Merge branch 'acpi-assorted'

* acpi-assorted:
  ACPI: Add Toshiba NB100 to Vista _OSI blacklist
  ACPI / osl: remove an unneeded NULL check
  ACPI / platform: add ACPI ID for a Broadcom GPS chip
  ACPI: improve acpi_extract_package() utility
  ACPI / LPSS: fix UART Auto Flow Control
  ACPI / platform: Add ACPI IDs for Intel SST audio device
  x86 / ACPI: fix incorrect placement of __initdata tag
  ACPI / thermal: convert printk(LEVEL...) to pr_<lvl>
  ACPI / sysfs: make GPE sysfs attributes only accept correct values
  ACPI / EC: Convert all printk() calls to dynamic debug function
  ACPI / button: Using input_set_capability() to mark device's event capability
  ACPI / osl: implement acpi_os_sleep() with msleep()
