DMA can only be done from physical addresses; move the "virt_to_phys"
source/destination buffer address translation from the dbdma queueing

086fa5ff08 block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectors
The block layer calling convention is blk_queue_<limit name>.
blk_queue_max_sectors predates this practice, leading to some confusion.
Rename the function to appropriately reflect that its intended use is to
set max_hw_sectors.

Also introduce a temporary wrapper for backwards compability.  This can

d58b0c39e3 powerpc/macio: Rework hotplug media bay support
The hotplug mediabay has tendrils deep into drivers/ide code
which makes a libata port reather difficult. In addition it's
ugly and could be done better.

This reworks the interface between the mediabay and the rest
of the world so that:

   - Any macio_driver can now have a mediabay_event callback
which will be called when that driver sits on a mediabay and
it's been either plugged or unplugged. The device type is
passed as an argument. We can now move all the IDE cruft
into the IDE driver itself

   - A check_media_bay() function can be used to take a peek
at the type of device currently in the bay if any, a cleaner
variant of the previous function with the same name.

   - A pair of lock/unlock functions are exposed to allow the
IDE driver to block the hotplug callbacks during the initial
setup and probing of the bay in order to avoid nasty race
conditions.

   - The mediabay code no longer needs to spin on the status
register of the IDE interface when it detects an IDE device,
this is done just fine by the IDE code itself

Overall, less code, simpler, and allows for another driver
than our old drivers/ide based one.

5fa9167a1b pcmcia: rework the irq_req_t typedef
Most of the irq_req_t typedef'd struct can be re-worked quite
easily:

(1) IRQInfo2 was unused in any case, so drop it.

(2) IRQInfo1 was used write-only, so drop it.

(3) Instance (private data to be passed to the IRQ handler):
	Most PCMCIA drivers using pcmcia_request_irq() to actually
	register an IRQ handler set the "dev_id" to the same pointer
	as the "priv" pointer in struct pcmcia_device. Modify the two
	exceptions (ipwireless, ibmtr_cs) to also work this waym and
	set the IRQ handler's "dev_id" to p_dev->priv unconditionally.

(4) Handler is to be of type irq_handler_t.

(5) Handler != NULL already tells whether an IRQ handler is present.
	Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
	irq_req_t.Attributes.

28c1969ff8 ide: fix ioctl to pass requested transfer mode to ide_find_dma_mode instead of UDMA6
Currently, ide_cmd_ioctl when invoked for setting DMA transfer mode calls
ide_find_dma_mode with requested mode as XFER_UDMA_6. This prevents setting DMA
mode to any other value than the default (maximum) supported by the device (or
UDMA6, if supported) irrespective of the actual requested transfer mode and
returns error.

For example, setting mode to UDMA2 using hdparm, where UDMA4 is the default
transfer mode gives following error:
	# ./hdparm -d1 -Xudma2  /dev/hda
	 /dev/hda:hda: UDMA/66 mode selected
	 setting using_dma to 1 (on)
	 hda: UDMA/66 mode selected
	 setting xfermode to 66 (UltraDMA mode2)
	 HDIO_DRIVE_CMD(setxfermode) failed: Invalid argument
	 using_dma     =  1 (on)

This patch fixes the issue.

0fb18c4777 Revert "ide: try to use PIO Mode 0 during probe if possible"
This reverts commit 6029336426.

Ok, we really do need to revert this, even with Bart's sis5513.c
fix in there.

The problem is that several driver's ->set_pio_mode() method
depends upon the drive->media type being set properly.  Most
of them use this to enable prefetching, which can only be done
for disk media.

But the commit being reverted here calls ->set_pio_mode() before
it's setup.  Actually it considers everything disk because that
is the default media type set by ide_port_init_devices_data().

The set of drivers that depend upon the media type in their
->set_pio_method() are:

drivers/ide/alim15x3.c
drivers/ide/it8172.c
drivers/ide/it8213.c
drivers/ide/pdc202xx_old.c
drivers/ide/piix.c
drivers/ide/qd65xx.c
drivers/ide/sis5513.c
drivers/ide/slc90e66.c

And it is possible that we could fix this by guarding the prefetching
and other media dependent setting changes with a test on
IDE_PFLAG_PROBING in hwif->port_flags, that's simply too risky for
2.6.32-rcX and -stable.

9bd7496f5d ide: Serialize CMD643 and CMD646 to fix a hardware bug with SSD
CMD646 corrupts data on concurrent transfers on both channels when IDE SSD is
connected to one of the channels.

Setup that demonstrates this hardware bug: Ultra 5, onboard CMD646, rev 3.
/dev/hda is 8GB Seagate ST38410A in MWDMA2
/dev/hdd is 32GB SSD SiliconHardDisk in MWDMA2

- When reading /dev/hdd (for example with dd or fsck), reads from /dev/hda
  are corrupted, there are twiddled single bits 1->0 and some full 32-bit
  words corrupted, sometimes commands fail (which switches /dev/hda to
  PIO mode but the corruptions happen even in PIO).
- Reads from /dev/hdd don't seem to be corrupted (i.e. fsck passes fine).
- When I connected normal rotating harddisk to /dev/hdd, there was no
  corruption, so the corruption is something specific to SSD.
- I tried the same setup on a PCI card with CMD649 and saw no corruption.

This patch serializes the operation for CMD646 and 643 (I didn't test
CMD643 but it may have the same hw bug too because it's earlier design).
CMD649 is good. I don't know anything about CMD 648.

032665a26f Revert "Revert "ide: try to use PIO Mode 0 during probe if possible""
This reverts commit 24df31acaf.

The root cause of reported system hangs was (now fixed) sis5513 bug
and not "ide: try to use PIO Mode 0 during probe if possible" change
(commit 6029336426) so the revert was
incorrect (it simply replaced one regression with the other one).

e13ee546bb sis5513: fix PIO setup for ATAPI devices
Clear prefetch setting before potentially (re-)enabling it in
config_drive_art_rwp() so the transition of the device type on
the port from ATA to ATAPI (i.e. during warm-plug operation)
is handled correctly.

This is a really old bug (it probably goes back to very early
days of the driver) but it was only affecting warm-plug operation
until the recent "ide: try to use PIO Mode 0 during probe if
possible" change (commit 6029336426).

This reverts commit 6029336426.

Based upon a report by David Fries, wherein his system hangs
on bootup with sis5513 controller, right after the CDROM
is registered by ide-cd.c and the TOC is first read.
