* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/avr32-2.6:
  avr32: add ATAG_BOARDINFO
  don't check platform_get_irq's return value against zero
  avr32: init cannot ignore signals sent by force_sig_info()
  avr32: fix deadlock when reading clock list in debugfs
  avr32: Fix .size directive for cpu_enter_idle
  avr32: At32ap: pio fix typo "))" on gpio_irq_unmask prototype
  fix the wrong argument of the functions definition
