      ARM: 8918/2: only build return_address() if needed · fb033c95
      Ben Dooks authored
      The system currently warns if the config conditions for
      building return_address in arch/arm/kernel/return_address.c
      are not met, leaving just an EXPORT_SYMBOL_GPL(return_address)
      of a function defined to be 'static linline'.
      This is a result of aeea3592 ("ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.h").
      
      Since we're not going to build anything other than an exported
      symbol for something that is already being defined to be an
      inline-able return of NULL, just avoid building the code to
      remove the following warning:

      ARM: 8915/1: zImage: atags_to_fdt: fix __be32 and __be64 types · 43fa593e
      Ben Dooks (Codethink) authored
      There are some sparse warnings about type conversion in
      the atags_to_fdt.c code, due to __be32 and __be64, so
      fix the following:
      
      - Change _be32 and __be64 where appropriate
      - Change setprop() to take a 'void *'
      - Change incorrect fdt32_to_cpu() on FDT_MAGIC
