arch/sparc/linux_process.cc:
arch/sparc/linux_process.hh:
    Formatting & doxygen.
arch/sparc/linux_process.cc:
    Added some more ioctl commands to ignore.
    Set unlink and rename to the new functions.
    Ignore setrlimit, times and rt_sigaction.
    Should eventually provide a function for times.
arch/sparc/linux_process.cc:
    Fixes for Linux emulation:
    - stat struct alignment
    - osf_{get,set}sysinfo return values
    - additional syscall numbers
    - initialize $r0 to 0
arch/sparc/linux_process.cc:
arch/sparc/linux_process.hh:
    Updated Copyright
arch/sparc/linux_process.cc:
    Alphabetize includes.
arch/sparc/linux_process.cc:
    Changed all syscalls to use syscall return object
arch/sparc/linux_process.cc:
    Removed unecessary constructor call at each return.
arch/sparc/linux_process.cc:
    Rename sim/universe.{cc,hh} to root.{cc,hh}.
arch/sparc/linux_process.cc:
    shuffle files around for new directory structure
arch/sparc/linux_process.cc:
    Remove RCS Id string
arch/sparc/linux_process.cc:
arch/sparc/linux_process.hh:
    Update copyright dates and author list
arch/sparc/linux_process.hh:
    remove $Id$ string
arch/sparc/linux_process.cc:
    Apply patch for syscall emulation provided by Antti Miettinen (apm@brigitte.dna.fi).
arch/sparc/linux_process.cc:
    Added the endianness namespace. This may change.
arch/sparc/linux_process.cc:
    Replaced the namespace declaration with including arch/alpha/isa_traits.hh
arch/sparc/linux_process.cc:
    fixup for bsd hosts. Some headers are included by default which means that
    more variables need TGT_ prefixes and there isn't a stat call (everything
    is a stat64 call) so we have to work around that a bit
arch/sparc/linux_process.cc:
    Add endian conversions to fstat
arch/sparc/linux_process.cc:
    fix #if. I wonder why my compiler had no issues
arch/sparc/linux_process.cc:
    add endian conversions for fstat functions
arch/sparc/linux_process.cc:
    move architecture independent code into kern/linux/linux.(hh|cc)
arch/sparc/linux_process.hh:
    Add getDesc function
arch/sparc/linux_process.cc:
    Added using directive for AlphaISA namespace
arch/sparc/linux_process.cc:
    Add pipeFunc.
arch/alpha/linux_process.cc:
    Renamed arch files to remove alpha prefix, and changed alpha_memory.hh and cc to a more accurate tlb.hh and cc
arch/sparc/linux_process.cc:
    bk cp ../alpha/linux_process.cc linux_process.cc
arch/sparc/linux_process.hh:
    bk cp ../alpha/linux_process.hh linux_process.hh
