Merge master.kernel.org:/home/rmk/linux-2.6-arm
* master.kernel.org:/home/rmk/linux-2.6-arm: [ARM] always allow dump_stack() to produce a backtrace [ARM] Fix non-page aligned boot time mappings [ARM] 4458/1: pxa: Fix CKEN usage and hence fix pxa suspend/resume [ARM] 4454/1: Use word accesses in Versatile PCI config reads
