Juergen Beisert 72330b0eee i.MX Framebuffer: Use readl/writel instead of direct pointer deref
This patch prepares the current i.MX1 framebuffer driver for usage in the
whole i.MX family. It switches to readl/writel for register accesses.
Also it moves the register definitions to the driver where they belong.

Sascha Hauer 74b114fe2c i.MX Framebuffer: remove gpio setup function
Remove the gpio mux setup function from i.MX framebuffer driver.
This function is platform specific and thus should be done by
the board setup. As there are currently no in-kernel users
of this driver we do not break anything.

Frederik Deweerdt 38aefbc585 ACPI toshiba: only register rfkill if bt is enabled
Part of the rfkill initialization was done whenever BT was on or not.  The
following patch checks for BT presence before registering the rfkill to
the input layer.  Some minor cleanups (> 80 char lines) were also added in
the process.

Ingo Brueckl 1c55f18717 console ASCII glyph 1:1 mapping
For the console, there is a 1:1 mapping of glyphs which cannot be found
in the current font.  This seems to be meant as a kind of 'emergency
fallback' for fonts without unicode mapping which otherwise would
display nothing readable on the screen.

At the moment it affects all chars for which no substitution character
is defined.  In particular this means that for all chars (>= 128) where
there is no iso88591-1/unicode character (e.g.  control character area)
you'll get the very strange 1:1 mapping of the (cp437) graphics card
glyphs.

I'm pretty sure that the 1:1 mapping should only affect strict ASCII
code characters, i.e.  chars < 128.

The patch limits the mapping as it probably was meant anyway.

Ingo Brueckl f75bc06e5d unicode table for cp437
There is a major bug in the cp437 to unicode translation table.  Char
0x7c is mapped to U+00a5 which is the Yen sign and wrong.  The right
mapping is U+00a6 (broken bar).

Furthermore, a mapping for U+00b4 (a widely used character) is missing
even though easily possible.

The patch fixes these, as well as it provides a few other useful
mappings.

The changes are as follows:

  0x0f (enhancement) enables a sort of currency symbol
  0x27 (bug) enables a sort of acute accent which is a widely used character
  0x44 (enhancement) enables a sort of icelandic capital letter eth
  0x7c (major bug) corrects mapping
  0xeb (enhancement) enables a sort of icelandic small letter eth
  0xee (enhancement) enables a sort of math 'element of'

The test-unit-ready portion of this patch was causing boots to fail on
my test machine (as in http://lkml.org/lkml/2008/12/5/161). With this

Mike Anderson found the same problem in the hp_hw_start_stop code,
and I applied the same solution in cdrom_read_cdda_bpc.

During a reset, releasing the swflag after it failed to be acquired would
cause a double unlock of the mutex.  Instead, test whether acquisition of

Kay Sievers cba767175b pktcdvd: remove broken dev_t export of class devices
The pktcdvd created class devices only export some sysfs files,
but have no char dev_t registered in the driver.

At class device creation time they copy the dev_t value of the
block device to the char device, wich will register a new char
device in the driver core and userspace, with a conflicting dev_t
value.

In many cases the class devices dev_t just points to a random
USB device. This fixes the sysfs "duplicate entry" errors.

Geoff Levand beaa4867ee fbcon: fix workqueue shutdown
Add a call to cancel_work_sync() in fbcon_exit() to cancel any pending
work in the fbcon workqueue.

The current implementation of fbcon_exit() sets the fbcon workqueue
function info->queue.func to NULL, but does not assure that there is no
work pending when it does so.  On occasion, depending on system timing,
there will still be pending work in the queue when fbcon_exit() is
called.  This results in a null pointer deference when run_workqueue()
tries to call the queue's work function.

Fixes errors on shutdown similar to these:

Hermann Lauer fbf0229e94 sungem: improve ethtool output with internal pcs and serdes
From: Hermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de>

Attached is a patch which improves the output of ethtool (see below)
to some sensefull values with a sungem fibre card which uses the
sungem interal pcs connected to a serdes chip. The seriallink case in
the driver is untouched.

Most values are hardcoded, because gigabit fibre autoneg is anyways
limited and the driver don't really support much at the moment with
that hardware.

Makes a Compaq 6735s boot reliably again.  It used to hang in the loop
on some boots.  Give the link one second to train, otherwise break out
of the loop and reset the previously set clock bits.

Nigel Cunningham ec9a13cdbf ieee1394: node manager causes up to ~3.25s delay in freezing tasks
The firewire nodemanager function "nodemgr_host_thread" contains a loop
that calls try_to_freeze near the top of the loop, but then delays for
up to 3.25 seconds (plus time to do work) before getting back to the top
of the loop. When starting a cycle post-boot, this doesn't seem to bite,
but it is causing a noticeable delay at boot time, when freezing
processes prior to starting to read the image.

The following patch adds invocation of try_to_freeze to the subloops
that are used in the body of this function. With these additions, the
time to freeze when starting to resume at boot time is virtually zero.
I'm no expert on firewire, and so don't know that we shouldn't check
the return value and jump back to the top of the loop or such like after
being frozen, but I submit it for your consideration.

Signed-off-by: Nigel Cunningham <nigel@tuxonice.net>

The delay until nodemgr freezes was up to 0.25s (plus time for node
probes) in Linux 2.6.27 and older and up to 3.25s (plus ~) since Linux
2.6.28-rc1, hence much more noticeable.

try_to_freeze() without any jump is correct.  The surrounding code in
the respective loops will catch whether another bus reset happens during
the freeze and handle it.

Benjamin Herrenschmidt f3179748a1 radeonfb: Disable new color expand acceleration unless explicitely enabled
This new color expansion acceleration for radeonfb appears to trigger
problems with X on VT switch and suspend/resume on some machines. It
might be a problem in the VT layer or in X, but I haven't quite found
it yet, so in the meantime, this disables the acceleration by default,
reverting to 2.6.27 state. It can be enabled using the "accel_cexp"
module parameter or fbdev argument.

David S. Miller 8c83f80b2d sungem: Make PCS PHY support partially work again.
As reported by Hermann Lauer, PCS PHY support in the sungem
driver simply doesn't work.

When the chip is reset due to open, or some other similar operation,
the PCS is reset too but we don't program it back into a running
state.  The result is no link when the device is brought up.

This partially rectifies the situation for the moment, by kicking
the PCS after a sungem chip reset so that it will renegotiate and
be re-enabled again.

The behavior is still a little bit dodgy as the added renegotiate
make the link take some time after bringing the interface up,
but this is a significant improvement in that things actually work
now :-)

Based almost entirely upon an initial patch by Hermann.

ata_piix: add borked Tecra M4 to broken suspend list

we possibly dereference null.

Check if they are null and avoid checks in that case.

Keith Packard b60678a75d drm/i915: Disable the GM965 MSI errata workaround.
Since applying the fix suggested by the errata (disabling MSI), we've had
issues with interrupts being stuck on despite IIR being 0 on GM965 hardware.
Most reporters of the issue have confirmed that turning MSI back on fixes
things, and given the difficulties experienced in getting reliable MSI working
on Linux, it's believable that the errata was about software issues and not
actual hardware issues.
