Limit cpufv input to acceptables values.
Add an available_cpufv file to show available
presets.
Change cpufv ouput format from %d to %#x, it won't
break compatibility with existing userspace tools, but
it provide a more human readable output.

If we leave the camera disabled by default, userspace programs (e.g.
Skype, Cheese) leave the user out in the cold saying that the machine
"has no camera." Therefore, it's better to enable camera by default and
let people who really don't want it just disable the thing.
To reduce power usage you should enable USB autosuspend:
echo -n auto > /sys/bus/usb/drivers/uvcvideo/*:*/../power/level

Some BIOS re-use the same processor bus id
in different scope:
\_SB.SCK0.CPU0
\_SB.SCK1.CPU0
But the (deprecated) /proc/acpi/ interface
assumes the bus-id's are unique, resulting in an OOPS
when the processor driver is loaded:
WARNING: at fs/proc/generic.c:590 proc_register+0x148/0x180()
Hardware name: Sunrise Ridge
proc_dir_entry 'processor/CPU0' already registered

Rename the processor device bus id. And the new bus id will be
generated as the following format:
CPU+ CPU ID
For example: If the cpu ID is 5, then the bus ID will be "CPU5".
If the CPU ID is 10, then the bus ID will be "CPUA".
Yes, this will change the directory names seen
in /proc/acpi/processor/* on some systems.
Before this patch, those directory names where
totally arbitrary strings based on the interal AML device strings.

A number of places in the audit system we send an op= followed by a string
that includes spaces. Somehow this works but it's just wrong. This patch
moves all of those that I could find to be quoted.
Example:
Change From: type=CONFIG_CHANGE msg=audit(1244666690.117:31): auid=0 ses=1
subj=unconfined_u:unconfined_r:auditctl_t:s0-s0:c0.c1023 op=remove rule
key="number2" list=4 res=0
Change To: type=CONFIG_CHANGE msg=audit(1244666690.117:31): auid=0 ses=1
subj=unconfined_u:unconfined_r:auditctl_t:s0-s0:c0.c1023 op="remove rule"

audit_get_nd() is only used by audit_watch and could be more cleanly
implemented by having the audit watch functions call it when needed rather
than making the generic audit rule parsing code deal with those objects.

In preparation for converting audit to use fsnotify instead of inotify we
seperate the inode watching code into it's own file. This is similar to
how the audit tree watching code is already seperated into audit_tree.c

audit_update_watch() runs all of the rules for a given watch and duplicates
them, attaches a new watch to them, and then when it finishes that process
and has called free on all of the old rules (ok maybe still inside the rcu
grace period) it proceeds to use the last element from list_for_each_entry_safe()
as if it were a krule rather than being the audit_watch which was anchoring
the list to output a message about audit rules changing.
This patch unfies the audit message from two different places into a helper
function and calls it from the correct location in audit_update_rules(). We
will now get an audit message about the config changing for each rule (with
each rules filterkey) rather than the previous garbage.

The audit execve record splitting code estimates the length of the message
generated. But it forgot to include the "" that wrap each string in its
estimation. This means that execve messages with lots of tiny (1-2 byte)
arguments could still cause records greater than 8k to be emitted. Simply
fix the estimate.

Sometimes both acpi video and i915 driver are compiled as modules.
And there exists the strict dependency between the two drivers.
The acpi video bus will be unloaded in course of unloading the i915 driver.
If we unload the acpi video driver, then the kernel oops will be triggered.
Add the reference count to avoid unloading the ACPI video bus twice.
The reference count should be checked before unregistering the acpi video bus.
If the reference count is already zero, it won't unregister it again.
And after the acpi video bus is already unregistered, the reference count
will be set to zero.
