acbf7c627f crypto: talitos - second prepare step for adding ahash algorithms
Used talitos_alg_template in talitos_crypto_alg
so that it will accommodate ahash algorithms.
Added some preparation code for ahash allocation and removal.
No actual algorithms yet.

d5e4aaefd9 crypto: talitos - prepare for adding ahash algorithms
No functional changes.
Use a union in talitos_alg_template for the crypto_alg
so that we can add a member later for ahash_alg.

0a625fd2ab crypto: n2 - Add Niagara2 crypto driver
Current deficiencies:

1) No HMAC hash support yet.

2) Although the algs are registered as ASYNC they always run
   synchronously.

bf06099db1 crypto: skcipher - Add ablkcipher_walk interfaces
These are akin to the blkcipher_walk helpers.

The main differences in the async variant are:

1) Only physical walking is supported.  We can't hold on to
   kmap mappings across the async operation to support virtual
   ablkcipher_walk operations anyways.

2) Bounce buffers used for async more need to be persistent and
   freed at a later point in time when the async op completes.
   Therefore we maintain a list of writeback buffers and require
   that the ablkcipher_walk user call the 'complete' operation
   so we can copy the bounce buffers out to the real buffers and
   free up the bounce buffer chunks.

These interfaces will be used by the new Niagara2 crypto driver.

beb63da739 crypto: tcrypt - Add speed tests for async hashing
These are invoked in the 'mode' range of 400 to 499.

The cost of async vs. sync for the software algorithm implementations
varies.  It can be as low as 16 cycles but as much as a couple hundred.

d46a5ac7a7 padata: Use a timer to handle remaining objects in the reorder queues
padata_get_next needs to check whether the next object that
need serialization must be parallel processed by the local cpu.
This check was wrong implemented and returned always true,
so the try_again loop in padata_reorder was never taken. This
can lead to object leaks in some rare cases due to a race that
appears with the trylock in padata_reorder. The try_again loop
was not a good idea after all, because a cpu could take that
loop frequently, so we handle this with a timer instead.

This patch adds a timer to handle the race that appears with
the trylock. If cpu1 queues an object to the reorder queue while
cpu2 holds the pd->lock but left the while loop in padata_reorder
already, cpu2 can't care for this object and cpu1 exits because
it can't get the lock. Usually the next cpu that takes the lock
cares for this object too. We need the timer just if this object
was the last one that arrives to the reorder queues. The timer
function sends it out in this case.

check it at the start of the function but then we dereference it

always a valid pointer so I removed the check for null.

d615da093e staging: rtl8192su: add Support for Belkin F5D8053 v6
Please find attached a patch which adds the device ID for the Belkin
F5D8053 v6 to the rtl8192su driver. I've tested this in 2.6.34-rc3
(Ubuntu 9.10 amd64) and the network adapter is working flawlessly.

6536560cab Staging: dt3155: fix 50Hz configuration
According to the header file, dt3155_io.h, the 50/60 Hz configuration
is controlled by a bit in the I2C CSR2 register (bit 2).  The function
dt3155_init_isr actually reads the I2C CONFIG register into the global
I2C_CSR union variable then modifies the bit.  It then does a write
to the I2C CONFIG register with the global I2C_CONFIG union variable
which is not even set with a value anywhere in the driver.

My guess is 50Hz operation doesn't even work as-is.

Fix this by actually reading and writing the correct register with
the correct value.

d01f42a22e staging: usbip: Fix deadlock
When detaching a port from the client side (usbip --detach 0),
the event thread, on the server side, is going to deadlock.
The "eh" server thread is getting USBIP_EH_RESET event and calls:
  -> stub_device_reset() -> usb_reset_device()
the USB framework is then calling back _in the same "eh" thread_ :
  -> stub_disconnect() -> usbip_stop_eh() -> wait_for_completion()
the "eh" thread is being asleep forever, waiting for its own completion.
This patch checks if "eh" is the current thread, in usbip_stop_eh().

546d9e101e Staging: hv: name network device ethX rather than sethX
This patch makes the HyperV network device use the same naming scheme as
other virtual drivers (Xen, KVM). In an ideal world, userspace tools
would not care what the name is, but some users and applications do
care. Vyatta CLI is one of the tools that does depend on what the name
is.

The word oops comes to mind.  Original patch to merge the two work queues
in here (prior to Greg taking them into staging) changed the top half to
only use one of them and the bottom half to assume it was the other.

Currently causes a NULL pointer dereference if you enable any of the events
on an lis3l02dq. Just goes to show I need a few more regression tests.

A while ago I provided a patch that fixed device detection after device
removal (USB: sl811-hcd: Fix device disconnect).
Chris Brissette pointed out that the detection/removal counter method
to distinguish insert or remove my fail under certain conditions.
Latest SL811HS datasheet (Document 38-08008 Rev. *D) indicates that
bit 6 (SL11H_INTMASK_RD) of the Interrupt Status Register together with
bit 5 (SL11H_INTMASK_INSRMV) can be used to determine whether a device
has been inserted or removed.

due to asynchronous operations between ohci reset and ohci clocks shutdown.
This patch adds the reading of the control register between the reset of the

073900a28d USB: rename usb_buffer_alloc() and usb_buffer_free()
For more clearance what the functions actually do,

  usb_buffer_alloc() is renamed to usb_alloc_coherent()
  usb_buffer_free()  is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

[added compatibility macros so we can convert things easier - gregkh]
