Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu: (25 commits) m68knommu: fix broken setting of irq_chip and handler m68knommu: switch to using -mcpu= flags for ColdFire targets m68knommu: arch/m68knommu/Kconfig whitespace cleanup m68knommu: create optimal separate instruction and data cache for ColdFire m68knommu: support ColdFire caches that do copyback and write-through m68knommu: support version 2 ColdFire split cache m68knommu: make cache push code ColdFire generic m68knommu: clean up ColdFire cache control code m68knommu: move inclusion of ColdFire v4 cache registers m68knommu: merge bit definitions for version 3 ColdFire cache controller m68knommu: create bit definitions for the version 2 ColdFire cache controller m68knommu: remove empty __iounmap() it is no used m68knommu: remove kernel_map() code, it is not used m68knommu: remove do_page_fault(), it is not used m68knommu: use user stack pointer hardware on some ColdFire cores m68knommu: remove command line printing DEBUG m68knommu: remove fasthandler interrupt code m68knommu: move UART addressing to part specific includes m68knommu: fix clock rate value reported for ColdFire 54xx parts m68knommu: move ColdFire CPU names into their headers ...
