Currently, there's no generic HW flush management support in kernel.
Only 7 filesystems have their own way to manage the barrier flag.
This patch adds MS_BARRIER in sb_flags and conditionnaly issues the flush
in generic_file_fsync.
That option would be enabled from userspace mount tool.

There is a memory leak in ping. Current group_info had been got in
ping_init_sock and group_info->usage increased.
But the usage hasn't decreased anywhere in ping.
This will make this group_info never freed and cause memory leak.

There is a memory leak in ping when call ping in dumpstate.
Current group_info had been got in ping_init_sock and group_info->usage

This will make group_info never freed and cause memory leak.

Thunderbolt config areas contain capability lists similar to those found
on pci devices. This patch introduces a tb_find_cap utility method to
search for capabilities.

Every thunderbolt device consists (logically) of a switch with multiple
ports. Every port contains up to four config regions (HOPS, PORT,
SWITCH, COUNTERS) which are used to configure the device.
The tb_regs.h file contains all known registers and capabilities from
these config regions.
Thunderbolt switches have a plug events capability. This patch adds the
tb_plug_events_active method and uses it to activate plug events during
switch allocation.

Add utility methods tb_port_state and tb_wait_for_port. Add
tb_scan_switch which recursively checks for downstream switches.

Thunderbolt devices are configured by reading/writing into their
configuration space (similar to pci). This is done by sending packets
through the NHI (native host interface) onto the control channel.
This patch handles the low level packet based protocol and exposes
higher level operations like
We reveive a plug event callback whenever a thunderbolt device is added
or removed. This patch fills in the tb_handle_hotplug method and starts
reacting to these events by adding/removing switches from the hierarchy.

This patch makes changes to the pcieport driver to support thunderbolt
suspend/resume on apple systems. We need to perform two different
actions during suspend and resume:
The whole controller has to be powered down before suspend. If this is
not done then the NHI device will be gone after resume
We use _noirq since we have to restore the pci tunnels before the pci
core wakes the tunneled devices.

This was already reported, please refer to
A thunderbolt path is a unidirectional channel between two thunderbolt
ports. Two such paths are needed to establish a pci tunnel.
This patch introduces struct tb_path as well as a set of tb_path_*
methods which are used do activate & deactive paths.

A pci downstream and pci upstream port can be connected through a
tunnel. To establish the tunnel we have to setup two unidirectional
paths between the two ports.
Right now we only support paths with two hops (i.e. no chaining) and at
most one pci device per thunderbolt device.

Thunderbolt hotplug is supposed to be handled by the firmware. But Apple
decided to implement thunderbolt at the operating system level. The
firmare only initializes thunderbolt devices that are present at boot
time. This driver enables hotplug of thunderbolt of non-chained
thunderbolt devices on
Hi
This is version 2 of my Thunderbolt driver for Apple hardware (see [1] for v1).
The short story is that Apple decided to implement hotplug support in a driver
instead of the firmware. The firmware will only initialize coldplugged devices.
Hotplugged devices do not work.
This series adds
Add struct tb which will contain our view of the thunderbolt bus. For
now it just contains a pointer to the control channel and a workqueue
for hotplug events.
Add thunderbolt_alloc_and_start() and thunderbolt_shutdown_and_free()
which are responsible for setup and teardown of struct tb.

When the stalled-cycles-frontend event is requested without the cycles
event:
$ perf stat -e stalled-cycles-frontend -- git s
## acme...ram/acme
Performance counter stats for 'git s':

The same information can be gleaned from ctxt->d and avoids having

While initializing emulation context structure, kvm memsets to 0 a
number of fields some of which are redundant since they get set
eventually in x86_decode_insn. Cleanup unnecessary initializations
and remove some fields.

Please pull the audit tree for v3.15. You will have merge conflicts.
I'll publish my branch "merge-test" where I attempted to resolve them
the way you will.
The main issue is an across tree change to syscall_get_arch(). I change
it from taking a task_struct and pt_regs to take a void.
