Merge tag 'x86_mtrr_for_v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mtrr updates from Borislav Petkov:
"A serious scrubbing of the MTRR code including adding a new map
mechanism in order to look up the memory type of a region easily.
Also address memory range lookup issues like returning an invalid
memory type. Furthermore, this handles the decoupling of PAT from MTRR
more naturally.
All work by Juergen Gross"
