    This patch adds support for decoding ARM oopses to scripts/decodecode.
    The following things are handled:
    
     - ARCH and CROSS_COMPILE environment variables are respected.
    
     - The Code: in x86 oopses is in bytes, while it is in either words (4
       bytes) or halfwords for ARM.
    
     - Some versions of ARM objdump refuse to disassemble instructions
       generated by literal constants (".word 0x...").  The workaround is to
       strip the object file first.
    
     - The faulting instruction is marked (liked so) in ARM, but <like so>
       in x86.
    
     - ARM mnemonics may include characters such as [] which need to be
       escaped before being passed to sed for the "<- trapping instruction"
       substitution.
