    Subject[patch 0/5] access_process_vm device memory access
    In order to be able to debug things like the X server and programs
    using the PPC Cell SPUs, the debugger needs to be able to access
    device memory through ptrace and /proc/pid/mem.

    Changelog:
    - use CONFIG_HAVE_IOREMAP_PROT
    - do not use generic_access_phys as a fallback but define it in
    the ->vm_ops->access for appropriate VMAs
    - other code cleanups suggested by Andrew Morton and Sam Ravnborg
