Subject: [PATCH 00/10] avr32: Power Management support

This patch series adds support for "standby" and "mem" power modes on
the AT32AP700x CPUs.

I've also included a couple of fixes that should go in through other
trees in order to ease testing:
  #1 fixes an oops on suspend and shutdown. Picked from the linux-mtd
     list.
  #2 is a quick-n-dirty hack for a build problem when CONFIG_PM=y
  #7 is a quick-n-dirty suspend/resume implementation for macb which
     prevents it from waking up the system all the time.

This patch series is meant to apply to the avr32-arch branch of the
avr32 tree. It won't apply to 2.6.24, and even if you fix the
conflicts it won't work because of Kconfig changes. I've made the
necessary fixes and pushed it out to

git://git.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6.git atmel-2.6.24

and the result seems to work fine.

I haven't measured the time it takes to resume the system, but it
feels instantaneous, at least on the ATNGW100. The delay is more
noticeable on ATSTK1000 since it needs to power up the LCD panel
(the ltv350qv panel takes about 100 ms to power up).
