* 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 <sfr@canb.auug.org.au>)
There should be no functional changes caused by this patch.

Also fix placement of comments in ide_timing_compute() while at it.
There should be no functional changes caused by this patch
(md5sum was verified to be the same before/after the patch).

* Check requested xfer mode against xfer modes instead of XFER_* masks
in ide_timing_compute() and cs5535.c::cs5535_set_speed().
* Remove XFER_[MODE,MWDMA,EPIO,PIO] masks.

Move struct ide_timing and IDE_TIMING_* defines to <linux/ide.h>
from drivers/ide/ide-timing.h.
While at it:
- use u8/u16 instead of short for struct ide_timing fields
- use enum for IDE_TIMING_*
There should be no functional changes caused by this patch.

Remove unused XFER_UDMA_SLOW from ide_timing[].
While at it:
- fix re-defining XFER_PIO_5 (no need to define it in ide-timing.h as
it is defined in <linux/ata.h> which is included by <linux/hdreg.h>)
- fix whitespace damage

Replace the FIT() macro with the kernel-provided clamp_val() macro.
FIT was always being called with a member of a struct ide_timing,
which are shorts, and constant constraints for the min and max.
Thus we can use clamp_val, rather than clamp_t.

Delete filenames/versions from comments.
I'm leaving decisions about adding DRV_VERSION defines and MODULE_VERSION()-s
to maintainers of the respective drivers.
While at it:
* Remove unused VERSION define from ide.c.
* Remove unused/stale DRV_VERSION define from au1xxx-ide.c.

* Add ->host_flags to ide_hwif_t to store ide_pci_device_t.host_flags,
assign it in setup-pci.c:ide_pci_setup_ports().
* Add IDE_HFLAG_PIO_NO_{BLACKLIST,DOWNGRADE} to ide_pci_device_t.host_flags
and teach ide_get_best_pio_mode() about them. Also remove needless
!drive->id check while at it (drive->id is always present).
* Convert amd74xx, via82cxxx and ide-timing.h to use ide_get_best_pio_mode()
and then remove no longer needed ide_find_best_pio_mode().
There should be no functionality changes caused by this patch.

* Check IORDY bit for PIO modes > 2.
* Some devices claim maximum PIO mode > 2 in id->tPIO, they were punished too
severly for this by being limited to PIO_SLOW. Limit them to PIO2 instead.
v2:
* Fix PIO number being returned incorrectly instead of PIO mode
(Noticed by Sergei).

The function ide_timing_compute() fails to *actually* take drive's
specified minimum PIO/DMA cycle times into account -- when doing this, it
calls ide_timing_merge() on the 'struct ide_timing' argument which contains
garbage at the moment, and then ultimately destroys the read cycle time by
quantizing the ide_timing[] entry, instead of copying from that entry to
the argument structure, and only then doing a merge/quantize.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
