Merge git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-2.6-irqflags

* git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-2.6-irqflags:
  Fix IRQ flag handling naming
  MIPS: Add missing #inclusions of <linux/irq.h>
  smc91x: Add missing #inclusion of <linux/irq.h>
  Drop a couple of unnecessary asm/system.h inclusions
  SH: Add missing consts to sys_execve() declaration
  Blackfin: Rename IRQ flags handling functions
  Blackfin: Add missing dep to asm/irqflags.h
  Blackfin: Rename DES PC2() symbol to avoid collision
  Blackfin: Split the BF532 BFIN_*_FIO_FLAG() functions to their own header
  Blackfin: Split PLL code from mach-specific cdef headers
