9b89fdfee4 Bluetooth: btmrvl: error path handling in setup handler
If module init command fails, FW might not be in good state.
We will return from setup handler and skip downloading further
commands.

8b324fa691 Bluetooth: btmrvl: fix race issue while stopping main thread
btmrvl_remove_card() calls kthread_stop() to stop the main thread,
but kthread_should_stop() is checked when all the activities are done
in the main thread before sleeping.
We will have kthread_should_stop() check as soon as main thread is
woken up. This fixes a crash issue caused due to an invalid memory
access while unnecessarily processing interrupts after card removal.

4fcef8ed75 Bluetooth: Fix issue with Roper Class 1 Bluetooth Dongle
The Roper Class 1 Bluetooth Dongle is another device that claims to
support Bluetooth 1.2 specification, but does not support the HCI
command for reading the local supported commands.

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
      Read Local Version Information (0x04|0x0001) ncmd 1
      status 0x00
      HCI Version: 1.2 (0x2) HCI Revision: 0x0
      LMP Version: 1.2 (0x2) LMP Subversion: 0x757
      Manufacturer: Silicon Wave (11)

It clearly claims Bluetooth 1.2 support and in that regard has the
same issue as the AVM BlueFritz! USB devices (Silicon Wave based),
but the HCI Read Local Supported Commands command fails.

  < HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0
  > HCI Event: Command Status (0x0f) plen 4
      Read Local Supported Commands (0x04|0x0002) status 0x01 ncmd 1
      Error: Unknown HCI Command

Use the HCI_QUIRK_BROKEN_LOCAL_COMMANDS quirk for these devices and
the failing command will be skipped.

41f2f1273c virtio-net: don't do header check for dodgy gso packets
There's no need to do header check for virtio-net since:

- Host sets dodgy for all gso packets from guest and check the header.
- Host should be prepared for all kinds of evil packets from guest, since
  malicious guest can send any kinds of packet.

So this patch sets NETIF_F_GSO_ROBUST for virtio-net to skip the check.

2eebdde652 timecounter: keep track of accumulated fractional nanoseconds
The current timecounter implementation will drop a variable amount
of resolution, depending on the magnitude of the time delta. In
other words, reading the clock too often or too close to a time
stamp conversion will introduce errors into the time values. This
patch fixes the issue by introducing a fractional nanosecond field
that accumulates the low order bits.

Pull thermal management updates from Zhang Rui:
 "First of all, the most important change is the thermal cpu cooling
  fixes.  The major fix here is to have proper sequencing between
  cpufreq layer and thermal cpu cooling registration.  A take away of
  this fix is an improvement in the thermal drivers code.  Thermal
  drivers that require cpu cooling do not need to check for cpufreq
  layer.  The requirement now is to propagate the error code, if any,
  while registering cpu cooling device.  Thanks to Viresh for
  implementing the required CPUfreq changes.

  Second, a new driver is introduced for int340x processor thermal
  device.  Given that int340x thermal is disabled by default, and this
  processor thermal device is only available on limited platforms, plus
  the driver does nothing but exposes some thermal limitation
  information for user space to use, thus I think it is safe to include
  it in this pull request after missing 3.19-rc2.

  Specifics:

   - Thermal cpu cooling fixes and cleanups.

   - introduce INT340X processor thermal reporting device driver.

   - several small fixes and cleanups for int340x thermal drivers"
