pull-request: bpf-next 2018-01-11
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Various BPF related improvements and fixes to nfp driver: i) do
not register XDP RXQ structure to control queues, ii) round up
program stack size to word size for nfp, iii) restrict MTU changes
when BPF offload is active, iv) add more fully featured relocation
support to JIT, v) add support for signed compare instructions to
the nfp JIT, vi) export and reuse verfier log routine for nfp, and
many more, from Jakub, Quentin and Nic.
2) Fix a syzkaller reported GPF in BPF's copy_verifier_state() when
we hit kmalloc failure path, from Alexei.
3) Add two follow-up fixes for the recent XDP RXQ series: i) kvzalloc()
allocated memory was only kfree()'ed, and ii) fix a memory leak where
RX queue was not freed in netif_free_rx_queues(), from Jakub.
4) Add a sample for transferring XDP meta data into the skb, here it
is used for setting skb->mark with the buffer from XDP, from Jesper.

Currently intel_pstate can function only in HWP mode on Skylake servers.
When HWP feature is not enabled on the processor then acpi-cpufreq is
driver is used.
Based on the power and performance tests using intel_pstate scaling
algorithm the results are comparable. But intel_pstate brings in
additional features:
- Display of turbo frequency range, which many users like to see
- Place limits in the turbo frequency range when platform allows
Since these tests are done only using non PID algorithm introduced in
kernel version 4.14, this patch is not a backport candidate. So each user
has to carefully weigh the benefits before he backports.

Some systems don't support the ACPI_LPS0_ENTRY and ACPI_LPS0_EXIT
functions in their Low Power S0 Idle _DSM, but still expect EC
events to be processed in the suspend-to-idle state for power button
wakeup (among other things) to work. Surface Pro3 turns out to be
one of them.
Fortunately, it still provides Low Power S0 Idle _DSM with the screen
on/off functions supported, so modify the ACPI suspend-to-idle to use
the Low Power S0 Idle code path for all systems supporting the
ACPI_LPS0_ENTRY and ACPI_LPS0_EXIT or the ACPI_LPS0_SCREEN_OFF and
ACPI_LPS0_SCREEN_ON functions in their Low Power S0 Idle _DSM.
Potentially, that will cause more systems to use suspend-to-idle by
default, so some future corrections may be necessary if it leads
to issues, but let it remain more straightforward for now.

In general, wakeup settings are not supposed to be changed during any of
the system wide PM phases. The reason is simply that it would break
guarantees provided by the PM core, to properly act on active wakeup
sources.
However, there are exceptions to when, in particular, disabling a device as
wakeup source makes sense. For example, in cases when a driver realizes
that its device is dead during system suspend. For these scenarios, we
don't need to care about acting on the wakeup source correctly, because a
dead device shouldn't deliver wakeup signals.
To this reasoning and to help users to properly manage wakeup settings,
let's print a warning in cases someone calls device_wakeup_enable() during
system sleep.

The reason seems to be that the chip is not properly reset.

40GbE Intel Wired LAN Driver Updates 2018-01-10
This series contains updates to i40e and i40evf only.
Alice adds the displaying of priority xon/xoff packet stats, since we
were already keeping track of them. Based on the recent changes, bump
the driver versions.
Jake changes how the driver determines whether or not the device is
currently up to resolve the possible issue of freeing data structures
and other memory before they have been fully allocated. Refactored
the driver to simplify the locking behavior and to consistently use
spinlocks instead of an overloaded bit lock to protect MAC and filter
lists. Created a helper function which can convert the AdminQ link
speed definition into a virtchnl definition.
Colin Ian King cleans up a redundant variable initialization.
Alex cleans up the driver to stop clearing the pending bit array for
each vector manually, since it is prone to dropping an interrupt and
based on the hardware specs, the pending bit array will be cleared
automatically in MSI-X mode. Cleaned up flags for promiscuous mode to
resolve an issue where enabling & disabling promiscuous mode on a VF
would leave us in a high polling rate for the adminq task. Cleaned up
code that was prone to race issues.
Jingjing renames pipeline personalization profile (ppp) to dynamic
device personalization (ddp) because it was being confused with the
well known point to point protocol. Also removed checks for "track_id"
being zero, since it is valid for it to be zero for profiles that do
not have any 'write' commands.
v2: cleaned up commit message for patch 12 based on feedback from Sergei
Shtylyov and Alex Duyck

Given that mmc_of_parse() has already been made ACPI/DT agnostic,
making the SDH30 driver ACPI capable is actually rather simple:
all we need to do is make the call to sdhci_get_of_property() [which

(e.g. if rounded is 2 * ideal) that the condition
"abs(rate - rounded / i) < abs(rate - best_parent / best_div)" is never
