8e82f8c34b memstick: fix MSProHG 8-bit interface mode support
- 8-bit interface mode never worked properly.  The only adapter I have
  which supports the 8b mode (the Jmicron) had some problems with its
  clock wiring and they discovered it only now.  We also discovered that
  ProHG media is more sensitive to the ordering of initialization
  commands.

- Make the driver fall back to highest supported mode instead of always
  falling back to serial.  The driver will attempt the switch to 8b mode
  for any new MSPro card, but not all of them support it.  Previously,
  these new cards ended up in serial mode, which is not the best idea
  (they work fine with 4b, after all).

- Edit some macros for better conformance to Sony documentation

3aa04f1b07 atmel_lcdfb: disable LCD and DMA engines when suspending
When suspending the system with atmel_lcdfb enabled, I sometimes see
this:

	atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10

Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.

There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.

Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.

8275d102f8 ia64: fix panic during `modprobe -r xpc'
If you are on ia64 and you modprobe xpc then modprobe -r xpc, you
immediately get a panic.  xpc depends on xp which depends on gru for a
symbol.  That symbol is only used when we are running on UV hardware.

Currently, the GRU driver detects we are not on UV hardware and does no
initializing.  It does not do the same check when unloading.  As a result,
the gru driver attempts to tear down stuff that was not setup.

This is a simple two-line workaround to get us through this release.  Once
2.6.28 is opened, we need to rework the symbols that xp is depending on
from gru so the gru driver can properly fail to load when hardware is not
available.

7e96445533 pxa2xx_spi: dma bugfixes
Fixes two DMA bugs in the pxa2xx_spi driver.  The first bug is in all
versions of this driver; the second was introduced in the 2.6.20 kernel,
and prevents using the driver with chips like m25p16 flash (which can
issue large DMA reads).

 1. Zero length transfers are permitted for use to insert timing,
    but pxa2xx_spi.c will fail if this is requested in DMA mode.
    Fixed by using programmed I/O (PIO) mode for such transfers.

 2. Transfers larger than 8191 are not permitted in DMA mode.  A
    test for length rejects all large transfers regardless of DMA
    or PIO mode.  Worked around by rejecting only large transfers
    with DMA mapped buffers, and forcing all other transfers
    larger than 8191 to use PIO mode.  A rate limited warning is
    issued for DMA transfers forced to PIO mode.

This patch should apply to all kernels back to and including 2.6.20;
it was test patched against 2.6.20.  An additional patch would be
required for older kernels, but those versions are very buggy anyway.

8423597d67 pxa2xx_spi: chipselect bugfixes
Fixes several chipselect bugs in the pxa2xx_spi driver.  These bugs are in
all versions of this driver and prevent using it with chips like m25p16
flash.

 1. The spi_transfer.cs_change flag is handled too early:
    before spi_transfer.delay_usecs applies, thus making the
    delay ineffective at holding chip select.

 2. spi_transfer.delay_usecs is ignored on the last transfer
    of a message (likewise not holding chipselect long enough).

 3. If spi_transfer.cs_change is set on the last transfer, the
    chip select is always disabled, instead of the intended
    meaning: optionally holding chip select enabled for the
    next message.

Those first three bugs were fixed with a relocation of delays
and chip select de-assertions.

 4. If a message has the cs_change flag set on the last transfer,
    and had the chip select stayed enabled as requested (see 3,
    above), it would not have been disabled if the next message is
    for a different chip.  Fixed by dropping chip select regardless
    of cs_change at end of a message, if there is no next message
    or if the next message is for a different chip.

This patch should apply to all kernels back to and including 2.6.20;
it was test patched against 2.6.20.  An additional patch would be
required for older kernels, but those versions are very buggy anyway.

Use TX control flag IEEE80211_TX_CTL_ASSIGN_SEQ as a request to update

62ff2ecf7a ide: Fix pointer arithmetic in hpt3xx driver code (3rd try)
git commit 74811f355f causes crash at
module load (or boot) time on my machine with a hpt374 controller.
The reason for this is that for initializing second controller which sets
(hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which
advances it by one byte instead of advancing it by sizeof(hpt_info) bytes.
Because of this, all initialization functions get corrupted data in info
variable which causes a crash at boot time.

This patch fixes that and makes my machine boot again.

The card itself is a HPT374 raid conroller: Here is the lspci -v output:

c91ebe4961 [S390] cio: handle ssch() return codes correctly.
ssch() has two classes of return codes:
- condition codes (0-3) which need to be translated to Linux
  error codes
- Linux error codes (-EIO on exceptions) which should be passed
  to the caller (instead of erronously being handled like
  condition code 3)

9c2676b61a libata-sff: kill spurious WARN_ON() in ata_hsm_move()
On HSM_ST_ERR, ata_hsm_move() triggers WARN_ON() if AC_ERR_DEV or
AC_ERR_HSM is not set.  PHY events may trigger HSM_ST_ERR with other
error codes and, with or without it, there just isn't much reason to
do WARN_ON() on it.  Even if error code is not set there, core EH
logic won't have any problem dealing with the error condition.

OSDL bz#11065 reports this problem.

2fd673ecf0 sata_nv: disable hardreset for generic
of them being unifying probing, hotplug and EH reset paths uniform.
Previously, broken hardreset could go unnoticed as it wasn't used
during probing but when something goes wrong or after hotplug the
problem will surface and bite hard.

OSDL bug 11195 reports that sata_nv generic flavor falls into this
category.  Hardreset itself succeeds but PHY stays offline after
hardreset.  I tried longer debounce timing but the result was the
same.

  http://bugzilla.kernel.org/show_bug.cgi?id=11195

So, it seems we'll have to drop hardreset from the generic flavor.

5b66c829bf ahci, pata_marvell: play nicely together
I've been chasing Jeff about this for months.  Jeff added the Marvell
device identifiers to the ahci driver without making the AHCI driver
handle the PATA port. This means a lot of users can't use current
kernels and in most distro cases can't even install.

This has been going on since March 2008 for the 6121 Marvell, and late 2007
for the 6145!!!

This was all pointed out at the time and repeatedly ignored. Bugs assigned
to Jeff about this are ignored also.

To quote Jeff in email

> "Just switch the order of 'ahci' and 'pata_marvell' in
> /etc/modprobe.conf, then use Fedora's tools regenerate the initrd.

> See?  It's not rocket science, and the current configuration can be
> easily made to work for Fedora users."

(Which isn't trivial, isn't end user, shouldn't be needed, and as it usually
breaks at install time is in fact impossible)

To quote Jeff in August 2007

> "   mv-ahci-pata
> Marvell 6121/6141 PATA support.  Needs fixing in the 'PATA controller
> command' area before it is usable, and can go upstream."

Only he add the ids anyway later and caused regressions, adding a further
id in March causing more regresions.

The actual fix for the moment is very simple. If the user has included
the pata_marvell driver let it drive the ports. If they've only selected
for SATA support give them the AHCI driver which will run the port a fraction
faster. Allow the user to control this decision via ahci.marvell_enable as
a module parameter so that distributions can ship 'it works' defaults and
smarter users (or config tools) can then flip it over it desired.
