Patrick Georgi a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

You need to be ROOT or use SUDO to execute MSRTOOL.

Note that you need /dev/cpu/*/msr available to run msrtool in Linux.


syntax: msrtool [-hvqrkl] [-c cpu] [-m system] [-t target ...]
         [-i addr=hi[:]lo] | [-s file] | [-d [:]file] | addr...
  -h     show this help text                                                                                                                  
  -v     be verbose                                                                                                                           
  -q     be quiet (overrides -v)
  -r     include [Reserved] values
  -k     list all known systems and targets
  -l     list MSRs and bit fields for current target(s) (-kl for ALL targets!)
  -c     access MSRs on the specified CPU, default=0
  -m     force a system, e.g: -m linux
  -t     force a target, can be used multiple times, e.g: -t geodelx -t cs5536
  -i     immediate mode
         decode hex addr=hi:lo for the target without reading hw value
         e.g: -i 4c00000f=f2f100ff56960004
  -s     stream mode
         read one MSR address per line and append current hw value to the line
         use the filename - for stdin/stdout
         using -l -s ignores input and will output all MSRs with values
  -d     diff mode
         read one address and value per line and compare with current hw value,
         printing differences to stdout. use the filename - to read from stdin
         use :file or :- to reverse diff, normally hw values are considered new
  addr.. direct mode, read and decode values for the given MSR address(es)


Examples:

msrtool 0x20000018

./msrtool 0x200000{18,19,1a,1b,1c,1d} 0x4c0000{0f,14}
