KVM: MTRR: introduce fixed_mtrr_addr_* functions

Browse source

Two functions are introduced:
- fixed_mtrr_addr_to_seg() translates the address to the fixed
  MTRR segment

- fixed_mtrr_addr_seg_to_range_index() translates the address to
  the index of kvm_mtrr.fixed_ranges[]

They will be used in the later patch
