Merge branch 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm updates from Ingo Molnar:
- Extend the memmap= boot parameter syntax to allow the redeclaration
and dropping of existing ranges, and to support all e820 range types
(Jan H. Schönherr)
- Improve the W+X boot time security checks to remove false positive
warnings on Xen (Jan Beulich)
- Support booting as Xen PVH guest (Juergen Gross)
- Improved 5-level paging (LA57) support, in particular it's possible
now to have a single kernel image for both 4-level and 5-level
hardware (Kirill A. Shutemov)
- AMD hardware RAM encryption support (SME/SEV) fixes (Tom Lendacky)
- Preparatory commits for hardware-encrypted RAM support on Intel CPUs.
(Kirill A. Shutemov)
- Improved Intel-MID support (Andy Shevchenko)
- Show EFI page tables in page_tables debug files (Andy Lutomirski)
- ... plus misc fixes and smaller cleanups
