    Pull ARM updates from Russell King:
     "Included in this update:
    
       - perf updates from Will Deacon:
    
         The main changes are callchain stability fixes from Jean Pihet and
         event mapping and PMU name rework from Mark Rutland
    
         The latter is preparatory work for enabling some code re-use with
         arm64 in the future.
    
       - updates for nommu from Uwe Kleine-König:
    
         Two different fixes for the same problem making some ARM nommu
         configurations not boot since 3.6-rc1.  The problem is that
         user_addr_max returned the biggest available RAM address which
         makes some copy_from_user variants fail to read from XIP memory.
    
       - deprecate legacy OMAP DMA API, in preparation for it's removal.
    
         The popular drivers have been converted over, leaving a very small
         number of rarely used drivers, which hopefully can be converted
         during the next cycle with a bit more visibility (and hopefully
         people popping out of the woodwork to help test)
    
       - more tweaks for BE systems, particularly with the kernel image
         format.  In connection with this, I've cleaned up the way we
         generate the linker script for the decompressor.
    
       - removal of hard-coded assumptions of the kernel stack size, making
         everywhere depend on the value of THREAD_SIZE_ORDER.
    
       - MCPM updates from Nicolas Pitre.
    
       - Make it easier for proper CPU part number checks (which should
         always include the vendor field).
    
       - Assembly code optimisation - use the "bx" instruction when
         returning from a function on ARMv6+ rather than "mov pc, reg".
    
       - Save the last kernel misaligned fault location and report it via
         the procfs alignment file.
    
       - Clean up the way we create the initial stack frame, which is a
         repeated pattern in several different locations.
    
       - Support for 8-byte get_user(), needed for some DRM implementations.
    
       - mcs locking from Will Deacon.
    
       - Save and restore a few more Cortex-A9 registers (for errata
         workarounds)
    
       - Fix various aspects of the SWP emulation, and the ELF hwcap for the
         SWP instruction.
    
       - Update LPAE logic for pte_write and pmd_write to make it more
         correct.
    
       - Support for Broadcom Brahma15 CPU cores.
    
       - ARM assembly crypto updates from Ard Biesheuvel"
