       mtrr_del - delete a memory type region


       int mtrr_del  (int reg, unsigned long base, unsigned long size);


       reg    Register returned by mtrr_add

       base   Physical base address

       size   Size of region


       If  register  is  supplied  then base and size are ignored. This is how
       drivers should call it.

       Releases an MTRR region. If the usage count drops to zero the  register
       is  freed  and  the  region  returns  to  default state. On success the
       register is returned, on failure a negative error code.
