2013-01-03Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2008-01-11[HIFN]: Improve PLL initializationPatrick McHardy
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.

2008-01-11[CRYPTO] ablkcipher: Add distinct ABLKCIPHER typeHerbert Xu
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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-01-11[CRYPTO] hifn: Schedule callback invocation to tasklet.Evgeniy Polyakov
This patch forces HIFN driver to invoke crypto request callbacks from tasklet (softirq context) instead of hardirq context, since network stack expects it to be called from bottom halves. It is done by simply scheduling callback invocation via dedicated tasklet. Workqueue solution was dropped because of tooo slow 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). Driver passed all AES and DES tests in tcryt.c module. Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
