* Don't ask to enable no longer existing config options ("Use DMA by default when available" and "Special UDMA Feature"). * PIIX host driver doesn't support Victory66 chipset. * "ide0=cmd640_vlb" -> "cmd640.probe_vlb" * "ide=doubler" -> "gayle.doubler" * Amiga IDE doubler support is a feature for gayle host driver not a separate host driver. * Remove Andre's mail.

2008-04-28siimage: coding style cleanup (take 2)Sergei Shtylyov
Fix 18 errors and several warnings given by checkpatch.pl: - use of C99 // comments; - trailing whitespace; - 'switch' and 'case' not at the same indentation level; - no space before the open parenthesis of the 'if' and 'switch' statements; - space between function name and open parenthesis (though I have introduced such warnins in some places since the code looks prettier with the spaces); - including <asm/io.h> instead of <linux/io.h>; - line over 80 characters. In addition to these changes, also do the following: - make the arrays in sil_set_pio_mode() 'static', and make the arrays in sil_set_dma_mode() 'static const'; - change the string of the 'if' statements into the 'switch' statement in sil_pata_udma_filter(); - drop the needless '==' operators from the 'if' statements where a condition is a mere bit test; - remove needless initializer for the 'tmp' variable in init_chipset_siimage(); - beautify groups of the variable initializers and assignment operators; - add new line after variable definitions; - remove new line between the comment and the statements it refers to; - remove needless curly braces and parentheses; - fix typos, capitalize acronyms, etc. in the comments...

v2: * Update ->{in,out}_data methods to take 'struct request *rq' argument (thanks to Stephen Rothwell for catching it). There should be no functional changes caused by this patch.

2008-04-28ide: merge ->atapi_*put_bytes and ->ata_*put_data methodsBartlomiej Zolnierkiewicz
* Merge ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods into new ->{in,out}put_data methods which take number of bytes to transfer as an argument and always do padding. While at it: * Use 'hwif' or 'drive->hwif' instead of 'HWIF(drive)'. There should be no functional changes caused by this patch (all users of ->ata_{in,out}put_data methods were using multiply-of-4 word counts).

2008-04-28falconide/q40ide: add ->atapi_*put_bytes and ->ata_*put_data methods (take 2)Bartlomiej Zolnierkiewicz
* Add ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods to falconide and q40ide host drivers (->ata_* methods are implemented on top of ->atapi_* methods so they also do byte-swapping now). * Cleanup atapi_{in,out}put_bytes(). v2: * Add 'struct request *rq' argument to ->ata_{in,out}put_data methods and don't byte-swap disk fs requests (we shouldn't un-swap fs requests because fs itself is stored byte-swapped on the disk) - this is how things were done before the patch (ideally device mapper should be used instead but it would break existing setups and would have some performance impact).
