2019-03-12i2c: mediatek: modify threshold passed to i2c_get_dma_safe_msg_buf()Hsin-Yi Wang
DMA with zero-length transfers doesn't make sense and this HW doesn't support them at all, so increase the threshold.

2019-03-12ACPI: sysfs: Prevent get_status() from returning acpi_statusRafael J. Wysocki
The return value of get_status() is passed to user space on errors, so it should not return acpi_status values then. Make it return error values that are meaningful for user space instead. This also makes a Clang warning regarding the initialization of a local variable in get_status() go away.

2019-03-12cpufreq: intel_pstate: Fix up iowait_boost computationRafael J. Wysocki
After commit b8bd1581aa61 ("cpufreq: intel_pstate: Rework iowait boosting to be less aggressive") the handling of the case when the SCHED_CPUFREQ_IOWAIT flag is set again after a few iterations of intel_pstate_update_util() is a bit inconsistent, because the new value of cpu->iowait_boost may be lower than ONE_EIGHTH_FP if it was set before, but has not dropped down to zero just yet. Fix that up by ensuring that the new value of cpu->iowait_boost will always be at least ONE_EIGHTH_FP then.

2019-03-12PM / OPP: Update performance state when freq == old_freqViresh Kumar
At boot up, CPUFreq core performs a sanity check to see if the system is running at a frequency defined in the frequency table of the CPU. If so, we try to find a valid frequency (lowest frequency greater than the currently programmed frequency) from the table and set it. When the call reaches dev_pm_opp_set_rate(), it calls _find_freq_ceil(opp_table, &old_freq) to find the previously configured OPP and this call also updates the old_freq. This eventually sets the old_freq == freq (new target requested by cpufreq core) and we skip updating the performance state in this case. Fix this by also updating the performance state when the old_freq == freq.

After commit d856f39ac1cc ("PM / wakeup: Rework wakeup source timer cancellation") wakeup_source_drop() is a trivial wrapper around __pm_relax() and it has no users except for wakeup_source_destroy() and wakeup_source_trash() which also has no users, so drop it along with the latter and make wakeup_source_destroy() call __pm_relax() directly.

2019-03-12PM / wakeup: Rework wakeup source timer cancellationViresh Kumar
If wakeup_source_add() is called right after wakeup_source_remove() for the same wakeup source, timer_setup() may be called for a potentially scheduled timer which is incorrect. To avoid that, move the wakeup source timer cancellation from wakeup_source_drop() to wakeup_source_remove(). Moreover, make wakeup_source_remove() clear the timer function after canceling the timer to let wakeup_source_not_registered() treat unregistered wakeup sources in the same way as the ones that have never been registered.

2019-03-11lan743x: Fix RX Kernel PanicBryan Whitehead
It has been noticed that running the speed test at www.speedtest.net occasionally causes a kernel panic. Investigation revealed that under this test RX buffer allocation sometimes fails and returns NULL. But the lan743x driver did not handle this case. This patch fixes this issue by attempting to allocate a buffer before sending the new rx packet to the OS. If the allocation fails then the new rx packet is dropped and the existing buffer is reused in the DMA ring. Updates for v2: Additional 2 locations where allocation was not checked, has been changed to reuse existing buffer.

2019-03-11net/mlx5e: Properly get the PF number phys port name ndoRoi Dayan
Currently, we fail to retrieve the PF number in some cases (e.g single ported cards, lag capability), this further results in a call trace issued by the rtnetlink code, since the error value is not -EOPNOTSUPP. Change the implementation to be independent from the lag code and function properly on both two ports and single ported cards.

2019-03-11net/mlx5: Consolidate update FTE for all removal changesEli Britstein
With commit a18e879d4e45 ("net/mlx5e: Annul encap action ordering requirement") and a use-case of e-switch remote mirroring, the incremental/stepped FTE removal process done by the fs core got us to illegal transient states and FW errors: SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x9c2e40) To avoid that and improve FTE removal performance, aggregate the FTE's updates that should be applied. Remove the FTE if it is empty, or apply one FW update command with the aggregated updates.
