Merge branch 'paul' (Fixups from Paul Gortmaker)
This merges some of the fixes from Paul Gortmaker for the header file cleanup fallout. Some of the patches are going through arch maintainer trees, and David Howells suggested another be done differently, but this at least fixes a few cases. * emailed from Paul Gortmaker <paul.gortmaker@windriver.com>: asm-generic: add linux/types.h to cmpxchg.h firewire: restore the device.h include in linux/firewire.h frv: fix warnings in mb93090-mb00/pci-dma.c about implicit EXPORT_SYMBOL parisc: fix missing cmpxchg file error from system.h split blackfin: fix cmpxchg build fails from system.h fallout avr32: fix build failures from mis-naming of atmel_nand.h ARM: mach-msm: fix compile fail from system.h fallout irq_work: fix compile failure on MIPS from system.h split
