Bartlomiej Zolnierkiewicz 273b8385e5 ide: remove ide_init_default_irq() macro
* Use ide_default_irq() instead of ide_init_default_irq() in
  ide_generic host driver (so the correct IRQ is always set
  regardless of CONFIG_PCI / CONFIG_BLK_DEV_IDEPCI).

* Remove no longer needed ide_init_default_irq() macro.

Bartlomiej Zolnierkiewicz 9dfcd15a6d ide: remove ide_default_io_ctl() macro
It is always == '((base) + 0x206)' if CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=y
and it is not needed otherwise (arm, blackfin, parisc, ppc64, sh, sparc[64]).

Bartlomiej Zolnierkiewicz 0e33555fff ide: add CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS (take 2)
* Add CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS to drivers/ide/Kconfig and use
  it instead of defining IDE_ARCH_OBSOLETE_DEFAULTS in <arch/ide.h>.

v2:
* Define ide_default_irq() in ide-probe.c/ns87415.c if not already defined
  and drop defining ide_default_irq() for CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=n.

  [ Thanks to Stephen Rothwell and David Miller for noticing the problem. ]

Bartlomiej Zolnierkiewicz 1d850bd0b2 ppc: remove ppc_ide_md
* Add special cases for pplus and prep to ide_default_{irq,io_base}()
  (+ FIXMEs about the need to use IDE platform host driver instead).

* Remove no longer needed ppc_ide_md and struct ide_machdep_calls.

* Then remove <linux/ide.h> include from:
  - arch/powerpc/kernel/setup_32.c
  - arch/ppc/kernel/ppc_ksyms.c
  - arch/ppc/kernel/setup.c
  - arch/ppc/platforms/pplus.c
  - arch/ppc/platforms/prep_setup.c

There should be no functional changes caused by this patch.

Bartlomiej Zolnierkiewicz 4ee06b7e67 ide: remove stale ide.h "configuration options"
Remove stale ide.h "configuration options":

* INITIAL_MULT_COUNT - always defined to 0

* SUPPORT_SLOW_DATA_PORTS - unused

* OK_TO_RESET_CONTROLLER - always defined to 1

* DISABLE_IRQ_NOSYNC - always defined to 0

Leave SUPPORT_VLB_SYNC (defined to 0 for CRIS and FRV, otherwise to 1)
for now but disallow overriding it by <asm/ide.h>.

There should be no functionality changes caused by this patch.

Adrian Bunk e6b6e3ffb9 [POWERPC] Remove APUS support from arch/ppc
Current status of APUS:
- arch/powerpc/: removed in 2.6.23
- arch/ppc/: marked BROKEN since 2 years

This therefore removes the remaining parts of APUS support from
arch/ppc, include/asm-ppc, arch/powerpc and include/asm-powerpc.

Benjamin Herrenschmidt 68a64357d1 [POWERPC] Merge 32 and 64 bits asm-powerpc/io.h
powerpc: Merge 32 and 64 bits asm-powerpc/io.h

The rework on io.h done for the new hookable accessors made it easier,
so I just finished the work and merged 32 and 64 bits io.h for arch/powerpc.

arch/ppc still uses the old version in asm-ppc, there is just too much gunk
in there that I really can't be bothered trying to cleanup.

Benjamin Herrenschmidt 4cb3cee03d [POWERPC] Allow hooking of PCI MMIO & PIO accessors on 64 bits
This patch reworks the way iSeries hooks on PCI IO operations (both MMIO
and PIO) and provides a generic way for other platforms to do so (we
have need to do that for various other platforms).

While reworking the IO ops, I ended up doing some spring cleaning in
io.h and eeh.h which I might want to split into 2 or 3 patches (among
others, eeh.h had a lot of useless stuff in it).

A side effect is that EEH for PIO should work now (it used to pass IO
ports down to the eeh address check functions which is bogus).

Also, new are MMIO "repeat" ops, which other archs like ARM already had,
and that we have too now: readsb, readsw, readsl, writesb, writesw,
writesl.

In the long run, I might also make EEH use the hooks instead
of wrapping at the toplevel, which would make things even cleaner and
relegate EEH completely in platforms/iseries, but we have to measure the
performance impact there (though it's really only on MMIO reads)

Since I also need to hook on ioremap, I shuffled the functions a bit
there. I introduced ioremap_flags() to use by drivers who want to pass
explicit flags to ioremap (and it can be hooked). The old __ioremap() is
still there as a low level and cannot be hooked, thus drivers who use it
should migrate unless they know they want the low level version.

The patch "arch provides generic iomap missing accessors" (should be
number 4 in this series) is a pre-requisite to provide full iomap
API support with this patch.
