arch/alpha/alpha_linux_process.cc: arch/alpha/alpha_tru64_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 base/intmath.hh: base/socket.cc: this is no longer needed with mac os 10.4 cpu/inst_seq.hh: just use a uint64_t instead of long long cpu/o3/inst_queue_impl.hh: I much cleaner way to get max int sim/syscall_emul.hh: fix stat64 problems on *BSD --HG-- extra : convert_revision : 9eef5f896e083ae1774e818a9765dd83e0305942
