It could use some cleanup, but looks good.

Acked-by: Peter Stuge <peter at stuge.se>

With some cleanup.

+/* setting up variable and fixed mtrr
+ *
+ * From Intel Vol. III Section 9.12.4, the Range Size and Base Alignment has some kind of requirement:
+ *	1. The range size must be 2^N byte for N >= 12 (i.e 4KB minimum).
+ *	2. The base address must be 2^N aligned, where the N here is equal to the N in previous
+ *	   requirement. So a 8K range must be 8K aligned not 4K aligned.
+ *
+ * These requirement is meet by "decompositing" the ramsize into Sum(Cn * 2^n, n = [0..N], Cn = [0, 1]).
+ * For Cm = 1, there is a WB range of 2^m size at base address Sum(Cm * 2^m, m = [N..n]).
+ * A 124MB (128MB - 4MB SMA) example:
+ * 	ramsize = 124MB == 64MB (at 0MB) + 32MB (at 64MB) + 16MB (at 96MB ) + 8MB (at 112MB) + 4MB (120MB).
+ * But this wastes a lot of MTRR registers so we use another more "aggresive" way with Uncacheable Regions.
+ *
+ * In the Uncacheable Region scheme, we try to cover the whole ramsize by one WB region as possible,
+ * If (an only if) this can not be done we will try to decomposite the ramesize, the mathematical formula
+ * whould be ramsize = Sum(Cn * 2^n, n = [0..N], Cn = [-1, 0, 1]). For Cn = -1, a Uncachable Region is used.
+ * The same 124MB example:
+ * 	ramsize = 124MB == 128MB WB (at 0MB) + 4MB UC (at 124MB)
+ * or a 156MB (128MB + 32MB - 4MB SMA) example:
+ *	ramsize = 156MB == 128MB WB (at 0MB) + 32MB WB (at 128MB) + 4MB UC (at 156MB)
