347aff91ce4789619168539f08202d8d6a1177.
This backport is needed as without it the code will crash on 32-bit
systems.
The maximum values for additional input string or generated blocks is
larger than 1<<32. To ensure a sensible value on 32 bit systems, return
SIZE_MAX on 32 bit systems. This value is lower than the maximum
allowed values defined in SP800-90A. The standard allow lower maximum
values, but not larger values.
SIZE_MAX - 1 is used for drbg_max_addtl to allow
drbg_healthcheck_sanity to check the enforcement of the variable
without wrapping.

The performance regression that Josef Bacik reported in the pathname
lookup (see commit 99d263d4c5b2 "vfs: fix bad hashing of dentries") made
me look at performance stability of the dcache code, just to verify that
the problem was actually fixed. That turned up a few other problems in
this area.
There are a few cases where we exit RCU lookup mode and go to the slow
serializing case when we shouldn't, Al has fixed those and they'll come
in with the next VFS pull.
But my performance verification also shows that link_path_walk() turns
out to have a very unfortunate 32-bit store of the length and hash of
the name we look up, followed by a 64-bit read of the combined hash_len
field. That screws up the processor store to load forwarding, causing
an unnecessary hickup in this critical routine.
It's caused by the ugly calling convention for the "hash_name()"
function, and easily fixed by just making hash_name() fill in the whole
'struct qstr' rather than passing it a pointer to just the hash value.
With that, the profile for this function looks much smoother.

"A oneliner bugfix for the jinxed futex code:
- Drop hash bucket lock in the error exit path. I really could slap
myself for intruducing that bug while fixing all the other horror

and the timer department is not too proud about the following fixes:
- Deal with a long standing rounding bug in the timeval to jiffies
conversion. It's a real issue and this fix fell through the cracks
for quite some time.
- Another round of alarmtimer fixes. Finally this code gets used
more widely and the subtle issues hidden for quite some time are
noticed and fixed. Nothing really exciting, just the itty bitty
details which bite the serious users here and there"

timeval_to_jiffies tried to round a timeval up to an integral number
of jiffies, but the logic for doing so was incorrect: intervals
corresponding to exactly N jiffies would become N+1. This manifested
itself particularly repeatedly stopping/starting an itimer:
setitimer(ITIMER_PROF, &val, NULL);
setitimer(ITIMER_PROF, NULL, &val);
would add a full tick to val, _even if it was exactly representable in
terms of jiffies_ (say, the result of a previous rounding.) Doing
this repeatedly would cause unbounded growth in val. So fix the math.
Here's what was wrong with the conversion: we essentially computed
(eliding seconds)
jiffies = usec * (NSEC_PER_USEC/TICK_NSEC)
by using scaling arithmetic, which took the best approximation of
NSEC_PER_USEC/TICK_NSEC with denominator of 2^USEC_JIFFIE_SC =
x/(2^USEC_JIFFIE_SC), and computed:
jiffies = (usec * x) >> USEC_JIFFIE_SC
and rounded this calculation up in the intermediate form (since we
can't necessarily exactly represent TICK_NSEC in usec.) But the
scaling arithmetic is a (very slight) *over*approximation of the true
value; that is, instead of dividing by (1 usec/ 1 jiffie), we
effectively divided by (1 usec/1 jiffie)-epsilon (rounding
down). This would normally be fine, but we want to round timeouts up,
and we did so by adding 2^USEC_JIFFIE_SC - 1 before the shift; this
would be fine if our division was exact, but dividing this by the
slightly smaller factor was equivalent to adding just _over_ 1 to the
final result (instead of just _under_ 1, as desired.)
In particular, with HZ=1000, we consistently computed that 10000 usec
was 11 jiffies; the same was true for any exact multiple of
TICK_NSEC.
We could possibly still round in the intermediate form, adding
something less than 2^USEC_JIFFIE_SC - 1, but easier still is to
convert usec->nsec, round in nanoseconds, and then convert using
time*spec*_to_jiffies. This adds one constant multiplication, and is
not observably slower in microbenchmarks on recent x86 hardware.
Tested: the following program:
int main() {
struct itimerval zero = {{0, 0}, {0, 0}};
/* Initially set to 10 ms. */
struct itimerval initial = zero;
initial.it_interval.tv_usec = 10000;
setitimer(ITIMER_PROF, &initial, NULL);
/* Save and restore several times. */
for (size_t i = 0; i < 10; ++i) {
struct itimerval prev;
setitimer(ITIMER_PROF, &zero, &prev);
/* on old kernels, this goes up by TICK_USEC every iteration */
printf("previous value: %ld %ld %ld %ld\n",
prev.it_interval.tv_sec, prev.it_interval.tv_usec,
prev.it_value.tv_sec, prev.it_value.tv_usec);
setitimer(ITIMER_PROF, &prev, NULL);
}
return 0;

The hash_64() function historically does the multiply by the
GOLDEN_RATIO_PRIME_64 number with explicit shifts and adds, because
unlike the 32-bit case, gcc seems unable to turn the constant multiply
into the more appropriate shift and adds when required.
However, that means that we generate those shifts and adds even when the
architecture has a fast multiplier, and could just do it better in
hardware.
Use the now-cleaned-up CONFIG_ARCH_HAS_FAST_MULTIPLIER (together with
"is it a 64-bit architecture") to decide whether to use an integer
multiply or the explicit sequence of shift/add instructions.

It is useful for userspace to know that there not dealing with a regular
mouse but rather with a pointing stick (e.g. a trackpoint) so that
userspace can e.g. automatically enable middle button scrollwheel
emulation.
It is impossible to tell the difference from the evdev info without
resorting to putting a list of device / driver names in userspace, this is
undesirable.
Add a property which allows userspace to see if a device is a pointing
stick, and set it on all the pointing stick drivers.
