KVM: MTRR: sort variable MTRRs
Sort all valid variable MTRRs based on its base address, it will help us to check a range to see if it's fully contained in variable MTRRs Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> [Fix list insertion sort, simplify var_mtrr_range_is_valid to just test the V bit. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
