732eacc054 replace nested max/min macros with {max,min}3 macro
Use the new {max,min}3 macros to save some cycles and bytes on the stack.
This patch substitutes trivial nested macros with their counterpart.

bf6aede712 workqueue: add to_delayed_work() helper function
It is a fairly common operation to have a pointer to a work and to need a
pointer to the delayed work it is contained in.  In particular, all
delayed works which want to rearm themselves will have to do that.  So it
would seem fair to offer a helper function for this operation.

Yes, I was wrong with the patch: HIFN does not support 64-bit addresses
afaics.

Attached patch should not allow HIFN to be registered on 64-bit arch, so
crypto layer will fallback to the software algorithms.

37a8023ce5 [HIFN]: Improve PLL initialization
The current PLL initalization has a number of deficiencies:

- uses fixed multiplier of 8, which overclocks the chip when using a
  reference clock that operates at frequencies above 33MHz. According
  to a comment in the BSD source, this is true for the external clock
  on almost all every board.

- writes to a reserved bit

- doesn't follow the initialization procedure specified in chapter
  6.11.1 of the HIFN hardware users guide

- doesn't allow to use the PCI clock

This patch adds a module parameter to specify the reference clock
(pci or external) and its frequency and uses that to calculate the
optimum multiplier to reach the maximal speed. By default it uses
the external clock and assumes a speed of 66MHz, which effectively
halfs the frequency currently used.

332f8840f7 [CRYPTO] ablkcipher: Add distinct ABLKCIPHER type
Up until now we have ablkcipher algorithms have been identified as
type BLKCIPHER with the ASYNC bit set.  This is suboptimal because
ablkcipher refers to two things.  On the one hand it refers to the
top-level ablkcipher interface with requests.  On the other hand it
refers to and algorithm type underneath.

As it is you cannot request a synchronous block cipher algorithm
with the ablkcipher interface on top.  This is a problem because
we want to be able to eventually phase out the blkcipher top-level
interface.

This patch fixes this by making ABLKCIPHER its own type, just as
we have distinct types for HASH and DIGEST.  The type it associated
with the algorithm implementation only.

Which top-level interface is used for synchronous block ciphers is
then determined by the mask that's used.  If it's a specific mask
then the old blkcipher interface is given, otherwise we go with the
new ablkcipher interface.

stack expects it to be called from bottom halves.

It is done by simply scheduling callback invocation via dedicated

rescheduling performance (7 times slower than tasklet, for mode details
one can check this link:
http://tservice.net.ru/~s0mbre/blog/devel/other/2007_11_09.html).

f7d0561ea1 [CRYPTO] hifn_795x: HIFN 795x driver
This is a driver for HIFN 795x crypto accelerator chips.

It passed all tests for AES, DES and DES3_EDE except weak test for DES,
since hardware can not determine weak keys.
