ps3fb: Update for firmware 2.10

As of PS3 firmware version 2.10, the GPU command buffer size must be at least 2
MiB large. Since we use only a small part of the GPU command buffer and don't
want to waste precious XDR memory, move the GPU command buffer back to the
start of the XDR memory reserved for ps3fb and let the unused part overlap with
the actual frame buffer.

The patch described by the following excerpt from ChangeLog-2.6.24-rc1
eventually causes a "irq X: nobody cared" error after a while:

    [SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONE

After this happens, the kernel disables the IRQ, causing the SCSI card
to stop working until the next reboot.  The problem is caused by the
interrupt handler returning IRQ_NONE instead of IRQ_HANDLED after
handling an interrupt-on-the-fly (INTF) condition.  The following patch
fixes the problem.

140b5e5911 libata: fix ATAPI draining
With ATAPI transfer chunk size properly programmed, libata PIO HSM
should be able to handle full spurious data chunks.  Also, it's a good
idea to suppress trailing data warning for misc ATAPI commands as
there can be many of them per command - for example, if the chunk size
is 16 and the drive tries to transfer 510 bytes, there can be 31
trailing data messages.

This patch makes the following updates to libata ATAPI PIO HSM
implementation.

* Make it drain full spurious chunks.

* Suppress trailing data warning message for misc commands.

* Put limit on how many bytes can be drained.

* If odd, round up consumed bytes and the number of bytes to be
  drained.  This gets the number of bytes to drain right for drivers
  which do 16bit PIO.

This patch is partial backport of improve-ATAPI-data-xfer patchset
pending for #upstream.

3264a8d8f9 libata-acpi: implement _GTF command filtering
Implement _GTF command filtering which can be controlled by
libata.acpi_filter kernel parameter.  Currently SETXFER and LOCK
commands are filtered.

libata configures transfer mode by itself and _GTF SETXFER commands
can potentially disrupt device configuration.  _GTM/_STM mechanism
can't handle hotplugging too well and when _GTF is executed,
controller is in PIO0 rather than the mode _STM configured.

Note that detecting SET MAX LOCK requires looking at the previous
command.  This adds a bit to code complexity.

0e8634bf8e libata-acpi: improve _GTF execution error handling and reporting
As _GTF commands can't transfer data, device error never signals
transfer error.  It indicates that the device vetoed the operation, so
it's meaningless to retry.

This patch makes libata-acpi to report and continue on device errors
when executing _GTF commands.  Also commands rejected by device don't
contribute to the number of _GTF commands executed.

While at it, update _GTF execution reporting such that all successful
commands are logged at KERN_DEBUG and rename taskfile_load_raw() to
ata_acpi_run_tf() for consistency.

398e07826b libata-acpi: implement dev->gtf_cache and evaluate _GTF right after _STM during resume
On certain implementations, _GTF evaluation depends on preceding _STM
and both can be pretty picky about the configuration.  Using _GTM
result cached during controller initialization satisfies the most
neurotic _STM implementation.  However, libata evaluates _GTF after
reset during device configuration and the hardware state can be
different from what _GTF expects and can cause evaluation failure.

This patch adds dev->gtf_cache and updates ata_dev_get_GTF() such that
it uses the cached value if available.  Cache is cleared with a call
to ata_acpi_clear_gtf().

Because for SATA ACPI nodes _GTF must be evaluated after _SDD which
can't be done till IDENTIFY is complete, _GTF caching from
ata_acpi_on_resume() is used only for IDE ACPI nodes.

c05e6ff035 libata-acpi: implement and use ata_acpi_init_gtm()
_GTM fetches currently configured transfer mode while _STM configures
controller according to _GTM parameter and prepares transfer mode
configuration TFs for _GTF.  In many cases _GTM and _STM
implementations are quite brittle and can't cope with configuration
changed by libata.

libata does not depend on ATA ACPI to configure devices.  The only
reason libata performs _GTM and _STM are to make _GTF evaluation
succeed and libata also doesn't care about how _GTF TFs configure
transfer mode.  It overrides that configuration anyway, so from
libata's POV, it doesn't matter what value is feeded to _STM as long
as evaluation succeeds for _STM and following _GTF.

This patch adds dev->__acpi_init_gtm and store initial _GTM values on
host initialization before modified by reset and mode configuration.
If the field is valid, ata_acpi_init_gtm() returns pointer to the
saved _GTM structure; otherwise, NULL.

This saved value is used for _STM during resume and peek at
BIOS/firmware programmed initial timing for later use.  The accessor
is there to make building w/o ACPI easy as dev->__acpi_init doesn't
exist if ACPI is not enabled.

On driver detach, the initial BIOS configuration is restored by
executing _STM with the initial _GTM values such that the next driver
can also use the initial BIOS configured values.

4e5200334e sata_mv: improve warnings about Highpoint RocketRAID 23xx cards
Improve the existing boot/load time warnings from sata_mv
for Highpoint RocketRAID 23xx cards, based on new knowledge
about where the BIOS likes to overwrite sectors with metadata.

Harmless to us, but very useful for end users.

Like ST380817AS / 3.42, ST3160023AS / 3.42 times out commands if NCQ
is used.  Blacklist it.  This is reported by Matheus Izvekov in the

f7fe7ad4bc libata: clear link->eh_info.serror from ata_std_postreset()
link->eh_info.serror is used to cache SError for controllers which
need it cleared from interrupt handler to clear IRQ.  It also should
be cleared after reset just like SError itself.

Make ata_std_postreset() clear link->eh_info.serror too and update
sata_sil such that it doesn't care about bookkeeping the value.

8cf32ac657 sata_sil: fix spurious IRQ handling
Interestingly, sata_sil raises spurious interrupts if it's coupled
with Sil SATA_PATA bridge.  Currently, sata_sil interrupt handler is
strict about spurious interrupts and freezes the port when it occurs.
This patch makes it more forgiving.

* On SATA PHY event interrupt, serror value is checked to see whether
  it really is PHYRDY CHG event.  If not, SATA PHY event interrupt is
  ignored.

* If ATA interrupt occurs while no command is in progress, it's
  cleared and ignored.

This fixes bugzilla bug 9505.

53e490936a iwlwifi: fix rf_kill state inconsistent during suspend and resume
The patch fixes the STATUS_RF_KILL_HW state is not cleared problem if the
device goes to suspend when the rf_kill switch is enabled. The bug causes
the driver always thinks the rf_kill switch is enabled (although it is
disabled) after resume.

1a8d122782 b43: Fix rfkill radio LED
This fixes Bug #9414

Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:

(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.

Once the above problems were fixed, additional difficulties were noted:

(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.

This patch fixes all of the above.

a5acc379e5 iwlwifi3945/4965: fix rate control algo reference leak
Fix rate control algo reference leak in case if network device has been
failed to register.  In this case special flag priv->mac80211_registered is
not set and the rate algo reference is not freeing on module unload.  That
leads to OOPs in further ieee80211 rate register/unregister procedure (by
any callee).

It should fix the bug #9470

9313794371 zd1211rw: Fix alignment problems
Shaddy Baddah found an alignment problem with zd1211rw driver at
2007-11-19. This patch fixes it, it is based on the patch proposed by
Herbert Xu. The alignment 4 has been the agreed value on the
linux-wireless mailing list.

Notify that the problem does only affect the old zd1211rw softmac
driver and not the zd1211rw-mac80211 driver. Daniel Drake has
already provided a patch for the replacement of the softmac
driver, which this patch will break.
