[MODERATED] [PATCH v4 0/8] L1TFv4 0

[ak@linux.intel.com]

Here's the updated L1TF native OS patchkit to mitigate speculation
into unmapped PTEs.  This is stabilizing now.

This version has over v3:
- Cleanups/changes from code review
- Fix a bug added with v3 that broke the sysfs reporting

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
