A common reason for device drivers to implement their own printk macros
is the lack of a printk prefix with the standard pr_xyz macros.
Introduce a pr_fmt() macro that is applied for every pr_xyz macro to the
format string.
The most common use of the pr_fmt macro would be to add the name of the
device driver to all pr_xyz messages in a source file.

Currently libata uses four methods to detect device presence.
1. PHY status if available.
2. TF register R/W test (only promotes presence, never demotes)
3. device signature after reset
4. IDENTIFY failure detection in SFF state machine
Combination of the above works well in most cases but recently there
have been a few reports where a phantom device causes unnecessary
delay during probe. In both cases, PHY status wasn't available. In
one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which
didn't qualify as #4. The other failed #2 but as it passed #3 and #4,
it still caused failure.
In both cases, phantom device reported diagnostic failure, so these
cases can be safely worked around by considering any !ATA_DRQ IDENTIFY
failure as NODEV_HINT if diagnostic failure is set.

With CONFIG_IRQSOFF_TRACER the trace_hardirqs_off() function includes
a call to __builtin_return_address(1). But we calltrace_hardirqs_off()
from early entry code. There we have just a single stack frame.
So this results in a kernel stack backchain walk that would walk beyond
the kernel stack. Following the NULL terminated backchain this results
in a lowcore read access.
To fix this we simply call trace_hardirqs_off_caller() and pass the
current instruction pointer.

This patch checks for volume, bass, treble, set mode and get mode

Instead of aborting the driver for load, this patch will allow it to

generic_checkmode() were called, via a callback, for some tvaudio chips.
There's just one callback code used on all those boards. So, it makes no
sense on keeping this as a callback.
Since there were some OOPS reported on tvaudio on kerneloops.org, this
patch removes this callback, adding the code at the only place were it
is called: inside chip_tread. A flag were added to indicate the need for
a kernel thread to set stereo mode on cards that needs it.
Using this more direct approach simplifies the code, making it more
robust against human errors.

dm_any_congested() just checks for the DMF_BLOCK_IO and has no
code to make sure that suspend waits for dm_any_congested() to

Without it, a race can occur with dm_table_put() attempting to

dm_any_congested() which is meant to be quick and return
immediately.
Two examples of problems:
1. Sleeping functions called from congested code, the caller
of which holds a spin lock.
2. An ABBA deadlock between pdflush and multipathd. The two locks
in contention are inode lock and kernel lock.

This fixes a deadlock appearing with some USB peripheral drivers
when running CDC ACM gadget code.
The newish (2.6.27) CDC ACM event notification mechanism sends
messages (IN to the host) which are short enough to fit in most
FIFOs. That means that with some peripheral controller drivers
(evidently not the ones used to verify the notification code!!)
the completion callback can be issued before queue() returns.
The deadlock would come because the completion callback and the
event-issuing code shared a spinlock. Fix is trivial: drop
that lock while queueing the message.
