05177f178e pata_atiixp: Don't disable
A couple of distributions (Fedora, Ubuntu) were having weird problems with the
ATI IXP series PATA controllers being reported as simplex.  At the heart of
the problem is that both distros ignored the recommendations to load pata_acpi
and ata_generic *AFTER* specific host drivers.

The underlying cause however is that if you D3 and then D0 an ATI IXP it
helpfully throws away some configuration and won't let you rewrite it.

Add checks to ata_generic and pata_acpi to pin ATIIXP devices.  Possibly the
real answer here is to quirk them and pin them, but right now we can't do that
before they've been pcim_enable()'d by a driver.

I'm indebted to David Gero for this.  His bug report not only reported the
problem but identified the cause correctly and he had tested the right values
to prove what was going on

[If you backport this for 2.6.24 you will need to pull in the 2.6.25
removal of the bogus WARN_ON() in pcim_enagle]

b3f677e501 sata_inic162x: use IDMA for ATAPI commands
Use IDMA for ATAPI commands.  Write and some misc commands time out
when executed using ATAPI_PROT_DMA but ATAPI_PROT_PIO works fine.  As
PIO is driven by DMA too, it doesn't make any noticeable difference
for native SATA devices.  inic_check_atapi_dma() is implemented to
force PIO for those ATAPI commands.

After this change, sata_inic162x issues all commands using IDMA.

3ad400a92e sata_inic162x: use IDMA for ATA_PROT_DMA
The modified driver on initio site has enough clue on how to use IDMA.
Use IDMA for ATA_PROT_DMA.

* LBA48 now works as long as it uses DMA (LBA48 devices still aren't
  allowed as it can destroy data if PIO is used for any reason).

* No need to mask IRQs for read DMAs as IDMA_DONE is properly raised
  after transfer to memory is actually completed.  There will be some
  spurious interrupts but host_intr will handle it correctly and
  manipulating port IRQ mask interacts badly with the other port for
  some reason, so command type dependent port IRQ masking is not used
  anymore.

364fac0e56 sata_inic162x: update TF read handling
inic162x can't reliably read back TF or at least we don't know how to
do it yet.  The only values which seem reliable are status and error.
This patch updates access to TF.

* implement inic_tf_read() which reads the TF area in mmio area

* implement custom inic_qc_fill_rtf() which only returns true if
  status indicates device error.  it'll be returning bogus addresses
  for device errors but it'll be able to report why it failed at
  least.

* implement custom inic_check_ready() and use ata_wait_after_reset()
  instead of the SFF version.

* use inic_tf_read() for classification.

This is not perfect but it fixes hotplug detection failure and at
least makes the driver report 0's instead of random garbages while
reporting valid status and error for device errors.

4c299ca364 sata_mv NCQ-EH for FIS-based switching
Convert sata_mv's EH for FIS-based switching (FBS) over to the
sequence recommended by Marvell.  This enables us to catch/analyze
multiple failed links on a port-multiplier when using NCQ.

To do this, we clear the ERR_DEV bit in the EDMA Halt-Conditions register,
so that the EDMA engine doesn't self-disable on the first NCQ error.

Our EH code sets the MV_PP_FLAG_DELAYED_EH flag to prevent new commands
being queued while we await completion of all outstanding NCQ commands
on all links of the failed PM.

The SATA Test Control register tells us which links have failed,
so we must only wait for any other active links to finish up
before we stop the EDMA and run the .error_handler afterward.

The patch also includes skeleton code for handling of non-NCQ FBS operation.
This is more for documentation purposes right now, as that mode is not yet
enabled in sata_mv.

29d187bb1e sata_mv delayed eh handling
Introduce a new "delayed error handling" mechanism in sata_mv,
to enable us to eventually deal with multiple simultaneous NCQ
failures on a single host link when a PM is present.

This involves a port flag (MV_PP_FLAG_DELAYED_EH) to prevent new
commands being queued, and a pmp bitmap to indicate which pmp links
had NCQ errors.

The new mv_pmp_error_handler() uses those values to invoke
ata_eh_analyze_ncq_error() on each failed link, prior to freezing
the port and passing control to sata_pmp_error_handler().

This is based upon a strategy suggested by Tejun.

For now, we just implement the delayed mechanism.
The next patch in this series will add the multiple-NCQ EH code
to take advantage of it.

37b9046a3e sata_mv NCQ and SError fixes for mv_err_intr
Sigh.  Undo some earlier changes to mv_port_intr(),
so that we now read/clear SError again in all cases.

Arrange the top of the function to be as close as possible
to what we need for a later update (in this series) for ERR_DEV handling.

Fix things so that libata-eh can attempt a READ_LOG_EXT_10H
in response to a failed NCQ command, by just doing a local
mv_eh_freeze() rather than ata_port_freeze().

This will now fully handle NCQ errors much of the time,
but more fixes are needed for FBS/PMP, and for certain chip errata.

9b2c4e0bae sata_mv wait for empty+idle
When performing EH, it is recommended to wait for the EDMA engine
to empty out requests-in-progress before disabling EDMA.

Introduce code to poll the EDMA_STATUS register for idle/empty bits
before disabling EDMA.  For non-EH operation, this will normally exit
without delay, other than the register read.

A later series of patches may focus on eliminating this and various
other register reads (when possible) throughout the driver,
but for now we're focussing on solid reliablity.

78ab88f04f libata: improve post-reset device ready test
Some controllers (jmb and inic162x) use 0x77 and 0x7f to indicate that
the device isn't ready yet.  It looks like they use 0xff if device
presence is detected but connection isn't established.  0x77 or 0x7f
after connection is established and use the value from signature FIS
after receiving it.

This patch implements ata_check_ready(), which takes TF status value
and determines whether the port is ready or not considering the above
and other conditions, and use it in @check_ready() functions.  This is
safe as both 0x77 and 0x7f aren't valid ready status value even though
they have BSY bit cleared.

This fixes hot plug detection failures which can be triggered with
certain drives if they aren't already spun up when the data connector
is hot plugged.

Tested on sil, sil24, ahci (jmb/ich), piix and inic162x combined with
eight drives from all major vendors.

17aa7e0344 dev_name introduction fall out fix
Commit 06916639e2 ("driver-core: add
dev_name() to help transition away from using bus_id") added a static
inline dev_name() and used it in dev_printk.

Unfortunately, drivers/edac/edac_core.h defines a macro called
dev_name().  Rename the latter.

7cfcd985d3 kgdb: 1000 loops for the single step test in kgdbts
The single step test is not terribly costly and it should be able to
pass at 1000 loops successfully in under 1 second.  A non-kgdb timing
regression was found using this test, but it did not occur frequently
because by default the test was only executed a single time.

This patch changes the default for the single step test to 1000
iterations and allows for individual configuration of the single step
test to further exercise the kgdb subsystem when needed.

7a1aa309f2 irda: fix !PNP support for drivers/net/irda/smsc-ircc2.c
x86.git testing found this build bug on v2.6.26-rc1:

  ERROR: "pnp_get_resource" [drivers/net/irda/smsc-ircc2.ko] undefined!
  make[1]: *** [__modpost] Error 1
  make: *** [modules] Error 2

the driver did not anticipate the case of !CONFIG_PNP which is rare but 
still possible. Instead of restricting the driver to PNP-only in the 
Kconfig space, add the (trivial) dummy struct pnp_driver - this is that 
other drivers use in the !PNP case too.

The driver itself can in theory be initialized on !PNP too in certain 
cases, via smsc_ircc_legacy_probe().

Patch only minimally build tested, i dont have this hardware.
