2e68c4e6ca dm cache: add policy name to status output
The cache's policy may have been established using the "default" alias,
which is currently the "mq" policy but the default policy may change in
the future.  It is useful to know exactly which policy is being used.

Add a 'real' member to the dm_cache_policy_type structure and have the
"default" dm_cache_policy_type point to the real "mq"
dm_cache_policy_type.  Update dm_cache_policy_get_name() to check if
real is set, if so report the name of the real policy (not the alias).

The above commit breaks the mapping type for Device memory because
pgprot_default already contains a Normal memory type. pgprot_default is
also not initialised early enough for earlyprintk resulting in an
inconsistent memory mapping with 64K PAGE_SIZE configuration.

42ccd781bb of: Fix __of_device_is_available check
From IEEE 1275, there defined a standard 'status' property indicating the
operational status of one device. The 'status' property has four possible
values: 'okay/ok', 'disabled', 'fail' and 'fail-xxx'.

If it is absent, that means the status of the device is unknown or okay.

The __of_device_is_available checks the state of the 'status' property of
a device. If the property is absent or set to 'okay/ok', it returns 1.
Otherwise it returns 0.

While in __of_device_is_available:
 >	status = of_get_property(device, "status", &statlen);
 >	if (status == NULL)
 >		return 1;
The status value returned from 'of_get_property()' will be NULL in two cases:
Firstly: the 'device' value (device node) is NULL.
Secondly: the 'status' property is actaully not exist.

If the device node is NULL, the __of_device_is_available will return true,
that will mean the absent state of the 'status' property.

So this add the device node check before checking the 'status' property's
state, and if the device node is not exist, 0 will be returned.

eaad45132c sched: Fix __sched_setscheduler() nice test
With the introduction of sched_attr::sched_nice we need to check
if we've got permission to actually change the nice value.

Daniel found that can_nice() would always fail; and upon
inspection it turns out that can_nice() only tests to see if we
can lower the nice value, but it doesn't validate if we're
lowering or not.

Therefore amend the test to only call can_nice() when we lower
the nice value.

f28d7de6bd ARM: orion: provide C-style interrupt handler for MULTI_IRQ_HANDLER
DT-enabled Marvell Kirkwood and Dove SoCs make use of an irqchip
driver. As expected for irqchip drivers, it uses a C-style
interrupt handler and therefore selects MULTI_IRQ_HANDLER.

Now, compiling a kernel with both non-DT and DT support enabled,
selecting MULTI_IRQ_HANDLER will break ASM irq handler used by
non-DT boards.

Therefore, we provide a C-style irq handler even for non-DT boards,
if MULTI_IRQ_HANDLER is set. By installing the C-style irq handler
in orion_irq_init this is transparent to all non-DT board files.

While the regression report was filed on Marvell Kirkwood, also
Marvell Dove non-DT boards are affected and fixed by this patch.

351291754d dt/bindings: remove device_type "network" references
device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).

This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

a015c1e926 iommu/amd: fix accounting of device_state
This patch fixes a bug in the accounting of the device_state.
In the current code, the device_state was put (decremented) too many times,
which sometimes lead to the driver getting stuck permanently in
put_device_state_wait(). That happen because the device_state->count would go
below zero, which is never supposed to happen.

The root cause is that the device_state was decremented in put_pasid_state()
and put_pasid_state_wait() but also in all the functions that call those
functions. Therefore, the device_state was decremented twice in each of these
code paths.

The fix is to decouple the device_state accounting from the pasid_state
accounting - remove the call to put_device_state() from the
put_pasid_state() and the put_pasid_state_wait())

1897bdc4d3 mmu_notifier: add mmu_notifier_invalidate_range()
This notifier closes an important gap in the current mmu_notifier
implementation, the existing callbacks are called too early or too late to
reliably manage a non-CPU TLB.  Specifically, invalidate_range_start() is
called when all pages are still mapped and invalidate_range_end() when all
pages are unmapped and potentially freed.

This is fine when the users of the mmu_notifiers manage their own SoftTLB,
like KVM does.  When the TLB is managed in software it is easy to wipe out
entries for a given range and prevent new entries to be established until
invalidate_range_end is called.

But when the user of mmu_notifiers has to manage a hardware TLB it can
still wipe out TLB entries in invalidate_range_start, but it can't make
sure that no new TLB entries in the given range are established between
invalidate_range_start and invalidate_range_end.

To avoid silent data corruption the entries in the non-CPU TLB need to be
flushed when the pages are unmapped (at this point in time no _new_ TLB
entries can be established in the non-CPU TLB) but not yet freed (as the
non-CPU TLB may still have _existing_ entries pointing to the pages about
to be freed).

To fix this problem we need to catch the moment when the Linux VMM flushes
remote TLBs (as a non-CPU TLB is not very CPU TLB), as this is the point
in time when the pages are unmapped but _not_ yet freed.

The mmu_notifier_invalidate_range() function aims to catch that moment.

IOMMU code will be one user of the notifier-callback.  Currently this is
only the AMD IOMMUv2 driver, but its code is about to be more generalized
and converted to a generic IOMMU-API extension to fit the needs of similar
functionality in other IOMMUs as well.

The current attempt in the AMD IOMMUv2 driver to work around the
invalidate_range_start/end() shortcoming is to assign an empty page table
to the non-CPU TLB between any invalidata_range_start/end calls.  With the
empty page-table assigned, every page-table walk to re-fill the non-CPU
TLB will cause a page-fault reported to the IOMMU driver via an interrupt,
possibly causing interrupt storms.

The page-fault handler in the AMD IOMMUv2 driver doesn't handle the fault
if an invalidate_range_start/end pair is active, it just reports back
SUCCESS to the device and let it refault the page.  But existing hardware
(newer Radeon GPUs) that makes use of this feature don't re-fault
indefinitly, after a certain number of faults for the same address the
device enters a failure state and needs to be resetted.

To avoid the GPUs entering a failure state we need to get rid of the
empty-page-table workaround and use the mmu_notifier_invalidate_range()
function introduced with this patch.

ASoC: Fixes for v3.13

A few small fixes in drivers, nothing too remarkable here but all good
to have - mainly these are fixes for things that were introduced in the
last merge window but only just got useful testing.

ecd75ad514 libata: disable LPM for some WD SATA-I devices
For some reason, some early WD drives spin up and down drives
erratically when the link is put into slumber mode which can reduce
the life expectancy of the device significantly.  Unfortunately, we
don't have full list of devices and given the nature of the issue it'd
be better to err on the side of false positives than the other way
around.  Let's disable LPM on all WD devices which match one of the
known problematic model prefixes and are SATA-I.

As horkage list doesn't support matching SATA capabilities, this is
implemented as two horkages - WD_BROKEN_LPM and NOLPM.  The former is
set for the known prefixes and sets the latter if the matched device
is SATA-I.

Note that this isn't optimal as this disables all LPM operations and
partial link power state reportedly works fine on these; however, the
way LPM is implemented in libata makes it difficult to precisely map
libata LPM setting to specific link power state.  Well, these devices
are already fairly outdated.  Let's just disable whole LPM for now.

63b1a81699 futexes: Fix futex_hashsize initialization
"futexes: Increase hash table size for better performance"
introduces a new alloc_large_system_hash() call.

alloc_large_system_hash() however may allocate less memory than
requested, e.g. limited by MAX_ORDER.

Hence pass a pointer to alloc_large_system_hash() which will
contain the hash shift when the function returns. Afterwards
correctly set futex_hashsize.

Fixes a crash on s390 where the requested allocation size was
4MB but only 1MB was allocated.

382cebb02a spi/pxa2xx: fix compilation warning when !CONFIG_PM_SLEEP
CONFIG_PM will be set if either or both CONFIG_PM_SLEEP and
CONFIG_PM_RUNTIME is set. Compiling the driver with !CONFIG_PM_SLEEP causes
following compilation warning:

drivers/spi/spi-pxa2xx.c:1270:12: warning: ‘pxa2xx_spi_suspend’ defined but not used [-Wunused-function]

Fix this by using CONFIG_PM_SLEEP instead.

When we plug a 3-ring headset on some Dell machines, the headset
mic can't be detected, after apply this patch, the headset mic
can work well on all those machines.

On the machine with the Subsytem ID 0x10280610, if we use
ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, the headset mic can be
detected and work well, but the sound can't be outputed via
headphone anymore, use ALC269_FIXUP_DELL3_MIC_NO_PRESENCE
can fix this problem.

40aad3c1a9 dt/bindings: Remove all references to device_type "ethernet-phy"
The device_type property is deprecated for the flattened device tree and
the value "ethernet-phy" has never been defined as having a useful
meaning. Neither the kernel nor u-boot depend on it. It should never
have appeared in PHY bindings. This patch removes all references to
"ethernet-phy" as a device_type value from the documentation and the
.dts files.

This patch was generated mechanically with the following command and
then verified by looking at the diff.

sed -i '/"ethernet-phy"/d' `git grep -l '"ethernet-phy"'`
