Pull ARM updates from Russell King:
 "Changes included in this pull request:

   - revert pxa2xx-flash back to using ioremap_cached() and switch
     memremap() to use arch_memremap_wb()

   - remove pci=firmware command line argument handling

   - remove unnecessary arm_dma_set_mask() implementation, the generic
     implementation will do for ARM

   - removal of the ARM kallsyms "hack" to work around mode switching
     veneers and vectors located below PAGE_OFFSET

   - tidy up build system output a little

   - add L2 cache power management DT bindings

   - remove duplicated local_irq_disable() in reboot paths

   - handle AMBA primecell devices better at registration time with PM
     domains (needed for Samsung SoCs)

   - ARM specific preparation to support Keystone II kexec"
