ff2aeb1eb6 libata: convert to chained sg
libata used private sg iterator to handle padding sg.  Now that sg can
be chained, padding can be handled using standard sg ops.  Convert to
chained sg.

* s/qc->__sg/qc->sg/

* s/qc->pad_sgent/qc->extra_sg[]/.  Because chaining consumes one sg
  entry.  There need to be two extra sg entries.  The renaming is also
  for future addition of other extra sg entries.

* Padding setup is moved into ata_sg_setup_extra() which is organized
  in a way that future addition of other extra sg entries is easy.

* qc->orig_n_elem is unused and removed.

* qc->n_elem now contains the number of sg entries that LLDs should
  map.  qc->mapped_n_elem is added to carry the original number of
  mapped sgs for unmapping.

* The last sg of the original sg list is used to chain to extra sg
  list.  The original last sg is pointed to by qc->last_sg and the
  content is stored in qc->saved_last_sg.  It's restored during
  ata_sg_clean().

* All sg walking code has been updated.  Unnecessary assertions and
  checks for conditions the core layer already guarantees are removed.

642f149031 SG: Change sg_set_page() to take length and offset argument
Most drivers need to set length and offset as well, so may as well fold

Add sg_assign_page() for those two locations that only needed to set

3be6cbd73f [libata] kill ata_sg_is_last()
Short term, this works around a bug introduced by early sg-chaining
work.

Long term, removing this function eliminates a branch from a hot
path loop in each scatter/gather table build.  Also, as this code
demonstrates, we don't need to _track_ the end of the s/g list, as
long as we mark it in some way.  And doing so programatically is nice.
So its a useful cleanup, regardless of its short term effects.

Based conceptually on a quick patch by Jens Axboe.

9af5c9c97d libata-link: introduce ata_link
Introduce ata_link.  It abstracts PHY and sits between ata_port and
ata_device.  This new level of abstraction is necessary to support
SATA Port Multiplier, which basically adds a bunch of links (PHYs) to
a ATA host port.  Fields related to command execution, spd_limit and
EH are per-link and thus moved to ata_link.

This patch only defines the host link.  Multiple link handling will be
added later.  Also, a lot of ap->link derefences are added but many of
them will be removed as each part is converted to deal directly with
ata_link instead of ata_port.

This patch introduces no behavior change.

91a6902958 sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes
Well, first of all, I don't want to change so many files either.

What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.

In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(

Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)

Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.

Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

463fc696ed [SCSI] ipr: Use PCI-E reset API for new ipr adapter
Use a newly added PCI API to issue a PCI Fundamental reset
(warm reset) to a new ipr PCI-E adapter. Typically, the
ipr adapter uses the start BIST bit in config space to reset
an adapter. Issuing start BIST on this particular adapter
results in the PCI-E logic on the card losing sync, which
causes PCI-E errors, making the card unusable. The only reset
mechanism that exists on this hardware that does not have this
problem is PCI Fundamental reset (warm reset).

If an ipr adapter encounters an adapter error requiring an
adapter reset to recover from prior to driver load time, the
error will be ignored and recovery will not happen until the
initial timeout occurs waiting for the firmware to come ready,
which means a five minute timeout. Fix is to read the interrupt
register before clearing any of the interrupts at probe time.

24d6f2b50b [SCSI] ipr: Fix for oops following SATA request sense
This patch fixes a problem discovered on a system with some
bad SATA devices attached. If a command to a SATAPI device
times out and the device gets reset as part of error recovery,
its possible that ipr will set err_mask to indicate a device
error has occurred. If this happens, a request sense will get
issued by libata. Since scsi core thinks this scsi command is
now completed, because the device reset handler completed successfully,
scsi core will free the associated scsi command, which may
cause an oops when that request sense is completed later
by ipr. This patch ensures that any commands that get aborted
as a result of a device reset set err_mask appropriately so
that the request sense does not get sent.

20ce791a0e [SCSI] ipr: remove duplicate device id
This patch removes a duplicate device id from the IPR driver.  Based on
the ipr.h file, I'm not so sure this was intended to be a duplicate, and
if so, the .h file should be modified to use the proper sub-device id
instead.

This was pointed out to me by Kay Sievers <kay.sievers@suse.de>

e619e1a7cb [SCSI] ipr: PCI error recovery fix
Since the pci_block_user_cfg_access API was modified to track
block/unblocks, it was discovered that the ipr driver had a
path through its code (in PCI error recovery) which would unblock
when not previously blocked.

6d84c944fa [SCSI] ipr: Remove usage of pci driver data
Since ipr handles dynamic ids, it must handle driver_data
not being set, so remove the current usage of driver_data
so it can be used for other things in future patches.

ac719abab0 [SCSI] ipr: Reduce default error log size

prevent ipr from logging this additional data unless requested
