The more relaxed memory ordering od the __raw_{write,read}b broke things
on ppc in the recent rivafb cleanups.
[ Uglyness alert: only the 8-bit accesses are more strongly serialized.
The 16- and 32-bit ones have always been relaxed. Gaah. ]

The patch below fixes a problem with shutting down 802.3ad bonds on the 2.6
kernel. Taking the interface down or removing the module causes a stack
dump if spinlock debugging is enabled. This patch was generated from the
2.6.9 kernel.
This patch has been peer reviewed by our Linux software engineering team,
and the fix has been verified by our test labs.

This patch undoes a change that we believe will impact performance
adversely, by creating possibly too long a delay between servicing
completions. The comment pretty much explains it. We need to call both
cleanup routines each pass through the loop, this time we have a comment
explaining why.

The 'faulty' personality provides a layer over any block device in which
errors may be synthesised.
A variety of errors are possible including transient and persistent read
and write errors, and read errors that persist until the next write.
There error mode can be changed on a live array.
Accessing this personality requires mdadm 2.8.0 or later.

This patch fixes some of the drivers' fb_blank() implementation which got
the usage of the VESA_* constants incorrectly and converts them to use the
new FB_BLANK-* constants.
I'm not sure if what I did is correct for all drivers, so maintainers,
please review.
(Note: For most of the drivers, FB_BLANK_NORMAL is treated as
FB_BLANK_UNBLANK, but returns a nonzero so fbcon will do a soft_blank).

The VESA_* constants in fb.h used for power management of the display is
confusing to use. The constants seems to be meant for userspace, because
within the kernel (vt and fbdev), the constants have to be incremented by
1. Implementation of fb_blank() varies from driver to driver:
- if-else on blank/!blank
- switch case on hardcoded numbers
- switch case on the constants + 1
- switch -1, case on constants as is
- switch case on the constants as is (broken)
To make usage clearer, new constants are defined in fb.h:
FB_BLANK_UNBLANK = VESA_UNBLANKING = 0;
FB_BLANK_NORMAL = VESA_UNBLANKING + 1 = 1;
FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1 = 2;
FB_BLANK_HSYNC_SUSPEND = VESA_HSYNC_SUSPEND + 1 = 3;
FB_BLANK_POWERDOWN = VESA_POWERDOWN + 1 = 4;
Other changes:
- generic blanking code in fbcon.c (for drivers without an fb_blank hook)
which either sets the palette to all black, or clear the screen with
black.
- make fb_display an unexportable symbol

This is a cx88 driver update, changes:
* adapt to video-buf changes.
* add support for a new card.
* use the new video-buf-dvb module.
The dvb stuff doesn't build yet as it depends on some cutting-edge code
from the linuxtv cvs and is tagged as 'BROKEN' because of that.
The patch also removes all trailing whitespaces. I've a script to remove
them from my sources now, that should kill those no-op whitespace changes
in my patches after merging this initial cleanup.

This is one more interface fix for the video-buf.c module, the first
attempt on that wasn't that clever. Instead of passing the driver private
data through all function calls I've just made that an element of the
videobuf_queue struct which is passed around everythere _anyway_.
That removes some reduncancy, should be less error prone and gain me some
points on rusty's interface design scala ;)
It also fixes the tvtime crashes which where caused by overviewing one
place to fixup in the first attempt.

The following patch against 2.6.10-rc1 fixes the brain damage that was
found in the CPM2 uart driver. Previously, if 8250 was configured in, it
would use one set of numbers (which at the time didn't conflict with
anything, but have since been officially given to the Motorola i.MX driver)
and if 8250 wasn't in, it would masquerade as it. The following switches
us over to 204/46...49 (Which is still unclaimed).

profile_hook unconditionally takes a read lock on profile_lock if kernel
profiling is enabled. The lock protects the profile_hook notifier chain
from being written while it's being called. The routine profile_hook is
called in a very hot path though: every timer tick on every CPU. As you
can imagine, on a large system, this makes the cacheline containing
profile_lock pretty hot. Since oprofile was the only user of the
profile_hook, I removed the notifier chain altogether in favor of a simple
function pointer with the help of John Levon. This removes all of the
contention in the hot path since the variable is very seldom written and
simplifies things a little to boot.

You are absolutely correct. That notice slipped by us and should not be in

If someone with access to the mainline source could remove that for us we

A big update to the ColdFire FEC ethernet driver.
This has been in the works for a while (and thus tested for
a while too). Fundamentally through there is 3 important
changes:
. support 528x and 527x device families
. allow for multiple FEC devices to be present (for example 2 on the 5274/5)
. support the Kendein 8721 PHY

From: <tglx@linutronix.de>
To make spinlock/rwlock initialization consistent all over the kernel,
this patch converts explicit lock-initializers into spin_lock_init() and
rwlock_init() calls.
Currently, spinlocks and rwlocks are initialized in two different ways:
lock = SPIN_LOCK_UNLOCKED
spin_lock_init(&lock)
rwlock = RW_LOCK_UNLOCKED
rwlock_init(&rwlock)
this patch converts all explicit lock initializations to
spin_lock_init() or rwlock_init(). (Besides consistency this also helps
automatic lock validators and debugging code.)
The conversion was done with a script, it was verified manually and it
was reviewed, compiled and tested as far as possible on x86, ARM, PPC.
There is no runtime overhead or actual code change resulting out of this
patch, because spin_lock_init() and rwlock_init() are macros and are
thus equivalent to the explicit initialization method.
That's the second batch of the unifying patches.
