Linus Torvalds 6a5a3d6a4a SCSI misc on 20121012
This is an assorted set of stragglers into the merge window with driver
 updates for megaraid_sas, lpfc, bfi and mvumi. It also includes some fairly
 major fixes for virtio-scsi (scatterlist init), scsi_debug (off by one error),
 storvsc (use after free) and qla2xxx (potential deadlock).

Linus Torvalds ce40be7a82 Merge branch 'for-3.7/core' of git://git.kernel.dk/linux-block
Pull block IO update from Jens Axboe:
 "Core block IO bits for 3.7.  Not a huge round this time, it contains:

   - First series from Kent cleaning up and generalizing bio allocation
     and freeing.

   - WRITE_SAME support from Martin.

   - Mikulas patches to prevent O_DIRECT crashes when someone changes
     the block size of a device.

   - Make bio_split() work on data-less bio's (like trim/discards).

   - A few other minor fixups."

Fixed up silent semantic mis-merge as per Mikulas Patocka and Andrew
Morton.  It is due to the VM no longer using a prio-tree (see commit
6b2dbba8b6ac: "mm: replace vma prio_tree with an interval tree").

So make set_blocksize() use mapping_mapped() instead of open-coding the
internal VM knowledge that has changed.

Linus Torvalds 6432f21284 The big new feature added this time is supporting online resizing
using the meta_bg feature.  This allows us to resize file systems
 which are greater than 16TB.  In addition, the speed of online
 resizing has been improved in general.
 
 We also fix a number of races, some of which could lead to deadlocks,
 in ext4's Asynchronous I/O and online defrag support, thanks to good
 work by Dmitry Monakhov.
 
 There are also a large number of more minor bug fixes and cleanups
 from a number of other ext4 contributors, quite of few of which have
 submitted fixes for the first time.

Lance Ortiz d1efe3c324 ACPI: Add new sysfs interface to export device description
Add support to export the device description obtained from the ACPI _STR
method, if one exists for a device, to user-space via a sysfs interface.
This new interface provides a standard and platform neutral way for users
to obtain the description text stored in the ACPI _STR method.  If no
_STR method exists for the device, no sysfs 'description' file will be
created.  The 'description' file will be located in the /sys/devices/
directory using the device's path.

/sys/device/<bus>/<bridge path>/<device path>.../firmware_node/description

Example:

/sys/devices/pci0000:00/0000:00.07.0/0000:0e:00.0/firmware_node/description

It can also be located using the ACPI device path, for example:

/sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/PNP0A08:00/device:13/device:15/description
/sys/devices/LNXSYSTM:00/device:00/ACPI0004:00/ACPI0004:01/ACPI0007:02/description

Execute the 'cat' command on the 'description' file to obtain the
description string for that device.

This patch also includes documentation describing how the new sysfs
interface works

Changes from v1-v2 based on comments by Len Brown and Fengguang Wu
* Removed output "No Description" and leaving a NULL attribute if the
_STR method failed to evaluate.

* In acpi_device_remove_files() removed the redundent check of
dev->pnp.str_obj before calling free.  This check triggered a message
from smatch.

Pull networking changes from David Miller:

 2) Make SCTP more network namespace aware, from Eric Biederman.

 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

 4) Make openvswitch network namespace aware, from Pravin B Shelar.

 5) IPV6 NAT implementation, from Patrick McHardy.

 6) Server side support for TCP Fast Open, from Jerry Chu and others.

 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
    Borkmann.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

namespace changes.

Linus Torvalds d9a807461f USB merge for 3.7-rc1
Here is the big USB pull request for 3.7-rc1
 
 There are lots of gadget driver changes (including copying a bunch of
 files into the drivers/staging/ccg/ directory so that the other gadget
 drivers can be fixed up properly without breaking that driver), and we
 remove the old obsolete ub.c driver from the tree.  There are also the
 usual XHCI set of updates, and other various driver changes and updates.
 We also are trying hard to remove the old dbg() macro, but the final
 bits of that removal will be coming in through the networking tree

 "Here is the big USB pull request for 3.7-rc1

  There are lots of gadget driver changes (including copying a bunch of
  files into the drivers/staging/ccg/ directory so that the other gadget
  drivers can be fixed up properly without breaking that driver), and we
  remove the old obsolete ub.c driver from the tree.

  There are also the usual XHCI set of updates, and other various driver
  changes and updates.  We also are trying hard to remove the old dbg()
  macro, but the final bits of that removal will be coming in through
  the networking tree before we can delete it for good.

Fix up several annoying - but fairly mindless - conflicts due to the

Alex Elder 34b131849f rbd: add an rbd features field
Record the features values for each rbd image and each of its
snapshots.  This is really something that only becomes meaningful
for version 2 images, so this is just putting in place code
that will form common infrastructure.

It may be useful to expand the sysfs entries--and therefore the
information we maintain--for the image and for each snapshot.
But I'm going to hold off doing that until we start making
active use of the feature bits.

Alex Elder 02cdb02cea rbd: kill create_snap sysfs entry
Josh proposed the following change, and I don't think I could
explain it any better than he did:

    From: Josh Durgin <josh.durgin@inktank.com>
    Date: Tue, 24 Jul 2012 14:22:11 -0700
    To: ceph-devel <ceph-devel@vger.kernel.org>
    Message-ID: <500F1203.9050605@inktank.com>

    Right now the kernel still has one piece of rbd management
    duplicated from the rbd command line tool: snapshot creation.
    There's nothing special about snapshot creation that makes it
    advantageous to do from the kernel, so I'd like to remove the
    create_snap sysfs interface.  That is,
	/sys/bus/rbd/devices/<id>/create_snap
    would be removed.

    Does anyone rely on the sysfs interface for creating rbd
    snapshots?  If so, how hard would it be to replace with:

	rbd snap create pool/image@snap

    Is there any benefit to the sysfs interface that I'm missing?

    Josh

This patch implements this proposal, removing the code that
implements the "snap_create" sysfs interface for rbd images.
As a result, quite a lot of other supporting code goes away.

Lan Tianyu ca9c9d0c92 usb : Add sysfs files to control port power.
This patch adds two sysfs files for each usb hub port to allow userspace
to control the port power policy.

For an upcoming Intel xHCI roothub, this will translate into ACPI calls
to completely power off or power on the port.  As a reminder, when these
ports are completely powered off, the USB host and device will see a
physical disconnect.  All future USB device connections will be lost,
and the device will not be able to signal a remote wakeup.

The control sysfs file can be written to with two options:
"on" - port power must be on.
"off" - port must be off.

The state sysfs file reports usb port's power state:
"on" - powered on
"off" - powered off
"error" - can't get power state

For now, let userspace dictate the port power off policy.  Future
patches may add an in-kernel policy.

Mark Brown f59c8f9fe6 regulator: core: Support bypass mode
Many regulators support a bypass mode where they simply switch their
input supply to the output. This is mainly used in low power retention
states where power consumption is extremely low so higher voltage or
less clean supplies can be used.

Support this by providing ops for the drivers and a consumer API which
allows the device to be put into bypass mode if all consumers enable it
and the machine enables permission for this.

This is not supported as a mode since the existing modes are rarely used
due to fuzzy definition and mostly redundant with modern hardware which is
able to respond promptly to load changes.

Andre Przywara 615b730071 acpi-cpufreq: Add support for disabling dynamic overclocking
One feature present in powernow-k8 that isn't present in acpi-cpufreq
is support for enabling or disabling AMD's core performance boost
technology. This patch adds support to acpi-cpufreq, but also
includes support for Intel's dynamic acceleration.

The original boost disabling sysfs file was per CPU, but acted
globally. Also the naming (cpb) was at least not intuitive.
So lets introduce a single file simply called "boost", which sits
once in /sys/devices/system/cpu/cpufreq.
This should be the only way of using this feature, so add
documentation about the rationale and the usage.

A following patch will re-introduce the cpb knob for compatibility
reasons on AMD CPUs.

Per-CPU boost switching is possible, but not trivial and is thus
postponed to a later patch series.

Mimi Zohar 07f6a79415 ima: add appraise action keywords and default rules
Unlike the IMA measurement policy, the appraise policy can not be dependent
on runtime process information, such as the task uid, as the 'security.ima'
xattr is written on file close and must be updated each time the file changes,
regardless of the current task uid.

This patch extends the policy language with 'fowner', defines an appraise
policy, which appraises all files owned by root, and defines 'ima_appraise_tcb',
a new boot command line option, to enable the appraise policy.

Changelog v3:
- separate the measure from the appraise rules in order to support measuring
  without appraising and appraising without measuring.
- change appraisal default for filesystems without xattr support to fail
- update default appraise policy for cgroups

Changelog v1:
- don't appraise RAMFS (Dmitry Kasatkin)
- merged rest of "ima: ima_must_appraise_or_measure API change" commit
  (Dmtiry Kasatkin)

  ima_must_appraise_or_measure() called ima_match_policy twice, which
  searched the policy for a matching rule.  Once for a matching measurement
  rule and subsequently for an appraisal rule. Searching the policy twice
  is unnecessary overhead, which could be noticeable with a large policy.

  The new version of ima_must_appraise_or_measure() does everything in a
  single iteration using a new version of ima_match_policy().  It returns
  IMA_MEASURE, IMA_APPRAISE mask.

  With the use of action mask only one efficient matching function
  is enough.  Removed other specific versions of matching functions.

Changelog:
- change 'owner' to 'fowner' to conform to the new LSM conditions posted by
  Roberto Sassu.
- fix calls to ima_log_string()

Tomas Hlavacek 6915c0e487 tty: uartclk value from serial_core exposed to sysfs
Added file /sys/devices/.../tty/ttySX/uartclk to allow reading
uartclk value in struct uart_port in serial_core via sysfs.

tty_register_device() has been generalized and refactored in order
to add support for setting drvdata and attribute_group to the device.

Maxim Mikityanskiy 0c7bbeb9f1 ideapad: add Lenovo IdeaPad Z570 support (part 3)
The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special
keys working, adds possibility to control fan like Windows does, controls
Touchpad Disabled LED, toggles touchpad state via keyboard controller and
corrects touchpad behavior on resume from suspend. It is new, modified
version of patch. Now it does not depend on psmouse and does not need patching
of input subsystem.

Zheng Liu 67a5da564f ext4: make the zero-out chunk size tunable
Currently in ext4 the length of zero-out chunk is set to 7 file system
blocks.  But if an inode has uninitailized extents from using
fallocate to preallocate space, and the workload issues many random
writes, this can cause a fragmented extent tree that will
unnecessarily grow the extent tree.

So create a new sysfs tunable, extent_max_zeroout_kb, which controls
the maximum size where blocks will be zeroed out instead of creating a
new uninitialized extent.  The default of this has been sent to 32kb.

AceLan Kao c0b91b6d52 asus-wmi: enable resume on lid open
According to the ASUS WMI spec., to enable resume on lid open should
use the device ID(0x00120032), but it doesn't work indeed.

After discussing with ASUS' BIOS engineer, they say wake on lid open
doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same
device ID with deep S3(0x00120031), and the deep S3(resume on lid open)
is disable by default.

Adding this option in asus wmi sysfs
   /sys/devices/platform/<platform>/lid_resume
so that userspace apps can enable/disable this feature by themselves.

 There are some patches in here outside of drivers/staging/, notibly the iio
 code (which is still stradeling the staging / not staging boundry), the pstore
 code, and the tracing code.  All of these have gotten ackes from the various
 subsystem maintainers to be included in this tree.  The pstore and tracing
 patches are related, and are coming here as they replace one of the android
 staging drivers.
 
 Otherwise, the normal staging mess.  Lots of cleanups and a few new drivers
 (some iio drivers, and the large csr wireless driver abomination.)
 
 Note, you will get a merge issue with the following files:
 	drivers/staging/comedi/drivers/s626.h
 	drivers/staging/gdm72xx/netlink_k.c
 both of which should be trivial for you to handle.
