Merge git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6: (26 commits) sh: Convert sh to use read/update_persistent_clock sh: Move PMB debugfs entry initialization to later stage sh: Fix up flush_cache_vmap() on SMP. sh: fix up MMU reset with variable PMB mapping sizes. sh: establish PMB mappings for NUMA nodes. sh: check for existing mappings for bolted PMB entries. sh: fixed virt/phys mapping helpers for PMB. sh: make pmb iomapping configurable. sh: reworked dynamic PMB mapping. sh: Fix up cpumask_of_pcibus() for the NUMA build. serial: sh-sci: Tidy up build warnings. sh: Fix up ctrl_read/write stragglers in migor setup. serial: sh-sci: Add DMA support. dmaengine: shdma: extend .device_terminate_all() to record partial transfer sh: merge sh7722 and sh7724 DMA register definitions sh: activate runtime PM for dmaengine on sh7722 and sh7724 dmaengine: shdma: add runtime PM support. dmaengine: shdma: separate DMA headers. dmaengine: shdma: convert to platform device resources dmaengine: shdma: fix DMA error handling. ...
