     1     NOTE! This copyright does *not* cover user programs that use kernel
     2   services by normal system calls - this is merely considered normal use
     3   of the kernel, and does *not* fall under the heading of "derived work".
     4   Also note that the GPL below is copyrighted by the Free Software
     5   Foundation, but the instance of code that it refers to (the Linux
     6   kernel) is copyrighted by me and others who actually wrote it.
     7  
     8   Also note that the only valid version of the GPL as far as the kernel
     9   is concerned is _this_ particular version of the license (ie v2, not
    10   v2.2 or v3.x or whatever), unless explicitly otherwise stated.
