; Example: if low part of physical memory is 3.5G = 0xE0000000 bytes wide,
; BIOS can configure two MTRRs so that the first MTRR describes [0, 4G) as WB
; and the second MTRR describes [3.5G, 4G) as UC;
; WB+UC=UC, so the resulting memory map would be as needed,
; but in this configuration our attempts to map LFB at (say) 0xE8000000 as WC
; would be ignored, WB+UC+WC is still UC.
; So we must keep top of 4G memory not covered by MTRRs,
; using three WB MTRRs [0,2G) + [2G,3G) + [3G,3.5G),
; this gives the same memory map, but allows to add further entries.
