[GIT PULL] AVR32 fixes

Hi Linus,

Please pull the 'for-linus' branch of

git://www.atmel.no/~hskinnemoen/linux/kernel/avr32.git for-linus

to receive the following updates.

The status of the various SL*B allocators on AVR32 is now as follows:
* SLAB works, but debugging is effectively disabled due to
ARCH_KMALLOC_MINALIGN.
* SLUB works, including debugging.
* SLOB seems to ignore ARCH_KMALLOC_MINALIGN, so it breaks DMA
(SPI in particular is affected by this.)

So since SLUB is currently the allocator that works best on AVR32, I've
enabled it by default for both ATSTK1002 and ATNGW100. Big thanks to
Christoph for fixing the ARCH_KMALLOC_MINALIGN vs. CONFIG_SLUB_DEBUG
issue.
