Merge git://git.infradead.org/users/dwmw2/random-2.6

* git://git.infradead.org/users/dwmw2/random-2.6:
  Fix autoloading of MacBook Pro backlight driver.
  Automatic MODULE_ALIAS() for DMI match tables.
  Remove asm/a.out.h files for all architectures without a.out support.
  Introduce HAVE_AOUT symbol to remove hard-coded arch list for BINFMT_AOUT
  Remove redundant CONFIG_ARCH_SUPPORTS_AOUT
  S390: Update comments about why we don't use <asm-generic/statfs.h>
  SPARC: Use <asm-generic/statfs.h>
  PowerPC: Use <asm-generic/statfs.h>
  PARISC: Use <asm-generic/statfs.h>
  x86_64: Use <asm-generic/statfs.h>
  IA64: Use <asm-generic/statfs.h>
  ARM: Use <asm-generic/statfs.h>
  Make <asm-generic/statfs.h> suitable for 64-bit platforms.
  Define and use PCI_DEVICE_ID_MARVELL_88ALP01_CCIC for CAFÉ camera driver
  [MTD] [NAND] Define and use PCI_DEVICE_ID_MARVELL_88ALP01_NAND for CAFÉ
  Use PCI_DEVICE_ID_88ALP01 for CAFÉ chip, rather than PCI_DEVICE_ID_CAFE.
  EFS: Don't set f_fsid in statfs().
