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
