Loop through mtrr chunk_size and gran_size from 1M to 2G to find out the optimal value so user does not need to add mtrr_chunk_size and mtrr_gran_size to the kernel command line. If optimal value is not found, print out all list to help select less optimal value. Add mtrr_spare_reg_nr= so user could set 2 instead of 1, if the card need more entries. v2: find the one with more spare entries v3: fix hole_basek offset v4: tight the compare between range and range_new loop stop with 4g Signed-off-by: NYinghai Lu <yhlu.kernel@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Gabriel C <nix.or.die@googlemail.com> Cc: Mika Fischer <mika.fischer@zoopnet.de> Signed-off-by: NThomas Gleixner <tglx@linutronix.de> Signed-off-by: NIngo Molnar <mingo@elte.hu>
