Mika Westerberg 38a529b5d4 e1000e: Fix compilation warning when !CONFIG_PM_SLEEP
Commit 7509963c70 (e1000e: Fix a compile flag mis-match for
suspend/resume) moved suspend and resume hooks to be available when
CONFIG_PM is set. However, it can be set even if CONFIG_PM_SLEEP is not set
causing following warnings to be emitted:

drivers/net/ethernet/intel/e1000e/netdev.c:6178:12: warning:
  	‘e1000_suspend’ defined but not used [-Wunused-function]

drivers/net/ethernet/intel/e1000e/netdev.c:6185:12: warning:
	‘e1000_resume’ defined but not used [-Wunused-function]

To fix this make the hooks to be available only when CONFIG_PM_SLEEP is set
and remove CONFIG_PM wrapping from driver ops because this is already
handled by SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS().

When Intel MID finds a match between SFI table from FW and registered
SFI devices, it will always register a device regardless the platform
code was successful or not.

This patch adds an extra option for platform code to return error code
and abort device registration on SFI table parsing.

Srinivas Pandruvada 875e36f8a2 HID: hid-sensor-hub: Fix buggy report descriptors
This addresses regression caused by commit id "751d17e23a9f7"
 iio: hid-sensors: Fix power and report state.
This commit removed a quirk, to change the enumeration base
to 1 from 0 based on an CONFIG paramter. There was objection to
add more changes under this quirk, instead suggested to add an
HID quirk. But there is no easy way to add HID qurik as the
reports are not properly using collection class.

The solution was to use logical minimum, which is a correct way.
There were changes done in firmware to address this.

Unfortunately some devices, still use old FW and can't be upgraded
to newer version on Linux devices as there is no FW upgrade tool
available for Linux devices. So we need to fix report descriptors,
for such devices. This will not have any impact, if the FW uses
logical 1 as minimum.

In this patch we look for usage id for "power and report state", and
modify logical minimum value to 1.

Background on enum:
In the original HID sensor hub firmwares all Named array enums were
to 0-based. But the most recent hub implemented as 1-based,
because of the implementation by one of the major OS vendor.
Using logical minimum for the field as the base of enum. So we add
logical minimum to the selector values before setting those fields.
Some sensor hub FWs already changed logical minimum from 0 to 1
to reflect this and hope every other vendor will follow.
There is no easy way to add a common HID quirk for NAry elements,
even if the standard specifies these field as NAry, the collection
used to describe selectors is still just "logical".

Benjamin Tisssoires 42c22dbf81 HID: logitech-dj: Fix USB 3.0 issue
This fix (not very clean though) should fix the long time USB3
issue that was spotted last year. The rational has been given by
Hans de Goede:

 ----

I think the most likely cause for this is a firmware bug
in the unifying receiver, likely a race condition.

The most prominent difference between having a USB-2 device
plugged into an EHCI (so USB-2 only) port versus an XHCI
port will be inter packet timing. Specifically if you
send packets (ie hid reports) one at a time, then with
the EHCI controller their will be a significant pause
between them, where with XHCI they will be very close
together in time.

The reason for this is the difference in EHCI / XHCI
controller OS <-> driver interfaces.

For non periodic endpoints (control, bulk) the EHCI uses a
circular linked-list of commands in dma-memory, which it
follows to execute commands, if the list is empty, it
will go into an idle state and re-check periodically.

The XHCI uses a ring of commands per endpoint, and if the OS
places anything new on the ring it will do an ioport write,
waking up the XHCI making it send the new packet immediately.

For periodic transfers (isoc, interrupt) the delay between
packets when sending one at a time (rather then queuing them
up) will be even larger, because they need to be inserted into
the EHCI schedule 2 ms in the future so the OS driver can be
sure that the EHCI driver does not try to start executing the
time slot in question before the insertion has completed.

So a possible fix may be to insert a delay between packets
being send to the receiver.

 ----

I tested this on a buggy Haswell USB 3.0 motherboard, and I always
get the notification after adding the msleep.

Frederic Weisbecker 3178f58b98 perf tools: Do proper comm override error handling
The comm overriding API ignores memory allocation failures by silently
keeping the previous and out of date comm.

As a result, the user may get buggy events without ever being notified
about the problem and its source.

Lets start to fix this by propagating the error from the API. Not all
callers may be doing proper error handling on comm set yet but this is
the first step toward it.

Mike Snitzer 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

Peter Zijlstra 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.

Tejun Heo 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.

Heiko Carstens 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.
