Pull scheduler updates from Ingo Molnar:
"The main changes in this (fairly busy) cycle were:
- There was a class of scheduler bugs related to forgetting to update
the rq-clock timestamp which can cause weird and hard to debug
problems, so there's a new debug facility for this: which uncovered
a whole lot of bugs which convinced us that we want to keep the
debug facility.

- Various cputime related updates: eliminate cputime and use u64
nanoseconds directly, simplify and improve the arch interfaces,
implement delayed accounting more widely, etc. - (Frederic
Weisbecker)
- Move code around for better structure plus cleanups (Ingo Molnar)

Pull perf updates from Ingo Molnar:
"On the kernel side the main changes in this cycle were:
- Add Intel Kaby Lake CPU support (Srinivas Pandruvada)
- AMD uncore driver updates for fam17 (Janakarajan Natarajan)
- Intel/PT updates and core events optimizations and cleanups
(Alexander Shishkin)
- cgroups events fixes (David Carrillo-Cisneros)
- kprobes improvements (Masami Hiramatsu)
- ... plus misc fixes and updates.
On the tooling side the main changes were:
- Support clang build in tools/{perf,lib/{bpf,traceevent,api}} with
CC=clang, to, for instance, take advantage of better warnings
(Arnaldo Carvalho de Melo):
- Introduce the 'delta-abs' 'perf diff' compute method, that orders
the histogram entries by the absolute value of the percentage delta
for a function in two perf.data files, i.e. the functions that
changed the most (increase or decrease in samples) comes first
(Namhyung Kim)
- Add support for parsing Intel uncore vendor event files and add
uncore vendor events for the Intel server processors (Haswell,
Broadwell, IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE
(Andi Kleen)
- Introduce 'perf ftrace' a perf front end to the kernel's ftrace
function and function_graph tracer, defaulting to the
"function_graph" tracer, more work will be done in reviving this
effort, forward porting it from its initial patch submission
(Namhyung Kim)
- Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)
- Account thread wait time (off CPU time) separately: sleep, iowait
and preempt, based on the prev_state of the last event, show the
breakdown when using "perf sched timehist --state" (Namhyumg Kim)
- Add more triggers to switch the output file (perf.data.TIMESTAMP).
Now, in addition to switching to a different output file when
receiving a SIGUSR2, one can also specify file size and time based
triggers:
perf record -a --switch-output=signal
is equivalent to what we had before:
perf record -a --switch-output
While we can also ask for the file to be "sliced" by size, taking
into account that that will happen only when we get woken up by the
kernel, i.e. one has to take into account the --mmap-pages (the
size of the perf mmap ring buffer):
perf record -a --switch-output=2G
will break the perf.data output into multiple files limited to 2GB
of samples, right when generating the output.
For time based samples, alert() will be used, so to have 1 minute
limited perf.data output files:
perf record -a --switch-output=1m
(Jiri Olsa)
- Improve 'perf trace' (Arnaldo Carvalho de Melo)
- 'perf kallsyms' toy tool to look for extended symbol information on
the running kernel and demonstrate the machine/thread/symbol APIs
for use in other tools, such as 'perf probe' (Arnaldo Carvalho de
Melo)
- ... plus tons of other changes, see the shortlog and Git log for
details"
* 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (131 commits)

nfp: expose more firmware and hw debug info
This series is mostly a result of flash firmware team requesting
access to some of the information and data necessary for debugging
firmware problems. Patch 1 adds a missing error message. Patch 2
prints manufacturing info to logs in case PCI VPD capability is
not programmed correctly. Patches 3 and 4 allow reporting NSP ABI
version in ethtool -i. Patch 5 allows dumping flash application
logs.
Patches 6 and 7 provides a way of application firmwares to declare
limited SR-IOV support.
v2: put some of the code in patch 7 in #ifdef CONFIG_PCI_SRIOV (Yuval).

Some application firmware projects may choose to limit the number
of VFs available below what is specified in PCI capability to be
able to reuse the PCIe interface resources. There may also be
projects which use cases don't require SR-IOV support at all and
therefore don't want to spend time implementing/testing it.
Check nfd_vf_cfg_max_vfs firmware symbol to see if application
firmware is reporting how many VFs it supports. This mechanism
is an opt-in, if symbol is not present we will only look at the
PCI capability values.

40GbE Intel Wired LAN Driver Updates 2017-02-18
This series contains updates to i40e and i40evf only.
Alan fixes a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters. Ractored
the '%*ph' printk format specifier to instead use the print_hex_dump().
Josh adds enabling multicast magic packet wakeup by adding calls to
the mac_address_write admin q function during power down to update the
PRTPM_SAH/SAL registers with the MC_MAG_EN bit.
Jake remove a duplicate call i40e_update_link_info(), since it does not
need to call it twice. Fixes and issue where we calculating the wrong
switch id on big endian platforms. Avoided sparse warning, by doing a
typecast to ensure the value is of the type expected by
csum_replace_by_diff().
Mitch fixes a memory leak by freeing resources during i40e_remove().
Cleans up some code confusion by adding a proper code comment.
Carolyn fixes a bug introduced with the addition of the per queue ITR
feature support in ethtool. Cleans up a duplicate device id from the
PCI table.
Harshitha fixes a bug which causes the 'Link Detected' field in
ethtool to report the correct link status.

Resizing currently drops consumer lock. This can cause entries to be
reordered, which isn't good in itself. More importantly, consumer can
detect a false ring empty condition and block forever.
Further, nesting of consumer within producer lock is problematic for
tun, since it produces entries in a BH, which causes a lock order
reversal:
CPU0 CPU1
---- ----
consume:
lock(&(&r->consumer_lock)->rlock);
resize:
local_irq_disable();
lock(&(&r->producer_lock)->rlock);
lock(&(&r->consumer_lock)->rlock);
<Interrupt>
produce:
lock(&(&r->producer_lock)->rlock);
To fix, nest producer lock within consumer lock during resize,
and keep consumer lock during the whole swap operation.

sctp: support MSG_MORE flag when sending msg
This patch is to add support for MSG_MORE on sctp. Patch 1/2 is an
improvement ahead of patch 2/2 to solve the close block problem
mentioned in https://patchwork.ozlabs.org/patch/372404/.

This patch is to add support for MSG_MORE on sctp.
It adds force_delay in sctp_datamsg to save MSG_MORE, and sets it after
creating datamsg according to the send flag. sctp_packet_can_append_data
then uses it to decide if the chunks of this msg will be sent at once or
delay it.
Note that unlike [1], this patch saves MSG_MORE in datamsg, instead of
in assoc. As sctp enqueues the chunks first, then dequeue them one by
one. If it's saved in assoc,the current msg's send flag (MSG_MORE) may
affect other chunks' bundling.
Since last patch, sctp flush out queue once assoc state falls into
SHUTDOWN_PENDING, the close block problem mentioned in [1] has been
solved as well.

This patch is to flush out queue when assoc state falls into
SHUTDOWN_PENDING if there are still chunks in it, so that the
data can be sent out as soon as possible before sending SHUTDOWN
chunk.
When sctp supports MSG_MORE flag in next patch, this improvement
can also solve the problem that the chunks with MSG_MORE flag
may be stuck in queue when closing an assoc.

Both functions aq_ring_rx_deinit() and aq_ring_tx_clean() are almost
identical aside from an additional check in the latter.
Move that check from the function into its caller and replace
aq_ring_rx_deinit() with aq_ring_rx_deinit().
By doing this also adjust the functions return value from int to void
since it can never fail.

net: phy: Fix PHY unbind crash
This fixes crashes when the PHY driver is no longer bound to the device.
There is still a fair amount of work to be done to get the unbind -> bind
sequent to result in a functional state, but that will be net-next material.
These two problems existed for as long as PHYLIB as been around.

There are number of function calls, originating from user-space,
typically through the Ethernet driver that can make us crash by
dereferencing phydev->drv which will be NULL once we unbind the driver
from the PHY.
There are still functional issues that prevent an unbind then rebind to
work, but these will be addressed separately.

The PHY library does not deal very well with bind and unbind events. The first
thing we would see is that we were not properly canceling the PHY state machine
workqueue, so we would be crashing while dereferencing phydev->drv since there
is no driver attached anymore.
