Optimize sys_old_mmap * mem.c (sys_old_mmap): For Ia64 and 32-bit personality of x86-64, copy narrow parameters from userspace by single umove, not by six separate ones; then assign them to long u_arg[i]. For SH[64], avoid copying of tcp->u_arg. (sys_mmap): Add FIXME comment - SH64 and i386 seem to be handled differently for no apparent reason. * test/mmap_offset_decode.c: New test program, illustrates FIXME.
