[MODERATED] [PATCH 0/8] L1TFv3 4

[Andi Kleen <ak@linux.intel.com>]

This is v3 of the core VM L1 OS mitigation.

- Addressed review comments
- Fixed a bug on 32bit PAE that prevented setting all needed
  bits to protect the full host memory.
- Added a new patch to forbid PROT_NONE high MMIO again. We found some systems
  where it is needed. This version tries to minimize any breakage by
  limiting the check to non root only, and only refusing the PROT_NONE
  when the underlying MMIO address is actually high.

Andi Kleen (7):
  x86, l1tf: Increase 32bit PAE __PHYSICAL_PAGE_MASK
  x86, l1tf: Protect PROT_NONE PTEs against speculation
  x86, l1tf: Make sure the first page is always reserved
  x86, l1tf: Add sysfs reporting for l1tf
  x86, l1tf: Report if too much memory for L1TF workaround
  x86, l1tf: Limit swap file size to MAX_PA/2
  mm, l1tf: Disallow non privileged high MMIO PROT_NONE mappings

Linus Torvalds (1):
  x86, l1tf: Protect swap entries against L1TF
