After range lock is introduced to Lustre, it's possible for
multiple threads to submit osc_extents with partial pages, and
finally I/O engine may try to merge these extents, which will
end up with assert in osc_build_rpc().

In this patch, osc_extent::oe_no_merge is introduced, and this flag
is set if osc_extent submitted via osc_io_submit() includes partial
pages. This flag is used by I/O engine to stop merging this kind
of extents.

This broke when I converted the 32-bit get_seconds() into
ktime_get_{real_,}seconds() inconsistently. Either
one of those two would have worked, but mixing them
does not.

Staying with the original intention of the patch, this
changes the ktime_get_seconds() calls into ktime_get_real_seconds(),
using real time instead of mononic time.

When lu_object_alloc() reaches to LOV object init, we need initialize
its stripe type beforehand, so that if something wrong in the conf

This patch also improves debug messages in lsm_unpackmd_common(), and

So, move it to the struct dvb_usb_device and initialize it
before calling the driver's callbacks.

As found by gcc -Wmaybe-uninitialized, having a storage_bytes value other
than 2 or 4 will result in undefined behavior:

drivers/iio/temperature/maxim_thermocouple.c: In function 'maxim_thermocouple_read':
drivers/iio/temperature/maxim_thermocouple.c:141:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This probably cannot happen, but returning -EINVAL here is appropriate
and makes gcc happy and the code more robust.

aoeblk contains some mysterious code, that wants to elevate the bio
vec page counts while it's under IO. That is not needed, it's
fragile, and it's causing kernel oopses for some.

The ns->lba_shift assumes its value to be the logarithmic of the
LA size. A previous patch duplicated the lba_shift calculation into
lightnvm. It prematurely also subtracted a 512byte shift, which commonly
is applied per-command. The 512byte shift being subtracted twice led to
data loss when restoring the logical to physical mapping table from
device and when issuing I/O commands using rrpc.

Fix offset by removing the 512byte shift subtraction when calculating
lba_shift.

Pull ACPI fix from Rafael Wysocki:
 "Fix a recent regression in the 8250_dw serial driver introduced by
  adding a quirk for the APM X-Gene SoC to it which uncovered an issue
  related to the handling of built-in device properties in the core ACPI
  device enumeration code (Heikki Krogerus)"

Pull power management fixes from Rafael Wysocki:
 "These fix two bugs in error code paths in the PM core (system-wide
  suspend of devices), a device reference leak in the boot-time suspend
  test code and a cpupower utility regression from the 4.7 cycle.

  Specifics:

   - Prevent the PM core from attempting to suspend parent devices if
     any of their children, whose suspend callbacks were invoked
     asynchronously, have failed to suspend during the "late" and
     "noirq" phases of system-wide suspend of devices (Brian Norris).

   - Prevent the boot-time system suspend test code from leaking a
     reference to the RTC device used by it (Johan Hovold).

   - Fix cpupower to use the return value of one of its library
     functions correctly and restore the correct behavior of it when
     used for setting cpufreq tunables broken during the 4.7 development
     cycle (Laura Abbott)"
