9870d78095 perf ordered_samples: Remove references to perf_{evlist,tool} and machines
As these can be obtained from the ordered_events pointer, via
container_of, reducing the cross section of ordered_samples.

These were added to ordered_samples in:

 commit b7b61cbebd
 Author: Arnaldo Carvalho de Melo <acme@redhat.com>
 Date:   Tue Mar 3 11:58:45 2015 -0300

    perf ordered_events: Shorten function signatures

    By keeping pointers to machines, evlist and tool in ordered_events.

But that was more a transitional patch while moving stuff out from
perf_session.c to ordered_events.c and possibly not even needed by then,
as we could use the container_of() method and instead of having the
nr_unordered_samples stats in events_stats, we can have it in
ordered_samples.

aae59fab97 perf session: Always initialize ordered_events
Even when it is not used to actually reorder events, some of its fields
are used, like session->ordered_events->tool, to shorten function
signatures where tool, for instance, was being passed, as the tool is
needed for the ordered_events code, we need it there and might as well
use it for other perf_session needs.

This fixes a problem where 'perf script' had some condition that made
session->ordered_events not to be initialized even with its
script->tool ordered_events related flags asking for it to be, which
looks like another bug and needs to be investigated further.

Always initializing session->ordered_events at least leaves the current
assumptions in place, so do it now.

73dbcd6537 perf callchain: Fix kernel symbol resolution by remembering the cpumode
Commit 2e77784bb7 ("perf callchain: Move cpumode resolve code to
add_callchain_ip") promised "No change in behavior.".

As this commit breaks callchains on s390x (symbols not getting resolved,
observed when profiling the kernel), this statement is wrong. The cpumode
must be kept when iterating over all ips, otherwise the default
(PERF_RECORD_MISC_USER) will be used by error.

====================
net/macb: fixes after big driver update

The recent modifications to the macb driver lead to issues with the probe
function code flow. Here are some attempt to fix them.
This time, some more issues are fixed related to the clock as reported by Boris
Brezillon.

The series is written on top of net-next.

Changes in v2:
- address Cyrille comment about exit condition of queue configuration loop
- add fixes for probe sequence related to clocks
- add ethtool register dump
- fix peripheral version test

Fix this in macb_configure_caps() so that xilinx ZynqMP will be considered

c69618b3e4 net/macb: fix probe sequence to setup clocks earlier
As accessing the peripheral registers need the clocks to be set, we have to
enable them as soon as possible. Their configuration depend on the type of
device used and determined by the DT compatible string. That lead to add
another initialization function in the DT configuration structure.
As the device private structure length depend on an information read in the
registers, we have to store the clock pointers in temporary variables before
feeding the structure fields.

Capabilities configuration by macb_configure_caps() was moved far too late by
421d9df062 (net/macb: merge at91_ether driver into macb driver) which would

So, move this function to early probe and modify its prototype to re-gain its
original behavior.
DT data retrieval is also moved to simplify the probe code flow.

When merging at91_ether and macb driver during 421d9df062 (net/macb: merge

dealing with initialization of queues is now moved in macb_init() which needs

needed in macb_init().

We've been refusing ACLs that DENY permissions that we can't effectively

Andreas points out that any DENY of Window's "read", "write", or

So maybe we should be a little less paranoid, and ignore entirely the
permissions that are meaningless to us.

displayed to the user in ethtool. The bitmask is u64, therefore we are
limited for a selective view of up to 64 statistics. Extend the bitmap
in order to show more than 64 statistics.

In addition, add packet statistics to the ethtool display for PF.

7f62fe8a58 HSI: cmt_speech: Add cmt-speech driver
Introduces the cmt-speech driver, which implements
a character device interface for transferring speech
data frames over HSI/SSI.

The driver is used to exchange voice/speech data between
the Nokia N900/N950/N9's modem and its cpu.

Since the original driver has been written for 2.6.28 some
build fixes and general cleanups have been added by me:

 * fix build for 4.0 kernel
 * replace GFP_ATOMIC with GFP_KERNEL in cs_alloc_cmds()
 * add sanity check for CS_SET_WAKELINE ioctl
 * cleanup driver initialisation
 * rename driver to cmt-speech to be consistent with
   ssi-protocol driver
 * move cs-protocol.h to include/uapi/linux/hsi, since
   it describes a userspace API
 * replace hardcoded channels numbers with values provided
   via the HSI framework (e.g. coming from DT)

fa2d8ff4e3 openvswitch: Return vport module ref before destruction
Return module reference before invoking the respective vport
->destroy() function. This is needed as ovs_vport_del() is not
invoked inside an RCU read side critical section so the kfree
can occur immediately before returning to ovs_vport_del().

Returning the module reference before ->destroy() is safe because
the module unregistration is blocked on ovs_lock which we hold
while destroying the datapath.

816c7667ea KVM: s390: migrate vcpu interrupt state
This patch adds support to migrate vcpu interrupts. Two new vcpu ioctls
are added which get/set the complete status of pending interrupts in one
go. The ioctls are marked as available with the new capability
KVM_CAP_S390_IRQ_STATE.

We can not use a ONEREG, as the number of pending local interrupts is not
constant and depends on the number of CPUs.

To retrieve the interrupt state we add an ioctl KVM_S390_GET_IRQ_STATE.
Its input parameter is a pointer to a struct kvm_s390_irq_state which
has a buffer and length.  For all currently pending interrupts, we copy
a struct kvm_s390_irq into the buffer and pass it to userspace.

To store interrupt state into a buffer provided by userspace, we add an
ioctl KVM_S390_SET_IRQ_STATE. It passes a struct kvm_s390_irq_state into
the kernel and injects all interrupts contained in the buffer.
