Jason Wang 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.

David S. Miller 5115ec9654 Merge branch 'timecounter'
Richard Cochran says:

====================
Time Counter fixes and improvements

Several PTP Hardware Clock (PHC) drivers implement the clock in
software using the timecounter/cyclecounter code. This series adds one
simple improvement and one more subtle fix to the shared timecounter
facility. Credit for this series goes to Janusz Użycki, who pointed
the issues out to me off list.

Patch #1 simply move the timecounter code into its own file. When
working on this series, it was really annoying to see half the kernel
recompile after every tweak to the timecounter stuff. There is no
reason to keep this together with the clocksource code.

Patch #2 implements an improved adjtime() method, and patches 3-10
convert all of the drivers over to the new method.

Patch #11 fixes a subtle but important issue with the timecounter WRT
frequency adjustment. As it stands now, a timecounter based PHC will
exhibit a variable frequency resolution (and variable time error)
depending on how often the clock is read.

In timecounter_read_delta(), the expression

   (delta * cc->mult) >> cc->shift;

can lose resolution from the adjusted value of 'mult'. If the value
of 'delta' is too small, then small changes in 'mult' have no effect.
However, if the delta value is large enough, then small changes in
'mult' will have an effect.

Reading the clock too often means smaller 'delta' values which in turn
will spoil the fine adjustments made to 'mult'. Up until now, this
effect did not show up in my testing. The following example explains
why.

The CPTS has an input clock of 250 MHz, and the clock source uses
mult=0x80000000 and shift=29, making the ticks to nanoseconds
conversion like this:

   ticks * 2^31
   ------------
       2^29

Imagine what happens if the clock is read every 10 milliseconds. Ten
milliseconds are about 2500000 ticks, which corresponds to about 21
bits. The product in the numerator has then 52 bits. After the shift
operation, 23 bits are preserved. This results in a frequency
adjustment resolution of about 0.1 ppm (not _too_ bad.)

A frequency resolution of 1 ppm requires 20 bits.
A frequency resolution of 1 ppb requires 30 bits.

For the 250 MHz CPTS clock, reading every 4 seconds yields a 1 ppb
resolution (which is the finest that our API allows).

However, the error can be much higher if the clock is read too often
or if time stamps occur close in time to read operations. In general
it is really not acceptable to allow the rate of clock readings to
influence the clock accuracy.

Richard Cochran 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.

Richard Cochran 796c1efd6f timecounter: provide a helper function to shift the time.
Some PTP Hardware Clock drivers use a struct timecounter to represent
their clock. To adjust the time by a given offset, these drivers all
perform a two step read/write of their timecounter. However, it is
better and simpler just to adjust the offset in one step. This patch
introduces a little routine to help drivers implement the adjtime
method.

Pull power management and ACPI material from Rafael J Wysocki:
 "These are fixes (operating performance points library, cpufreq-dt
  driver, cpufreq core, ACPI backlight, cpupower tool), cleanups
  (cpuidle), new processor IDs for the RAPL (Running Average Power
  Limit) power capping driver, and a modification of the generic power
  domains framework allowing modular drivers to call one of its helper
  functions.

  Specifics:

   - Fix for a potential NULL pointer dereference in the cpufreq core
     due to an initialization race condition (Ethan Zhao).

   - Fixes for abuse of the OPP (Operating Performance Points) API
     related to RCU and other minor issues in the OPP library and the
     cpufreq-dt driver (Dmitry Torokhov).

   - cpuidle governors cleanup making them measure idle duration in a
     better way without using the CPUIDLE_FLAG_TIME_INVALID flag which
     allows that flag to be dropped from the ACPI cpuidle driver and
     from the core too (Len Brown).

   - New ACPI backlight blacklist entries for Samsung machines without a
     working native backlight interface that need to use the ACPI
     backlight instead (Aaron Lu).

   - New CPU IDs of future Intel Xeon CPUs for the Intel RAPL power
     capping driver (Jacob Pan).

   - Generic power domains framework modification to export the
     of_genpd_get_from_provider() function to modular drivers that will
     allow future driver modifications to be based on the mainline (Amit
     Daniel Kachhap).

   - Two fixes for the cpupower tool (Michal Privoznik, Prarit
     Bhargava)"

David S. Miller dc97a1a947 genetlink: A genl_bind() to an out-of-range multicast group should not WARN().
Users can request to bind to arbitrary multicast groups, so warning
when the requested group number is out of range is not appropriate.

And with the warning removed, and the 'err' variable properly given
an initial value, we can remove 'found' altogether.

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"

Michal Hocko 45f87de57f mm: get rid of radix tree gfp mask for pagecache_get_page
Commit 2457aec637 ("mm: non-atomically mark page accessed during page
cache allocation where possible") has added a separate parameter for
specifying gfp mask for radix tree allocations.

Not only this is less than optimal from the API point of view because it
is error prone, it is also buggy currently because
grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
the radix tree allocation wouldn't obey the restriction and might
recurse into filesystem and cause deadlocks.  This is the case for most
filesystems unfortunately because only ext4 and gfs2 are using
AOP_FLAG_NOFS.

Let's simply remove radix_gfp_mask parameter because the allocation
context is same for both page cache and for the radix tree.  Just make
sure that the radix tree gets only the sane subset of the mask (e.g.  do
not pass __GFP_WRITE).

Long term it is more preferable to convert remaining users of
AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
interface even further.
