Commit c8b3e02 renamed a variable, but missed one reference to it
inside a WARN_ON, causing it to incorrectly trigger.

The ADMA code path assumes that the 3 byte alignment fix doesn't cross
a page boundary. I'm not convinced this is worth supporting, but at
least print a warning in the off chance we'll actually see such a request.

Add tests that make sure the driver properly checks the blocks and
blksz fields and doesn't assume the sg list has a size that perfectly
matches the current request.

Add a couple of tests to make sure the host driver handles highmem
memory pages properly. Unfortunately there is no way to guarantee an
allocation below 4 GB in i386, so it might give you addresses that
are out of reach for the hardware (OTOH, so will any other highmem
allocation in the kernel).

Andrew Morton reported this s390 allmodconfig build failure:
kernel/built-in.o: In function `hrtick_start_fair':
sched.c:(.text+0x69c6): undefined reference to `__smp_call_function_single'
the reason is that s390 is not a generic-ipi SMP platform yet, while
the hrtick code relies on it. Fix the dependency.

Nvidia-based Apple Macbook Pros don't appear to handle backlight control
through the graphics card registers or ACPI, but instead trigger changes
via SMI calls. This driver registers a generic backlight device that
lets existing userspace deal with it. Code derived from Julien Blache's

Thecus N2100 has leds and a buzzer attached to a pca9532 controller. Attach

platform in n2100_leds.
With this patch, support for N2100 should be complete in mainline Linux.

NXP pca9532 is a LED dimmer/controller attached to i2c bus. It allows
attaching upto 16 leds which can either be on, off or dimmed and/or blinked
with the two PWM modulators available.
This driver is a "new-style" i2c driver that adheres to the driver model and
implements the led framework api. Since the leds connected to the driver are
platform specific, it is only useful when platform data is passed to the
driver to define what leds are connected to which pins.

We're calling request_irq() with a IRQs disabled.
No straightforward fix exists because we want to
enable these IRQs and setup state atomically before
getting into the IRQ handler the first time.
What happens now is that we mark the VIRQ to not be
automatically enabled by request_irq(). Then we
make explicit enable_irq() calls when we grab the
LDC channel.
This way we don't need to call request_irq() illegally
under the LDC channel lock any more.
Bump LDC version and release date.

Switch the ColdFire head start up code to be in the .text.head segment.
And make sure that segment is at the start of the final linked text
segment. Fixes the linker warnings about section use mis-matches:
WARNING: vmlinux.o(.text+0xa8): Section mismatch in reference from the variable _clear_bss to the function .init.text:start_kernel()
The function _clear_bss() references
the function __init start_kernel().
This is often because _clear_bss lacks a __init
annotation or the annotation of start_kernel is wrong.

95da310e66ee8090119596c70ca8432e57f9a97f ("usb_serial: API all change").
Delete it again. If it comes back, we'll need to drive a stake through
