It is no longer needed to set hwif->mmio flag to tell IDE layer to not
manage resources so cleanup host drivers that used hwif->mmio flag only
for this purpose.
Ditto for ide_legacy_init_one().

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /

Do explicit port setup instead of depending on init_ide_data().
This way hwif->io_ports[] and hwif->irq are always correctly set
regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI.

* Add 'const struct ide_port_info *d' argument to ide_device_add[_all]().
* Factor out generic ports init from ide_pci_setup_ports() to ide_init_port(),
move it to ide-probe.c and call it in in ide_device_add_all() instead of
ide_pci_setup_ports().
* Move ->mate setup to ide_device_add_all() from ide_port_init().
* Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable
->autotune currently.
* Setup hwif->chipset in ide_init_port() but iff pi->chipset is set
(to not override setup done by ide_hwif_configure()).

* cmd640.c: set IDE_HFLAG_ABUSE_* also for CONFIG_BLK_DEV_CMD640_ENHANCED=n.

setup to pmac_ide_setup_device().

Delete filenames/versions from comments.
I'm leaving decisions about adding DRV_VERSION defines and MODULE_VERSION()-s
to maintainers of the respective drivers.

* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
file for probing PCI host drivers registered with IDE core (special case
for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of
the ordering in which all IDE host drivers are probed when IDE is built-in
during link time.
* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).
* Move probing of ide-cris (cris arch specific) host driver before cmd640
(x86 arch specific).
* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
(h8300 arch specific).
* Add "probe_vlb" kernel parameter to cmd640 host driver and update
Documentation/ide.txt accordingly.
* Make IDE_ARM config option visible so it can also be disabled if needed.
* Remove bogus comment from ide.c while at it.
v2:
* Fix two issues spotted by Sergei:
- replace ENOMEM error value by ENOENT in ide-h8300 host driver
- fix MODULE_PARM_DESC() in cmd640 host driver

Stop abusing ide_lock lock (switch to a private locking).

* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags
and set them in ht6560, cmd640, cmd64x and sc1200 host drivers.
* Add set_pio_mode_abuse() for checking if host driver has a non-standard
->tuneproc() implementation and use it in do_special().
* Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find
the maximum PIO mode supported by the host), also add ide_set_max_pio()
wrapper for ide_set_pio() to use for auto-tuning. Convert users of
->tuneproc to use ide_set{_max}_pio() where possible. This leaves only
do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
a direct users of ->tuneproc.
* Remove no longer needed ide_get_best_pio_mode() calls and printk-s
reporting PIO mode selected from ->tuneproc implementations.
* Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const.
* Remove stale comment from ide_config_drive_speed().
