David S. Miller e01698aed0 ide cmd64x: Remove serialize setting.
This begins to fix regressions reported by Frans Pop on his Ultra-10.

There are still some funnies left that we are investigating.

Joao Ramos 5bfb151f1f ide: do not access ide_drive_t 'drive_data' field directly
Change ide_drive_t 'drive_data' field from 'unsigned int' type to 'void *'
type, allowing a wider range of values/types to be stored in this field.

Added 'ide_get_drivedata' and 'ide_set_drivedata' helpers to get and set
the 'drive_data' field.

Fixed all host drivers to maintain coherency with the change in the
'drive_data' field type.

Sergei Shtylyov 628df2f33d cmd64x: implement test_irq() method
Convert the driver's two dma_test_irq() methods into test_irq() methods. The
driver will now use the standard dma_test_irq() method implementation which
allows to remove 'cmd54x_dma_ops' and 'cmd648_dma_ops' that become identical
to 'sff_dma_ops'...

Sergei Shtylyov 30e5ffc368 cmd64x: implement clear_irq() method (take 2)
Convert the driver's two dma_end() methods into clear_irq() methods -- the
driver will now use the standard dma_end() method implementation, ide_dma_end().

Bartlomiej Zolnierkiewicz 88b4132e10 ide: set/clear drive->waiting_for_dma flag in the core code
Set/clear drive->waiting_for_dma flag in the core code
instead of in ->dma_setup and ->dma_end methods.

There should be no functional changes caused by this patch.

Bartlomiej Zolnierkiewicz 4453011f95 ide: destroy DMA mappings after ending DMA (v2)
Move ide_destroy_dmatable() call out from ->dma_end method to
{ide_pc,cdrom_newpc,ide_dma}_intr(), ide_dma_timeout_retry()
and sgiioc4_resetproc().

This causes minor/safe behavior changes w.r.t.:
* cmd64x.c::cmd64{8,x}_dma_end()
* cs5536.c::cs5536_dma_end()
* icside.c::icside_dma_end()
* it821x.c::it821x_dma_end()
* scc_pata.c::__scc_dma_end()
* sl82c105.c::sl82c105_dma_end()
* tx4939ide.c::tx4939ide_dma_end()

v2:
* Fix build for CONFIG_BLK_DEV_IDEDMA=n (reported by Randy Dunlap).

Bartlomiej Zolnierkiewicz 35c9b4daf4 ide: add ->dma_clear method and remove ->dma_timeout one
All custom ->dma_timeout implementations call the generic one thus it is
possible to have only an optional method for resetting DMA engine instead:

* Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105
  host drivers to use it.

* Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
 ->dma_timeout method.

* Make ide_dma_timeout() static.

There should be no functional changes caused by this patch.

Bartlomiej Zolnierkiewicz 22117d6eaa ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)
* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it.

* Add ->dma_timer_expiry method and use it to set hwif->expiry for
  ATA_PROT_DMA protocol in do_rw_taskfile().

* Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts.

* Move setting hwif->expiry from ide_execute_command() to its users and drop
  'expiry' argument.

* Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile().

* Remove ->dma_exec_cmd method and its implementations.

* Unexport ide_execute_command() and ide_dma_intr().

v2:
* Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap).

* Fix *dma_expiry naming (suggested by Sergei Shtylyov).

There should be no functional changes caused by this patch.

Bartlomiej Zolnierkiewicz 2ed0ef543a ide: fix ->init_chipset method to return 'int' value
* Return 0 instead of dev->irq in ->init_chipset implementations.

* Fix ->init_chipset method to return 'int' value instead of
  'unsigned int' one.

This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.

Sergei Shtylyov 592b531521 ide: move read_sff_dma_status() method to 'struct ide_dma_ops'
Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops'
to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only
required for SFF-8038i compatible IDE controller drivers (greatly cutting down
the number of initializers) as its only user (outside ide-dma-sff.c and such
drivers) appears to be ide_pci_check_simplex() which is only called for such
controllers...
