cf7a44168d md: make sure read errors are auto-corrected during a 'check' resync in raid1
Whenever a read error is found, we should attempt to overwrite with correct
data to 'fix' it.

However when do a 'check' pass (which compares data blocks that are
successfully read, but doesn't normally overwrite) we don't do that.  We
should.

d7f3d291a0 md: expose the degraded status of an assembled array through sysfs
The 'degraded' attribute is useful to quickly determine if the array is
degraded, instead of parsing 'mdadm -D' output or relying on the other
techniques (number of working devices against number of defined devices,
etc.).  The md code already keeps track of this attribute, so it's useful to
export it.

2b12ab6d33 md: 'sync_action' in sysfs returns wrong value for readonly arrays
When an array is started read-only, MD_RECOVERY_NEEDED can be set but no
recovery will be running.  This causes 'sync_action' to report the wrong
value.

We could remove the test for MD_RECOVERY_NEEDED, but doing so would leave a
small gap after requesting a sync action, where 'sync_action' would still
report the old value.

So make sure that for a read-only array, 'sync_action' always returns 'idle'.

4d936ec1fd md: software Raid autodetect dev list not array
In current release kernels the md module (Software RAID) uses a static
array (dev_t[128]) to store partition/device info temporarily for
autostart.

I discovered this (and that the devices are added as disks/partitions are
discovered at boot) while I was debugging why only one of my MD arrays would
come up whole, while all the others were short a disk.

I eventually discovered that it was enumerating through all of 9 of my 11 hds
(2 had only 4 partitions apiece) while the other 9 have 15 partitions (I
wanted 64 per drive...).  The last partition of the 8th drive in my 9 drive
raid 5 sets wasn't added, thus making the final md array short both a parity
and data disk, and it was started later, elsewhere.

This patch replaces that static array with a list.

3e6c6f630a Delay creation of khcvd thread
This changes hvc_init() to be called only when someone actually uses the
hvc_console driver.  Dave Jones complained when profiling bootup.

hvc_console used to only be for Power aka pSeries: now lguest and Xen both
want it built-in in case the kernel is a guest under one of those, even
though usually it will be a native boot.

5f519d7281 tty: expose new methods needed for drivers to get termios right
This adds three new functions (or in one case to be more exact makes it
always available)

tty_termios_copy_hw

Copies all the hardware settings from one termios structure to the other.
This is intended for drivers that support little or no hardware setting

tty_termios_encode_baud_rate

Allows you to set the input and output baud rate in a termios structure.  A
driver is supposed to set the resulting baud rate from a request so most
will want to use this function to set the resulting input and output rates
to match the hardware values.  Internally it knows about keeping Bxxx
encoding when possible to maximise compatibility.

tty_encode_baud_rate

As above but for the tty's own current termios structure

I suspect this will initially need some tweaking as it gets enabled by
driver patches over the next few mm cycles so consider this lot -mm only
for the moment so it can stabilize and end up neat before it goes to base.

I've tried not to break any obscure architectures - if you get a speed you
can't represent the code will print warnings on non updated termios systems
but not break.

Once this is merged and seems sane I've got a growing pile of driver
updates to use it - notably for USB serial drivers.

44a2db43eb lk201: remove obsolete driver
Remove the old-fashioned lk201 driver under drivers/tc/ that used to be
used by the old dz.c and zs.c drivers, which is now orphan code referred to
from nowhere and does not build anymore.  A modern replacement is available
as drivers/input/keyboard/lkkbd.c.

There are no plans to do anything about this piece of code and it does not
fit anywhere anymore, so it is not just a matter of maintenance or the lack
of.  There are still some bits that might be added to the new lkkbd.c
driver based on the old code, and the embedded hardware documentation which
is otherwise quite hard to get hold of might be useful to keep too.  Both
of these can be done separately though.  RIP.

1a614f5051 cciss: fix error reporting for SG_IO
This fixes a problem with the way cciss was filling out the "errors" field
of the request structure upon completion of requests.  Previously, it just
put a 1 or a 0 in there and used the negation of this as the uptodate
parameter to one of the functions in the block layer, being a block device.
 For the SG_IO ioctl, this was not sufficient, and we noticed that, for
example, sg_turs from sg3_utils did not correctly detect problems due to
cciss having set rq->errors incorrectly.

7fdfd4065c NBD: allow hung network I/O to be cancelled
Allow NBD I/O to be cancelled when a network outage occurs.  Previously, I/O
would just hang, and if enough I/O was hung in nbd, the system (at least
user-level) would completely hang until a TCP timeout (default, 15 minutes)
occurred.

The patch introduces a new ioctl NBD_SET_TIMEOUT that allows a transmit
timeout value (in seconds) to be specified.  Any network send that exceeds the
timeout will be cancelled and the nbd connection will be shut down.  I've
tested with various timeout values and 6 seconds seems to be a good choice for
the timeout.  If the NBD_SET_TIMEOUT ioctl is not called, you get the old (I/O
hang) behavior.

4b86a87256 NBD: set uninitialized devices to size 0
This fixes errors with utilities (such as LVM's vgscan) that try to scan all
devices.  Previously this would generate read errors when uninitialized nbd
devices were scanned:

# vgscan
   Reading all physical volumes.  This may take a while...
   /dev/nbd0: read failed after 0 of 1024 at 0: Input/output error
   /dev/nbd0: read failed after 0 of 1024 at 509804544: Input/output error
   /dev/nbd0: read failed after 0 of 2048 at 0: Input/output error
   /dev/nbd1: read failed after 0 of 1024 at 509804544: Input/output error
   /dev/nbd1: read failed after 0 of 2048 at 0: Input/output error

 From now on, uninitialized nbd devices will have size zero, which
prevents these errors.

http://bugzilla.kernel.org/show_bug.cgi?id=7746

Git 759448f459 `Kernel utf-8 handling'
partly resolved it by adding conversion between diacritics and
unicode. The patch below goes further by just turning diacritics into
unicode, hence providing better future support. The kbd support can be
fetched from
http://bugzilla.kernel.org/attachment.cgi?id=12313

This was tested in all of latin1, latin9, latin2 and unicode with french
and czech dead keys.

Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR
and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR.

_input_.  No, we don't want to store the translation, as it is potentially
sparse and large.

2b571a066a pcmcia: CompactFlash driver for PA Semi Electra boards
Driver for the CompactFlash slot on the PA Semi Electra eval board. It's
a simple device sitting on localbus, with interrupts and detect/voltage
control over GPIO.

The driver is implemented as an of_platform driver, and adds localbus
as a bus being probed by the of_platform framework.

0cbc591bf8 nbd: change a parameter's type to remove a memcpy call
This memcpy looks so strange, in fact it's merely a pointer dereference, so I
change the parameter's type to refer it more directly, this could make the
memcpy not needed anymore.

In the function nbd_read_stat where nbd_find_request is only once called, the
parameter served should be transformed accordingly.

04fc8bbcf5 kill DECLARE_MUTEX_LOCKED
DECLARE_MUTEX_LOCKED was used for semaphores used as completions and we've
got rid of them.  Well, except for one in libusual that the maintainer
explicitly wants to keep as semaphore.  So convert that useage to an
explicit sema_init and kill of DECLARE_MUTEX_LOCKED so that new code is
reminded to use a completion.

eb1f293060 Driver for the Atmel on-chip SSC on AT32AP and AT91
The Synchronous Serial Controller (SSC) on Atmel microprocessors are
capable of tranceiving many frame based protocols, like I2S.  Tested on the
AT32AP7000/ATSTK1000.

This driver is used in the ALSA sound driver for the AT73C213 external DAC
on the ATSTK1000 development board for AVR32.  This sound driver will be
submitted soon.

Hardware documentation can be found in the AT32AP7000 data sheet, which can
be downloaded from
http://www.atmel.com/dyn/products/datasheets.asp?family_id=682

4ba9b9d0ba Slab API: remove useless ctor parameter and reorder parameters
Slab constructors currently have a flags parameter that is never used.  And
the order of the arguments is opposite to other slab functions.  The object
pointer is placed before the kmem_cache pointer.

Convert

        ctor(void *object, struct kmem_cache *s, unsigned long flags)

to

        ctor(struct kmem_cache *s, void *object)

throughout the kernel
