      Pull ARM fixes from Russell King:
       "Three relatively small fixes for ARM:
      
         - Roger noticed that dma_max_pfn() was calculating the upper limit
           wrongly, by adding the PFN offset of memory twice.
      
         - A fix from Robin to correct parsing of MPIDR values when the
           address size is larger than one BE32 unit.
      
         - A fix from Srinivas to ensure that we do not rely on the boot
           loader (or previous Linux kernel) setting the translation table
           base register a certain way in the decompressor, which can lead to
           crashes"

      ARM: 8618/1: decompressor: reset ttbcr fields to use TTBR0 on ARMv7 · 117e5e9c
      Srinivas Ramana authored
      If the bootloader uses the long descriptor format and jumps to
      kernel decompressor code, TTBCR may not be in a right state.
      Before enabling the MMU, it is required to clear the TTBCR.PD0
      field to use TTBR0 for translation table walks.
      
      The commit dbece458 ("ARM: 7501/1: decompressor:
      reset ttbcr for VMSA ARMv7 cores") does the reset of TTBCR.N, but
      doesn't consider all the bits for the size of TTBCR.N.
      
      Clear TTBCR.PD0 field and reset all the three bits of TTBCR.N to
      indicate the use of TTBR0 and the correct base address width.

      Pull x86 fixes from Thomas Gleixner:
       "The last regression fixes for 4.8 final:
      
         - Two patches addressing the fallout of the CR4 optimizations which
           caused CR4-less machines to fail.
      
         - Fix the VDSO build on big endian machines
      
         - Take care of FPU initialization if no CPUID is available otherwise
           task struct size ends up being zero
      
         - Fix up context tracking in case load_gs_index fails"
