a813ce432f [PATCH] x86_64: Rename IOMMU option, fix help and mark option embedded.
- Rename the GART_IOMMU option to IOMMU to make clear it's not
   just for AMD
 - Rewrite the help text to better emphatise this fact
 - Make it an embedded option because too many people get it wrong.

To my astonishment I discovered the aacraid driver tests this
symbol directly. This looks quite broken to me - it's an internal
implementation detail of the PCI DMA API. Can the maintainer
please clarify what this test was intended to do?

03aba2f795 [SCSI] sd/scsi_lib simplify sd_rw_intr and scsi_io_completion
This patch simplifies "good_bytes" computation in sd_rw_intr().
sd: "good_bytes" computation is always done in terms of the resolution
of the device's medium, since after that it is the number of good bytes
we pass around and other layers/contexts (as opposed ot sd) can translate
that to their own resolution (block layer:512).  It also makes
scsi_io_completion() processing more straightforward, eliminating the
3rd argument to the function.

It also fixes a couple of bugs like not checking return value,
using "break" instead of "return;", etc.

I've been running with this patch for some time now on a
test (do-it-all) system.

f89d0a4e1d [SCSI] aic79xx: remove slave_destroy
Even with the latest fixes aic79xx still occasionally triggers the
BUG_ON in slave_destroy. Rather than trying to figure out the various
levels of interaction here I've decided to remove the callback altogether.

The primary reason for the slave_alloc / slave_destroy is to keep an
index of pointers to the sdevs associated with a given target.
However, by changing the arguments to the affected functions slightly
it's possible to avoid the use of that index entirely.
The only performance penalty we'll incur is in writing the
information for /proc/scsi/XXX, as we'll have to recurse over all
available sdevs to find the correct ones. But I doubt that reading
from /proc is in any way time-critical.

Disable controller interrupt before firing INIT cmd to FW.  Interrupt

75e1fcc0b1 [PATCH] vfs: add lock owner argument to flush operation
Pass the POSIX lock owner ID to the flush operation.

This is useful for filesystems which don't want to store any locking state
in inode->i_flock but want to handle locking/unlocking POSIX locks
internally.  FUSE is one such filesystem but I think it possible that some
network filesystems would need this also.

Also add a flag to indicate that a POSIX locking request was generated by
close(), so filesystems using the above feature won't send an extra locking
request in this case.

47005f255e [PATCH] libata: implement per-dev EH action mask eh_info->dev_action[]
Currently, the only per-dev EH action is REVALIDATE.  EH used to
exploit ehi->dev to do selective revalidation on a ATA bus.  However,
this is a bit hacky and makes it impossible to request selective
revalidation from outside of EH or add another per-dev EH action.

This patch adds per-dev EH action mask eh_info->dev_action[] and
update EH to use this field for REVALIDATE.  Note that per-dev actions
can still be specified at port-level and it has the same effect of
specifying the action for all devices on the port.

d7a80dad2f [PATCH] libata: convert several bmdma-style controllers to new EH, take #3
Convert sata_sis, svw, uli and vsc drivers to new EH.  All the drivers
used to specify ATA_FLAG_SATA_RESET to tell libata to use SATA
hardreset instead of SRST.  This patch makes all the converted drivers
use the standard bmdma error handler which uses both SRST and SATA
hardreset.

All the controllers should be able to perform SRST but still needs
verification.  If some of the controllers can't do SRST, it will be
very easy to spot as it will show up during boot probing.

c6387a48cf [SPARC]: Kill __irq_itoa().
This ugly hack was long overdue to die.

It was a way to print out Sparc interrupts in a more freindly format,
since IRQ numbers were arbitrary opaque 32-bit integers which vectored
into PIL levels.  These 32-bit integers were not necessarily in the
0-->NR_IRQS range, but the PILs they vectored to were.

The idea now is that we will increase NR_IRQS a little bit and use a
virtual<-->real IRQ number mapping scheme similar to PowerPC.

That makes this IRQ printing hack irrelevant, and furthermore only a
handful of drivers actually used __irq_itoa() making it even less
useful.

f0eb62b81d [PATCH] libata: add host_set->next for legacy two host_sets case, take #3
For a legacy ATA controller, libata registers two separate host sets.
There was no connection between the two hosts making it impossible to
traverse all ports related to the controller.  This patch adds
host_set->next which points to the second host_set and makes
ata_pci_remove_one() remove all associated host_sets.

* On device removal, all ports hanging off the device are properly
  detached.  Prior to this patch, ports on the first host_set weren't
  detached casuing oops on driver unloading.

* On device removal, both host_sets are properly freed

This will also be used by new power management code to suspend and
resume all ports of a controller.  host_set/port representation will
be improved to handle legacy controllers better and this host_set
linking will go away with it.

d4c85325a8 [PATCH] sata_sil: update device hotplug handling, take #2
SIEN on some 3112 controllers doesn't mask SATA IRQ properly.  IRQ
stays asserted even after SIEN is masked and IRQ is acked.  Also, even
while frozen, any SATA PHY event including hardreset raises SATA IRQ.
Clearing SError seems to be the only way to deassert SATA IRQ.

This patch makes sil_host_intr() clear SError on SATA IRQs and ignore
SATA IRQs reported while frozen so that hardreset doesn't trigger
hotplug event (which ends up hardresetting again).

In such cases, the port still gets re-frozen to minimize the danger of
screaming interrupts.  This results in one nil EH repeat on
controllers with broken SIEN but other than that does no harm.

5d5ff44fe6 [SCSI] fix up request buffer reference in various scsi drivers
Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their
queuecommand functions.  Those fields are internal storage for the
midlayer only and are used to restore the original payload after
request_buffer and request_bufflen have been overwritten for EH.  Using
the buffer and bufflen fields means they do very broken things in error

To handle this this patch returns a error upwards allowing xmitworker

let iscsi_write_space queue it back up if needed (this relies

Implement ATA part of hotplug.  To avoid probing broken devices over
and over again, disabled devices are not automatically detached.  They
are detached only if probing is requested for the device or the
associated port is offline.  Also, to avoid infinite probing loop,
Each device is probed only once per EH run.

As SATA PHY status is fragile, devices are detached only after it has
used up its recovery chances unless explicitly requested by LLDD or
user (LLDD may request direct detach if, for example, it supports cold
presence detection).

* some controllers can't wait for !BSY after hardreset (LLDD should

* (later) PM needs SRST w/ PMP==15 to operate after hardreset

conditions are met and do a follow-up softreset if necessary.

f5914a461e [PATCH] libata-hp-prep: add prereset() method and implement ata_std_prereset()
With hotplug, every reset might be a probing reset and thus something
similar to probe_init() is needed.  prereset() method is called before
a series of resets to a port and is the counterpart of postreset().
prereset() can tell EH to use different type of reset or skip reset by
modifying ehc->i.action.

This patch also implements ata_std_prereset().  Most controllers
should be able to use this function directly or with some wrapping.
After hotplug, different controllers need different actions to resume
the PHY and detect the newly attached device.  Controllers can be
categorized as follows.

* Controllers which can wait for the first D2H FIS after hotplug.
  Note that if the waiting is implemented by polling TF status, there
  needs to be a way to set BSY on PHY status change.  It can be
  implemented by hardware or with the help of the driver.

* Controllers which can wait for the first D2H FIS after sending
  COMRESET.  These controllers need to issue COMRESET to wait for the
  first FIS.  Note that the received D2H FIS could be the first D2H
  FIS after POR (power-on-reset) or D2H FIS in response to the
  COMRESET.  Some controllers use COMRESET as TF status
  synchronization point and clear TF automatically (sata_sil).

* Controllers which cannot wait for the first D2H FIS reliably.
  Blindly issuing SRST to spinning-up device often results in command
  issue failure or timeout, causing extended delay.  For these
  controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT
  (currently 8s) to give newly attached device time to spin up, then
  issues reset.  Note that failing to getting ready in ATA_SPINUP_WAIT
  is not critical.  libata will retry.  So, the timeout needs to be
  long enough to spin up most devices.

LLDDs can tell ata_std_prereset() which of above action is needed with
ATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags.  These flags
are PHY-specific property and will be moved to ata_link later.

While at it, this patch unifies function typedef's such that they all
have named arguments.

d7bb4cc757 [PATCH] libata-hp-prep: implement sata_phy_debounce()
With hotplug, PHY always needs to be debounced before a reset as any
reset might find new devices.  Extract PHY waiting code from
sata_phy_resume() and extend it to include SStatus debouncing.  Note
that sata_phy_debounce() is superset of what used to be done inside
sata_phy_resume().

Three default debounce timing parameters are defined to be used by
hot/boot plug.  As resume failure during probing will be properly
handled as errors, timeout doesn't have to be long as before.
probeinit() uses the same timeout to retain the original behavior.

max_id now means the maximum number of ids on the bus, which means it
is one greater than the largest possible id number.

091686d3b5 [SCSI] Return -EINVAL when "id == max_id" in scsi_scan_host_selected()
The scsi_scan_host_selected() should return -EINVAL when the id is equal
to the max_id. Currently it uses ">" when comparing with max_id, and
hence leaves the border case when "id==max_id".
The channel and lun have values valid from 0 up to,
and including, max_channel or max_lun. But, the valid values for id
range from 0 to max_id-1. This patch fixes the problem.

a6b2c5d475 [PATCH] PATCH: libata. Add ->data_xfer method
We need to pass the device in order to do per device checks such as
32bit I/O enables. With the changes to include dev->ap we now don't have
to add parameters however just clean them up. Also add data_xfer methods
to the existing drivers except ata_piix (which is in the other block of
patches). If you reject the piix one just add a data_xfer to it...
