    [PATCH] NFS server as a module with -mregparm=3
    
    This patch makes it possible to compile the nfs server as a module, with
    -mregparm=3 (at least on x86).
    
    Such a combination did not work, as handle_sys_nfsservctl was called
    from the sys_nfsservctl function (in fs/filesystems.c) with parameters
    in registers, but tried to read them from the stack.
