Guennadi Liakhovetski ac8fb3e862 tmio: add a platform flag to disable card write-protection detection
Write-protection status is not always available, e.g., micro-SD cards do not
have a write-protection switch at all. This patch adds a flag to let platforms
force tmio_mmc to consider the card writable.

Guennadi Liakhovetski 311f3ac768 mmc: add DMA support to tmio_mmc driver, when used on SuperH
SDHI controllers on SuperH, served by the tmio_mmc driver, can use slave DMA
for data transfer. This patch adds support for the dmaengine API to the
tmio_mmc driver.

Grant Likely 44504b2beb of: change of_match_device to work with struct device
The of_node pointer is now stored directly in struct device, so
of_match_device() should work with any device, not just struct of_device.

This patch changes the interface to of_match_device() to accept a
struct device instead of struct of_device.

Grant Likely 4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

Grant Likely 597b9d1e44 drivercore: Add of_match_table to the common device drivers
OF-style matching can be available to any device, on any type of bus.
This patch allows any driver to provide an OF match table when CONFIG_OF
is enabled so that drivers can be bound against devices described in
the device tree.

Removed check to prevent hotplug of display devices within pciehp.
Originally this was thought to have been required within the PCI
Hotplug specification for some legacy devices.  However there is
no such requirement in the most recent revision. The check prevents
hotplug of not only display devices but also computational GPUs
which require serviceability.

Felix Radensky 3322340a9d PCI: Allow manual resource allocation for PCI hotplug bridges
At the moment only PCI-E briges can be flagged as hotplug, thus
allowing manual resource preallocation via pci=hpmemsize=nnM and
pci=hpiosize=nnM kernel parameters. Some PCI hotplug bridges, e.g.
PLX 6254 can also benefit from this functionalily, as kernel fails
to properly allocate their resources when hotplug device is added
and PCI bus is rescanned.

This patch adds header quirk for PLX 6254 that marks this bridge
as hotplug. Other PCI bridges with similar problems can use it
as well.

Arnaud Patard 3804a89bfb RTC: rtc-cmos: Fix binary mode support
As a follow-up to the thread about RTC support for some Loongson 2E/2F
boards, this patch tries to address the "REVISIT"/"FIXME" comments about
rtc binary mode handling and allow rtc to work with rtc in binary mode.
I've also raised the message about 24-h mode not supported to warning
otherwise, one may end up with no rtc without any message in the kernel
log.

Tejun Heo c3e33e043f block,ide: simplify bdops->set_capacity() to ->unlock_native_capacity()
bdops->set_capacity() is unnecessarily generic.  All that's required
is a simple one way notification to lower level driver telling it to
try to unlock native capacity.  There's no reason to pass in target
capacity or return the new capacity.  The former is always the
inherent native capacity and the latter can be handled via the usual
device resize / revalidation path.  In fact, the current API is always
used that way.

Replace ->set_capacity() with ->unlock_native_capacity() which take
only @disk and doesn't return anything.  IDE which is the only current
user of the API is converted accordingly.

The removal of the 'waitqueue_active()' test in commit d7d05548a6

by David when he back-merged the main git tree into the networking tree
in commit 278554bd65 ("Merge branch 'master' of master.kernel.org:...").

There was a content conflict due to 'sock->sk->sk_sleep' being changed
into 'sk_sleep(sock->sk)' in the networking tree, but David didn't pick
up the iscsi change from the main tree.

Chase Douglas 7c4fda1aa1 i2c-nforce2: Remove redundant error messages on ACPI conflict
The ACPI subsystem strictly checks for resource conflicts. When there's
a conflict, it outputs a warning message with all the details needed to
properly diagnose the underlying issue. However, the i2c-nforce2 driver
also prints its own message. Not only is the message redundant, it is at
the KERN_ERR level, which overrides some bootsplash screens for no good
reason. This change removes the two lines that print out the error
messages.

Marek Szyprowski b868078487 i2c-gpio: Move initialization code to subsys_initcall()
GPIO driven I2C bus can be used for controlling the PMIC chip. The
example of such configuration is Samsung Aquila board.

This patch moves initialization code to subsys_initcall() to ensure
that the i2c bus is available early so the regulators can be quickly
probed and available for other devices on their probe() call.

Such solution has been proposed by Mark Brown to fix the problem of
the regulators not beeing available on the peripheral device probe():

Jean Delvare 7aeb96642f at24: Fall back to byte or word reads if needed
Increase the portability of the at24 driver by letting it read from
EEPROM chips connected to cheap SMBus controllers that support neither
raw I2C messages nor even I2C block reads. All SMBus controllers
should support either word reads or byte reads, so read support
becomes universal, much like with the legacy "eeprom" driver.

Obviously, this only works with EEPROM chips up to AT24C16, that use
8-bit offset addressing. 16-bit offset addressing is almost impossible
to support on SMBus controllers.

I did not add universal support for writes, as I had no immediate need
for this, but it could be added later if needed (with the same
performance issue as byte and word reads have, of course.)

Jean Delvare e0e8398c7a i2c-i801: All newer devices have all the optional features
Only the oldest devices lack some of the features supported by this
driver. List them explicitly, and default to all features enabled for
all other chips, including the ones added through sysfs. This will
make future driver maintenance easier.

In the unlikely event of a not yet supported device not implementing
all the features, one can always use the disable_features module
parameter to prevent the driver from attempting to use them.

Chris Wright de139a3393 pci: check caps from sysfs file open to read device dependent config space
The PCI config space bin_attr read handler has a hardcoded CAP_SYS_ADMIN
check to verify privileges before allowing a user to read device
dependent config space.  This is meant to protect from an unprivileged
user potentially locking up the box.

When assigning a PCI device directly to a guest with libvirt and KVM,
the sysfs config space file is chown'd to the unprivileged user that
the KVM guest will run as.  The guest needs to have full access to the
device's config space since it's responsible for driving the device.
However, despite being the owner of the sysfs file, the CAP_SYS_ADMIN
check will not allow read access beyond the config header.

With this patch we check privileges against the capabilities used when
openining the sysfs file.  The allows a privileged process to open the
file and hand it to an unprivileged process, and the unprivileged process
can still read all of the config space.

Eric W. Biederman 3ff195b011 sysfs: Implement sysfs tagged directory support.
The problem.  When implementing a network namespace I need to be able
to have multiple network devices with the same name.  Currently this
is a problem for /sys/class/net/*, /sys/devices/virtual/net/*, and
potentially a few other directories of the form /sys/ ... /net/*.

What this patch does is to add an additional tag field to the
sysfs dirent structure.  For directories that should show different
contents depending on the context such as /sys/class/net/, and
/sys/devices/virtual/net/ this tag field is used to specify the
context in which those directories should be visible.  Effectively
this is the same as creating multiple distinct directories with
the same name but internally to sysfs the result is nicer.

I am calling the concept of a single directory that looks like multiple
directories all at the same path in the filesystem tagged directories.

For the networking namespace the set of directories whose contents I need
to filter with tags can depend on the presence or absence of hotplug
hardware or which modules are currently loaded.  Which means I need
a simple race free way to setup those directories as tagged.

To achieve a reace free design all tagged directories are created
and managed by sysfs itself.

Users of this interface:
- define a type in the sysfs_tag_type enumeration.
- call sysfs_register_ns_types with the type and it's operations
- sysfs_exit_ns when an individual tag is no longer valid

- Implement mount_ns() which returns the ns of the calling process
  so we can attach it to a sysfs superblock.
- Implement ktype.namespace() which returns the ns of a syfs kobject.

Everything else is left up to sysfs and the driver layer.

For the network namespace mount_ns and namespace() are essentially
one line functions, and look to remain that.

Tags are currently represented a const void * pointers as that is
both generic, prevides enough information for equality comparisons,
and is trivial to create for current users, as it is just the
existing namespace pointer.

The work needed in sysfs is more extensive.  At each directory
or symlink creating I need to check if the directory it is being
created in is a tagged directory and if so generate the appropriate
tag to place on the sysfs_dirent.  Likewise at each symlink or
directory removal I need to check if the sysfs directory it is
being removed from is a tagged directory and if so figure out
which tag goes along with the name I am deleting.

Currently only directories which hold kobjects, and
symlinks are supported.  There is not enough information
in the current file attribute interfaces to give us anything
to discriminate on which makes it useless, and there are
no potential users which makes it an uninteresting problem
to solve.

David Zeuthen c3473c6354 generate "change" uevent for loop device
Recent udev versions probe loop devices for filesystems meaning that
the /dev/disk hierarchy may contain useful entries such as

 $ ls -l /dev/disk/by-label/Fedora-12-x86_64-Live
 lrwxrwxrwx 1 root root 11 Mar 11 13:41 /dev/disk/by-label/Fedora-12-x86_64-Live -> ../../loop0

Unfortunately, no "change" uevent is generated when the loop device is
detached so the symlink persists. Additionally, no "change" uevent is
guaranteed to be generated when attaching an fd or changing capacity.
For example,  user space could open the loop device O_RDONLY (in fact,
recent util-linux-ng does this) so udev's OPTIONS+="watch" machinery may
not trigger the "change" uevent.

This patch ensures that the "change" uevent is generated in all of
these cases. As a result, the /dev/disk hierarchy works as expected
for loop devices.

Fix a problem in early versions of the FPGA IP.

In certain situations the IP reports that the FIFO is empty, but a byte is
still clocked out.  If a flush is done at that point the currently clocked
byte is canceled.

This causes incompatibilities with the upper layers when a port is closed,
it waits until the FIFO is empty and then closes the port.  During close
the FIFO is flushed -> the last byte is not sent properly.

Now the FIFO is only flushed if it is reported to be non-empty.  Which
makes the currently clocked out byte to finish.
