[GIT PATCH] driver core fixes for your 2.6-git tree

[GIT PATCH] driver core fixes for your 2.6-git tree

[Greg KH]

Here are 6 patches for your 2.6-git tree.

They contain:
	- 4 documentation updates:
		- ja_JP/HOWTO update
		- stable_kernel_rules.txt update
		- document the taint flags properly
		- fix some function comments in drivers/base/sys.c that
		  were incorrect.
	- bugfix for the dynamic_printk command line option
	- bugfix for the sysdev code

All of these have been in the -next trees and the -mm releases for a
while now.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

The patches will be sent as a follow-on to this message to lkml for people
to see.

thanks,

greg k-h

[PATCH 1/6] Document kernel taint flags properly

[Greg Kroah-Hartman]

This fills in the documentation for all of the current kernel taint
flags, and fixes the number for TAINT_CRAP, which was incorrectly
described.

[PATCH 2/6] driver core: drivers/base/sys.c: update comments

[Greg Kroah-Hartman]

From: Qinghuang Feng <s3c24xx@gmail.com>

There are no functions named sys_device_shutdown or sys_device_suspend
in the kernel.
They should be fixed to sysdev_shutdown and sysdev_suspend respectively.

Always return the full size instead of the consumed
length of the string in sysdev_store_{ulong,int}

This avoids EINVAL errors in some echo versions.

[PATCH 6/6] Driver core: fix 'dynamic_debug' cmd line parameter

[Greg Kroah-Hartman]

From: Jason Baron <jbaron@redhat.com>

In testing 2.6.28-rc1, I found that passing 'dynamic_printk' on the command
line didn't activate the debug code. The problem is that dynamic_printk_setup()
(which activates the debugging) is being called before dynamic_printk_init() is
called (which initializes infrastructure). Fix this by setting setting the
state to 'DYNAMIC_ENABLED_ALL' in dynamic_printk_setup(), which will also
cause all subsequent modules to have debugging automatically started, which is
probably the behavior we want.
