Yinghai Lu d8d386c106 x86, mtrr: Fix original mtrr range get 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 fbe06b7bae. *BAD*gran_size: 64K chunk_size: 16M num_reg: 6 lose cover RAM: -0G https://bugzilla.kernel.org/show_bug.cgi?id=59491 So it rejects new var mtrr layout. It turns out we have some problem with initial mtrr range retrieval. The current sequence is: x86_get_mtrr_mem_range ==> bunchs of add_range_with_merge ==> bunchs of subract_range ==> clean_sort_range add_range_with_merge for [0,1M) sort_range() add_range_with_merge could have blank slots, so we can not just sort only, that will have final result have extra blank slot in head. So move that calling add_range_with_merge for [0,1M), with that we could avoid extra clean_sort_range calling.
