Subject: [PATCH v3 0/2] x86, mtrr: fixs for mtrr_cleanup

Joshua reported: Commit cd7b304dfaf1 (x86, range: fix missing merge
during add range) broke mtrr cleanup on his setup in 3.9.5.
corresponding commit in upstream is fbe06b7bae7c.

  *BAD*gran_size: 64K chunk_size: 16M num_reg: 6 lose cover RAM: -0G

https://bugzilla.kernel.org/show_bug.cgi?id=59491

Fix it from two places, so late mtrr cleanup side and range add side.

  x86, mtrr: Fix original mtrr range get for mtrr_cleanup
  range: Do not add new blank slot with add_range_with_merge

Please apply them for v3.10.

Thanks

Yinghai
