gem5/arch/alpha/alpha_tru64_process.cc
Gabe Black 2939a7089a byte_swap.hh was removed from arch/alpha/, and replaced by sim/byteswap.hh. The new file uses LittleEndianGuest and BigEndianGuest namespaces to allow selecting the appropriate functions. 
arch/alpha/alpha_linux_process.cc:
arch/alpha/alpha_tru64_process.cc:
    Added the endianness namespace. This may change.
cpu/exec_context.hh:
    Changed the include path for byteswap, and forced LittleEndianness for lack of a better solution.
cpu/o3/alpha_cpu.hh:
    Forced LittleEndianness, for lack of a better solution.
cpu/o3/alpha_cpu_impl.hh:
    Cleared away some commented out code.
cpu/o3/fetch_impl.hh:
    Changed the include patch for byteswap, and forced LittleEndianness for lack of a better solution.
cpu/simple/cpu.cc:
    Added an include for byteswap.hh, and fixed the SimpleCPU to LittleEndian. This cpu only does alpha, so that's fine.
dev/disk_image.cc:
    Changed the include path of byteswap.hh
kern/freebsd/freebsd_system.cc:
kern/linux/linux_system.cc:
    Added an include for byteswap.hh, and forced LittleEndianness for lack of a better solution.
sim/system.cc:
    Forced LittleEndianness for lack of a better solution.
