    arm: Dump additional fault registers in abort handlers
    
    Paging code is tricky and figuring out what is wrong with it can be a
    pain. This patch tries to ease the burden by giving a little more
    information for prefetch and data aborts, dumping the Instruction Fault
    Address Register (IFAR), Instruction Fault Status Register (IFSR) and
    Auxiliary Instruction Fault Status Register (AIFSR) or the respective
    Data registers. These contain additional information about the cause of
    the abort (internal/external, write or read, fault subtype, etc.) and
    the faulting address.
    
    BUG=None
    TEST=I have read through enough imprecise asynchronous external abort
    reports with this patch that I learned the bit pattern by heart.
