Fix typos and add the following to the scripts/spelling.txt:
aligment||alignment
I did not touch the "N_BYTE_ALIGMENT" macro in
drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable
impact.
I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif. It is surely safe and I
confirmed "_alignment_handler" is correct.
I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

Fix typos and add the following to the scripts/spelling.txt:

I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the
list. I felt it is endless to find words that start with "user" such as
"userland" etc., so must draw a line somewhere.

The object palm_bk3710_port_info of type ide_port_info is never
referenced anywhere after initialization by palm_bk3710_probe. It is
also passed as a parameter to ide_host_add which is called from the init
function but this call doesn't store the object reference anywhere, and
it only dereferences the values of the fields. Therefore add __initdata
to its declaration.

It was reported that on some machines, there is overlap between ACPI
NVS area and BERT address range. This appears reasonable because BERT
contents need to be non-volatile across reboot. But this will cause
resources conflict in current Linux kernel implementation because the
ACPI NVS area is marked as busy. The resource conflict is fixed via
excluding the ACPI NVS area when requesting IO resources for BERT.
When accessing the BERT contents, the whole BERT address range will be
ioremapped and accessed.

Add a struct irq_affinity pointer to the find_vqs methods, which if set
is used to tell the PCI layer to create the MSI-X vectors for our I/O
virtqueues with the proper affinity from the start. Compared to after
the fact affinity hints this gives us an instantly working setup and
allows to allocate the irq descritors node-local and avoid interconnect
traffic. Last but not least this will allow blk-mq queues are created
based on the interrupt affinity for storage drivers.

This lets IRQ layer handle dispatching IRQs to separate handlers for the
case where we don't have per-VQ MSI-X vectors, and allows us to greatly
simplify the code based on the assumption that we always have interrupt
vector 0 (legacy INTx or config interrupt for MSI-X) available, and
any other interrupt is request/freed throught the VQ, even if the
actual interrupt line might be shared in some cases.
This allows removing a great deal of variables keeping track of the
interrupt state in struct virtio_pci_device, as we can now simply walk the
list of VQs and deal with per-VQ interrupt handlers there, and only treat
vector 0 special.
Additionally clean up the VQ allocation code to properly unwind on error
instead of having a single global cleanup label, which is error prone,
and in this case also leads to more code.

We don't really need struct virtio_pci_vq_info, as most field in there
are redundant:
- the vq backpointer is not strictly neede to start with
- the entry in the vqs list is not needed - the generic virtqueue already
has list, we only need to check if it has a callback to get the same
semantics
- we can use a simple array to look up the MSI-X vec if needed.
- That simple array now also duoble serves to replace the per_vq_vectors
flag

If last avail idx is not equal to cached avail idx, we're sure there's
still available buffers in the virtqueue so there's no need to re-read

Commit 653d2ffd6405 ("qed*: Fix link indication race") introduced another
race - one of the inner functions called from the link-change flow is
explicitly using the slowpath context dedicated PTT instead of gaining
that PTT from the caller. Since this flow can now be called from
a different context as well, we're in risk of the PTT breaking.

A PF syncronizes all IOV activity relating to its VFs
by using a single workqueue handling the work.
The workqueue would reach a bitmask of pending VF events
and act upon each in turn.
Problem is that the indication of a VF message [which sets
the 'vf event' bit for that VF] arrives and is set in
the slowpath attention context, which isn't syncronized with
the processing of the events.
When multiple VFs are present, it's possible that PF would
lose the indication of one of the VF's pending evens, leading
that VF to later timeout.
Instead of adding locks/barriers, simply move from a bitmask
into a per-VF indication inside that VF entry in the PF database.

After commit 9908859acaa9 (cpuidle/menu: add per CPU PM QoS resume
latency consideration) the cpuidle menu governor calls
dev_pm_qos_read_value() on CPU devices to read the current resume
latency QoS constraint values for them. That function takes a spinlock
to prevent the device's power.qos pointer from becoming NULL during
the access which is a problem for the RT patchset where spinlocks are
converted into mutexes and the idle loop stops working.
However, it is not even necessary for the menu governor to take
that spinlock, because the power.qos pointer accessed under it
cannot be modified during the access anyway.
For this reason, introduce a "raw" routine for accessing device
QoS resume latency constraints without locking and use it in the
menu governor.

This patch introduces two counters for ABORT_TASK success +
failure under:
/sys/kernel/config/target/core/$HBA/$DEV/statistics/scsi_tgt_dev/
that are useful for diagnosing various backend device latency
and front fabric issues.
Normally when folks see alot of aborts_complete happening,
it means the backend device I/O completion latency is high,
and not returning completions fast enough before host side
timeouts trigger.
And normally when folks see alot of aborts_no_task, it means
completions are being posted by target-core into fabric driver
code, but the responses aren't making it back to the host.

Due to the long standing checks in iscsit_snmp_get_tiqn()
that assume conn->sess->tpg dereference of tpg->tpg_tiqn
for iscsit_collect_login_stats() usage, some of the early
login failure cases like ISCSI_LOGIN_STATUS_TGT_FORBIDDEN
where not getting incremented, due to sess->tpg assignment
happening later in iscsi_login_zero_tsih_s2().
Instead, use the earlier conn->tpg assignment done by
iscsi_target_locate_portal() -> iscsit_get_tpg_from_np()
so the existing counters are incremented correctly for
the various early login failure cases.
Also, go ahead and drop the old rate limiting check in
iscsit_collect_login_stats(), so we get the true number
of failed login attempts in the existing statistics.

When transport_clear_lun_ref() is shutting down a se_lun via
configfs with new I/O in-flight, it's possible to trigger a
NULL pointer dereference in transport_lookup_cmd_lun() due
to the fact percpu_ref_get() doesn't do any __PERCPU_REF_DEAD
checking before incrementing lun->lun_ref.count after
lun->lun_ref has switched to atomic_t mode.
This results in a NULL pointer dereference as LUN shutdown
code in core_tpg_remove_lun() continues running after the
existing ->release() -> core_tpg_lun_ref_release() callback
completes, and clears the RCU protected se_lun->lun_se_dev
pointer.
During the OOPs, the state of lun->lun_ref in the process
which triggered the NULL pointer dereference looks like
the following on v4.1.y stable code:
struct se_lun {
lun_link_magic = 4294932337,
lun_status = TRANSPORT_LUN_STATUS_FREE,
.....
lun_se_dev = 0x0,
lun_sep = 0x0,
.....
lun_ref = {
count = {
counter = 1
},
percpu_count_ptr = 3,
release = 0xffffffffa02fa1e0 <core_tpg_lun_ref_release>,
confirm_switch = 0x0,
force_atomic = false,
rcu = {
next = 0xffff88154fa1a5d0,
func = 0xffffffff8137c4c0 <percpu_ref_switch_to_atomic_rcu>
}
}
}
To address this bug, use percpu_ref_tryget_live() to ensure
once __PERCPU_REF_DEAD is visable on all CPUs and ->lun_ref
has switched to atomic_t, all new I/Os will fail to obtain
a new lun->lun_ref reference.
Also use an explicit percpu_ref_kill_and_confirm() callback
to block on ->lun_ref_comp to allow the first stage and
associated RCU grace period to complete, and then block on
->lun_ref_shutdown waiting for the final percpu_ref_put()
to drop the last reference via transport_lun_remove_cmd()
before continuing with core_tpg_remove_lun() shutdown.

vmware tools has a daemon that gets layout information from the GUI and
forwards it to DRM so that the modesetting code can set preferred connector
locations and modes. This daemon was using control nodes but since control
nodes were just removed, make it possible for the daemon to use render- or
primary nodes instead. This is a bit ugly but will allow drm to proceed with
removal of the mostly unused control-node code and allow vmware to proceed
with fixing up automatic layout settings for gnome-shell/wayland.
We bump minor to inform user-space about the api change.

The cited commit makes a great job of finding optimal shift/multiplier
values assuming a 10 seconds wrap around, but forgot to change the
overflow_period computation.
It overflows in cyclecounter_cyc2ns(), and the final result is 804 ms,
which is silly.
Lets simply use 5 seconds, no need to recompute this, given how it is
supposed to work.
Later, we will use a timer instead of a work queue, since the new RX
allocation schem will no longer need mlx4_en_recover_from_oom() and the
service_task firing every 250 ms.

The original github source allowed for the cache-line-size property
to be missing. Since recent firmwares also require this property,
it makes sense to always require it in the driver as well.
If the cache-line-size property is missing, then the driver probe
should fail as no dev since the kernel and dt may be out of sync.
The fix is to add a check for the return value of of_property_read_u32.
Changes V2:
1. Add error message if cache-line-size is missing.
2. Simple check for non-zero return value from
of_property_read_u32.

Second set of IIO fixes for IIO in the 4.11 cycle.
This series consists of fixes that either came in after the merge window
had opened or are fixes for work that merged during the merge window so had
to wait for that to hit mainline.
* 104-quad-8
- Fix an off by one error in the register address for the flag register.
* rcar-gyroadc
- protect against possible issues in future by dealing with childmode not
being in a valid state. This also deals with some build warnings.
* xilinx
- fix some error handling paths to ensure resources are released in
reverse order of being acquired.

Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:
Scope (_SB)
{
(...)
Device (ATKD)
{
(...)
Method (WMNB, 3, Serialized)
{
(...)
If (LEqual (IIA0, 0x00010002))
{
OWGD (IIA1)
Return (One)
}
}
}
}
So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.
This commit skips registering RFKill switches at all for these laptops,
to allow the asus-wireless driver to drive the airplane mode LED
correctly through the ASHS ACPI device. Relying on the presence of ASHS
and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least
21 different laptops.

MODULE_DEVICE_TABLE is all that is needed for fujitsu-laptop to be
properly autoloaded based on presence of its associated ACPI devices, so
remove redundant MODULE_ALIAS entries.

Presence of ACPI method SBL2 should be checked on all models rather than
just the ones with predefined hotkey keycode overrides. Move most of
dmi_check_cb_common() to acpi_fujitsu_bl_add(). Adjust indentation to
make checkpatch happy.

A separate variable is not needed to handle error codes returned by
acpi_bus_register_driver(). If the latter fails, just use the value it
returned as the value returned by fujitsu_init().

Both acpi_fujitsu_bl_notify() and acpi_fujitsu_laptop_notify() are
defined before they are first used, so remove their forward declarations
as they are redundant.
