* ide: remove ->dma_master field from ide_hwif_t (take 5)Bartlomiej Zolnierkiewicz2008-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | * Convert cmd64x, hpt366 and pdc202xx_old host drivers to use pci_resource_start(hwif->pci_dev, 4) instead of hwif->dma_master. * Remove no longer needed ->dma_master field from ide_hwif_t. v2: * Use the more readable 'hwif->dma_base - (hwif->channel * 8)' instead of pci_resource_start(hwif->pci_dev, 4). v3: * Use hwif->extra_base in hpt366/pdc20xx_old + some cosmetic fixups over v2 (suggested by Sergei). v4: * Correct offsets in hpt3xxn_set_clock(). v5: * Use hwif->extra_base in hpt366 for _real_ this time.

* ide-io: set REQ_FAILED when drive is deadAristeu Rozanski2008-01-25

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the impending addition of the givcipher type, both blkcipher and ablkcipher algorithms will use it to create givcipher objects. As such it no longer makes sense to split the system between ablkcipher and blkcipher.

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.

| * | [CRYPTO] ablkcipher: Add distinct ABLKCIPHER typeHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

This cleans up the kset and kobject and ktype relationship and architecture, making sense of things now, and good documenation and samples are provided for others to use. Also the attributes for kobjects are much easier to handle now. This cleaned up a LOT of code all through the kernel, making kobjects easier to use if you want to. - struct bus_type has been reworked to now handle the lifetime rules properly, as the kobject is properly dynamic. - struct driver has also been reworked, and now the lifetime issues are resolved. - the block subsystem has been converted to use struct device now, and not "raw" kobjects. This patch has been in the -mm tree for over a year now, and finally all the issues are worked out with it. Older distros now properly work with new kernels, and no userspace updates are needed at all. - nozomi driver is added. This has also been in -mm for a long time, and many people have asked for it to go in. It is now in good enough shape to do so. - lots of class_device conversions to use struct device instead.

If the initial reference is dropped, the object will be removed from sysfs if needed, if an "add" event was sent, "remove" will be send, and the allocated resources are released. This allows us to clean up some driver core usage as well as allowing us to do other such changes to the rest of the kernel.
