If the DASD device gets blocked for any reason, e.g. because it is reserved
somewhere, the host_access_count sysfs entry or the host_access_list
debugfs entry may sleep forever. Make it interruptible so that userspace
can use ^C to abort the operation.

A DASD device consists of the device itself and a discipline with a
corresponding private structure. These fields are set up during online
processing right after the device is created and before it is processed by
the state machine and made available for I/O.
During offline processing the discipline pointer and the private data gets
freed within the state machine and without protection of the existing
reference count. This might lead to a kernel panic because a function might
have taken a device reference and accesses the discipline pointer and/or
private data of the device while this is already freed.
Fix by freeing the discipline pointer and the private data after ensuring
that there is no reference to the device left.

Internal I/O is processed by the _sleep_on_function which might wait for a
device to get operational. During offline processing this will never happen
and therefore the refcount of the device will not drop to zero and the
offline processing blocks as well.
Fix by letting requests fail in the _sleep_on function during offline
processing. No further handling of the requests is necessary since this is
internal I/O and the device is thrown away afterwards.

When a new function is attached to an iommu domain we need to register
I/O address translation parameters. Since commit
69eea95c ("s390/pci_dma: fix DMA table corruption with > 4 TB main memory")
start_dma and end_dma correctly describe the range of usable I/O addresses.
Simplify the code by using these values directly.

The workqueue "appldata_wq" has been replaced with an ordered dedicated
workqueue.
WQ_MEM_RECLAIM has not been set since the workqueue is not being used on
a memory reclaim path.
The adapter->work_queue queues multiple work items viz
&adapter->scan_work, &port->rport_work, &adapter->ns_up_work,
&adapter->stat_work, adapter->work_queue, &adapter->events.work,
&port->gid_pn_work, &port->test_link_work. Hence, an ordered
dedicated workqueue has been used.
WQ_MEM_RECLAIM has been set to ensure forward progress under memory

Pull GPIO fixes from Linus Walleij:
"Here are a few GPIO fixes for v4.8.
I was expecting some fallout from the new chardev rework but nothing
like that turned up att all. Instead a Kconfig confusion that I think
I have finally nailed, then some ordinary driver noise and trivia.
This fixes a Kconfig issue with UM: when I made GPIOLIB available to
all archs, that included UM, but the OF part of GPIOLIB requires
HAS_IOMEM, so we add HAS_IOMEM as a dependency to OF_GPIO.
This in turn exposed the fact that a few GPIO drivers were implicitly
assuming OF_GPIO as their dependency but instead depended on OF alone
(the typical problem being a pointer inside gpio_chip not existing
unless OF_GPIO is selected) and then UM would fail to compile with
these drivers instead. Then I lost patience and made any GPIO driver
depending on just OF depend on OF_GPIO instead, that is certainly what
they meant and the only thing that makes sense anyway. GPIO with just
OF but !OF_GPIO does not make sense.
Also a fix for the max730x driver data pointer, and a minor comment
fix for the GPIO tools"

This is an entirely new driver instead of yet another set of patches
to sb_edac.c because:
1) Mapping from PCI devices to socket/memory controller is significantly
different. Skylake scatters devices on a socket across a number of
PCI buses.
2) There is an extra level of interleaving via the "mcroute" register
that would be a little messy to squeeze into the old driver.
3) Validation is getting too expensive. Changes to sb_edac need to
be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and
Knights Landing.

The drivers that depend on OF but not OF_GPIO are wreaking havoc
with the autobuilders for archs that have all requirements for
OF but not for OF_GPIO, particularly the UM (Usermode) arch does
not have iomem (NO_IOMEM) which result in configuring GPIOLIB but
without OF_GPIO which is wrong if the driver is using the .of_node
of the gpiochip, which only appears with OF_GPIO.
After a brief look at the drivers just depending on OF it seems
most if not all of them actually require stuff from gpiolib-of so
the dependency is wrong in the first place.
This simply patches the Kconfig so that all GPIO drivers using OF
depend on OF_GPIO rather than just OF.

The UserMode (UM) Linux build was failing in gpiolib-of as it requires
ioremap()/iounmap() to exist, which is absent from UM. The non-existence
of IO memory is negatively defined as CONFIG_NO_IOMEM which means we

This reverts commit:
fa7d81bb3c269 ("drm/fb-helper: Reduce READ_ONCE(master) to lockless_dereference")
As Peter explained:
[...] lockless_dereference() is _stronger_ than READ_ONCE(), not weaker.
[...]
Also, clue is in the name: 'dereference', you don't actually dereference
the pointer here, only load it.
My next patch breaks the compile without this revert, because it assumes
you want to deference and thus also need the struct type visible (which
it isn't here), so revert it.

As pointed out by Jamal, an action could be shared by
multiple filters, so we can't use list to chain them
any more after we get rid of the original tc_action.
Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.
The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.

Intel Wired LAN Driver Updates 2016-08-16
This series contains fixes to e1000e, igb, ixgbe and i40e.
Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation
math in several functions.
Jarod Wilson provides a fix for e1000e which had to broken up into 2
patches, first is prepares the driver for expanding the list of NICs
that have occasional ~10 hour clock jumps when being used for PTP.
Second patch actually fixes i218 silicon which has been experiencing
the clock jumps while using PTP.
Alex provides 2 patches for ixgbe now that he is back at Intel. First
fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches
which resulted in disabling VLAN filtering for all the VFs. Second
corrects the support for disabling the VLAN tag filtering via the
feature bit.
Lastly, David fixes i40e which was causing a kernel panic when
non-contiguous traffic classes or traffic classes not starting with TC0,
were configured on a link partner switch. To fix this, changed the
logic when determining the total number of TCs enabled.

When packets enter the device they are classified to a priority group
(PG) buffer based on their PCP value. After their egress port and
traffic class are determined they are moved to the switch's shared
buffer and await transmission, if:
(Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
||
(Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
Packets scheduled to transmission through CPU port (trapped to CPU) use
traffic class 7, which has a zero maximum and minimum quotas. However,
when such packets arrive from PG 0 they are admitted to the shared
buffer as PG 0 has a non-zero minimum quota.
Allow all packets to be trapped to the CPU - regardless of the PG they
were classified to - by assigning a 10KB minimum quota for CPU port and
TC7.

One of the conditions to generate an ICMP Redirect Message is that "the
packet is being forwarded out the same physical interface that it was
received from" (RFC 1812).
Therefore, we need to be able to trap such packets and let the kernel
decide what to do with them.
For each RIF, enable the loop-back filter, which will raise the LBERROR
trap whenever the ingress RIF equals the egress RIF.

Add the following traps:
1) MTU Error: Trap packets whose size is bigger than the egress RIF's
MTU. If DF bit isn't set, traffic will continue to be routed in slow
path.
2) TTL Error: Trap packets whose TTL expired. This allows traceroute to
work properly.
3) OSPF packets.

Commit bbf2a4757b30 ("mlxsw: spectrum: Initialize ports at the end of
init sequence") moved ports initialization to the end of the init
sequence, which means ports are the first to be removed during fini.
Since the FDB delayed work is still active when ports are removed it's
possible for it to process FDB notifications of inactive ports,
resulting in a warning message.
Fix that by marking ports as inactive only after unregistering them. The
NETDEV_UNREGISTER event will invoke bridge's driver port removal
sequence that will cause the FDB (and FDB notifications) to be flushed.

After registering a netdevice it's possible for user space applications
to configure an IP address on it. From the driver's perspective, this
means a router interface (RIF) should be created for the PVID vPort.
Therefore, we must create the PVID vPort before registering the
netdevice.

Currently, when device configuration fails we emit errors to the kernel
log despite the fact we already get these from the EMAD transaction
layer, so remove them.
In addition to being unnecessary, removing these error messages will
allow us to reuse mlxsw_sp_port_add_vid() to create the PVID vPort
before registering the netdevice.

When removing a VLAN filter from the device we shouldn't return upon the
first error we encounter, as otherwise we'll have resources that will
never be freed nor used.
Instead, we should keep trying to free as much resources as possible in
a best effort mode.
Remove the error message as well, since we already get these from the
EMAD transaction code.

The raid0 MD personality does not start a raid0 array with any of its
data devices missing.
dm-raid was removing data/metadata device pairs unconditionally if it
failed to read a superblock off the respective metadata device of such
pair, resulting in failure to start arrays with the raid0 personality.
Avoid removing any data/metadata device pairs in case of raid0
(e.g. lvm2 segment type 'raid0_meta') thus allowing MD to start the
array.
Also, avoid region size validation for raid0.

clocksource/mips-gic-timer.c:183:18: warning: ignoring return value of 'PTR_ERR', declared with attribute warn_unused_result [-Wunused-result]
Given that the addition of the return values was intentional, it seems
that the conversion of the containing function from void to int was
simply overlooked.

I could not figure out why, but GCC cannot prove that the
kona_timer_init() function always initializes its two outputs,
and we get a warning for the use of the 'lsw' variable later,
which is obviously correct.
drivers/clocksource/bcm_kona_timer.c: In function 'kona_timer_init':
drivers/clocksource/bcm_kona_timer.c:119:13: error: 'lsw' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Slightly reordering the loop makes the warning disappear, after
it becomes more obvious to the compiler that the loop is
always entered on the first iteration.
As pointed out by Ray Jui, there is a related problem in the
way we deal with the loop running into the limit, as we just
keep going there with an invalid counter data, so instead we
now propagate a -ETIMEDOUT result to the caller.

While converting the init function to return an error, the wrong clock
was get. This leads to the wrong clock rate and slows down the kernel.
For example, it affects typical boot time:
- without fix: over 1 minute
- with fix: 15 seconds

The i40e driver was causing a kernel panic when
non-contiguous Traffic Classes, or Traffic Classes not
starting with TC0, were configured on a link partner switch.
i40e does not support non-contiguous TCs.
To fix this, the patch changes the logic when determining
the total number of TCs enabled. Before, this would use the
highest TC number enabled and assume that all TCs below it were
also enabled. Now, we create a bitmask of enabled TCs and scan
it to determine not only the number of TCs, but also if the set
of enabled TCs starts at zero and is contiguous. If not, then
DCB is disabled by only returning one TC.

attempt_restore_of_faulty_devices() is limited to 64 when it should support
the new maximum of 253 when identifying any failed devices. It clears any
revivable devices via an MD personality hot remove and add cylce to allow
for their recovery.
Address by using existing functions to retrieve and update all failed
devices' bitfield members in the dm raid superblocks on all RAID devices
and check for any devices to clear in it.
Whilst on it, don't call attempt_restore_of_faulty_devices() for any MD
personality not providing disk hot add/remove methods (i.e. raid0 now),
because such personalities don't support reviving of failed disks.
