Instead of waiting a painful 5000ms, quirk_usb_disable_ehci() now does a
1000ms loop to wait for the BIOS to acknowledge the handoff.
The five second delay is really quite irritating to have to deal with
every boot up, and I very seriously doubt any non-broken bios takes more
than a second to do the actual handoff.

I have another Argosy USB storage device, which has the same problem
with the Argosy USB storage device already fixed in 2.6.27.7. But this
device has another product ID (840:84), so this patch adds a new entry
into unusual_devs to fix the mount problem.
I enclose here two patches: one against 2.6.27.8, and another against
the latest linus-git tree.

Use del_timer_sync() instead of del_timer() to make sure the timer won't
be running when we return from parport_wait_event(), because this would
crash due to destruction of timer_list.
This is untested and just based on a code review. Just think about the
following sequence of events:
- add_timer()
- down_interruptible() is interrupted by a signal.
- we enter the timer callback handler on another CPU.
- del_timer(), but the timer callback is still running.
- eturn from parport_wait_even, which destroys the automatic variable
"timer" while the callback is running on another CPU.

As a non-atomic value, it's only safe to look at entropy_count when the
pool lock is held, so we move the BUG_ON inside the lock for correctness.
Also remove the spurious comment. It's ok for entropy_count to
temporarily exceed POOLBITS so long as it's left in a consistent state
when the lock is released.
This is a more correct, simple, and idiomatic fix for the bug in
8b76f46a2d. I've left the reorderings introduced by that patch in place
as they're harmless, even though they don't properly deal with potential
atomicity issues.

The code to draw penguin logos always uses some properties of the main logo.
This is incorrect if additional logos (CONFIG_FB_LOGO_EXTRA=y) have different
types than the main logo, which causes corrupted logo images.
http://bugzilla.kernel.org/show_bug.cgi?id=12181
Hence skip additional logos that are not compatible with the main logo.
Technically, it's possible to draw multiple logos of different types on
truecolor displays, but this would complicate the (already quite
complicated) logo drawing code even more.

Provide a static debounce configuration mechanism for twl4030 GPIOs,
replacing the previous dynamic one. The single user of that mechanism was
for MMC card detect debouncing.
Boards can provide a bitmask saying which GPIOs to debounce (30 msec).
It's always enabled for pins with the MMC card-detect/VMMCx link active,
so most boards won't need to set the debounce mask.
This is a net code shrink, including runtime footprint.

rtc is clearly does not satisfy IS_ERR at the point where it is tested, so
I have changed the test to consider the just initialized rtc->rtc_dev.
The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@match exists@
expression x, E;
identifier fld;
position p1,p2;
@@
(
x = E;
|
x = E
|
x@p1->fld
... when != x = E
IS_ERR(x@p2)
... when any
)
@other_match exists@
expression match.x, E1, E2;
position match.p1,match.p2;
@@
x = E1
... when != x = E2
when != x@p1
x@p2
@ script:python depends on !other_match@
p1 << match.p1;
p2 << match.p2;
