Pull ARM updates from Russell King:
 "ARM development updates:

   - more unified assembly conversions for clang

   - drop obsolete -mauto-it assembler option

   - remove arm_memory_present in preference to the generic version

   - remove unused asm/limits.h header

   - vdso linker update

  We tried to make the assembler warn if unified syntax was not used,
  but unfortunately older versions of GCC warn, so the commit had to be
  reverted"
