XFER_SW_DMA_0 mode should be excluded from the extended cycle
timing computations.[ This is just a documentation fix -- code inside the affected
'if' block already makes sure to accept only PIO modes. ]Noticed-by: Sergei Shtylyov

Use the current PIO mode value instead of the physical maximum one
to determine the fastest allowed PIO for shared PIO/DMA timings.Affected host drivers: amd74xx and via82cxxx.

Add support for the CompactFlash specific PIO modes 5/6 and MWDMA modes 3/4.
Since there were no PIO5 capable hard drives produced and one would also need
66 MHz IDE clock to actually get the difference WRT the address setup timings
programmed, I decided to simply replace the old non-standard PIO mode 5 timings
with the CFA specified ones.Signed-off-by: Sergei Shtylyov

* Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling
to ide_get_identity_ioctl().* Use temporary buffer in ide_get_identity_ioctl() instead
of accessing drive->id directly.* Add ide_id_to_hd_driveid() inline to convert raw id into
struct hd_driveid format (needed on big-endian).* Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(),
cleanup ide_fix_driveid() and switch ide to use use raw id.* Remove no longer needed drive->driveid.
This leaves us with 3 users of struct hd_driveid in tree:
- arch/um/drivers/ubd_kern.c
- drivers/block/xsysace.c
- drivers/usb/storage/isd200.cWhile at it:
* Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros.
There should be no functional changes caused by this patch.

Make drive->id an unnamed union so id can be accessed either by using
'u16 *id' or 'struct hd_driveid *driveid'. Then convert all existing
drive->id users accordingly (using 'u16 *id' when possible).This is an intermediate step to make ide 'struct hd_driveid'-free.
While at it:
- Add missing KERN_CONTs in it821x.c.
- Use ATA_ID_WORDS and ATA_ID_*_LEN defines.
- Remove unnecessary checks for drive->id.
- s/drive_table/table/ in ide_in_drive_list().
- Cleanup ide_config_drive_speed() a bit.
- s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave().

All ide_pio_cycle_time() users already select CONFIG_IDE_TIMINGS
so move the function from ide-lib.c to ide-timings.c.While at it:
- convert ide_pio_cycle_time() to use ide_timing_find_mode()
- cleanup ide_pio_cycle_time() a bit
There should be no functional changes caused by this patch.

* Don't include ide-timing.h in cs5535 and sis5513 host drivers
(they don't need it currently).* Convert ide-timing.h to ide-timings.c library and add CONFIG_IDE_TIMINGS
config option to be selected by host drivers using the library.While at it:
- fix ide_timing_find_mode() placement
v2:
* Add missing EXPORT_SYMBOLs. (Stephen Rothwell )There should be no functional changes caused by this patch.
