Bartlomiej Zolnierkiewicz 303f1a76ae [libata] pata_efar: add locking for parallel scanning
Add clearing of UDMA enable bit also for PIO modes and then add
extra locking for parallel scanning.

This is similar change as commit 60c3be3 for ata_piix host driver
and while pata_efar doesn't enable parallel scan yet the race could
probably also be triggered by requesting re-scanning of both ports
at the same time using SCSI sysfs interface.

Alan Cox 16ea0fc98d libata: Pass host flags into the pci helper
This allows parallel scan and the like to be set without having to stop
using the existing full helper functions. This patch merely adds the argument
and fixes up the callers. It doesn't undo the special cases already in the
tree or add any new parallel callers.

Christoph Egger cb6643e1c3 [libata] pata_marvell: CONFIG_AHCI is really CONFIG_SATA_AHCI
The marvell driver comtains a fallback to ahci for the sata ports
which is incorrectly checked as CONFIG_AHCI while the only AHCI config
item is actually called SATA_AHCI (which also sounds sensible
considering it's a fallback for the sata ports).

Fix it by adding custom ->sff_exec_command method for UDMA33 chipsets.

Bart Hartgers 02d1d6160f sata_via: Correctly setup PIO/DMA for pata slave on vt6421.
Before only the timings for master were set. Datasheet can be found
here: ftp://ftp.vtbridge.org/Docs/Storage/DS_VT6421A_100_CCPL.PDF
Surprisingly, a slave drive works without this patch. According to the
datasheet, the controller by default derives the DMA mode from the
Set Features command issued to a drive. Not sure about the PIO
timings, though. The real problem is that the timings for the master
effectively are the ones tuned for the slave. If these support
different UDMA-settings, there is trouble, especially when the slave
supports a higher UDMA than the master.

Anyhow, using the same mechanism for both master and slave seems like
a good idea.

Tejun Heo 27943620cb libata: implement spurious irq handling for SFF and apply it to piix
Traditional IDE interface sucks in that it doesn't have a reliable IRQ
pending bit, so if the controller raises IRQ while the driver is
expecting it not to, the IRQ won't be cleared and eventually the IRQ
line will be killed by interrupt subsystem.  Some controllers have
non-standard mechanism to indicate IRQ pending so that this condition
can be detected and worked around.

This patch adds an optional operation ->sff_irq_check() which will be
called for each port from the ata_sff_interrupt() if an unexpected
interrupt is received.  If the operation returns %true,
->sff_check_status() and ->sff_irq_clear() will be cleared for the
port.  Note that this doesn't mark the interrupt as handled so it
won't prevent IRQ subsystem from killing the IRQ if this mechanism
fails to clear the spurious IRQ.

This patch also implements ->sff_irq_check() for ata_piix.  Note that
this adds slight overhead to shared IRQ operation as IRQs which are
destined for other controllers will trigger extra register accesses to
check whether IDE interrupt is pending but this solves rare screaming
IRQ cases and for some curious reason also helps weird BIOS related
glitch on Samsung n130 as reported in bko#14314.

  http://bugzilla.kernel.org/show_bug.cgi?id=14314

* piix_base_ops dropped as suggested by Sergei.

* Spurious IRQ detection doesn't kick in anymore if polling qc is in
  progress.  This provides less protection but some controllers have
  possible data corruption issues if the wrong register is accessed
  while a command is in progress.

Yinghai Lu 9a928660c9 pci: don't reassign to ROM res if it is not going to be enabled
A ROM resource that doesn't fit should not cause us to try to re-assign
all the bus resources.  Nobody generally cares, and re-assigning is
going to just cause way more troubles than it tries to solve.
