[MODERATED] [PATCH 0/8] L1TFv7 3

[ak@linux.intel.com]

This is the native OS mitigation for L1TF attacks using page table inversion,
and adding the sysfs reporting.

Additional mitigations are still needed for KVM.

Addresses all left over review comments. Only very minor changes compared
to last version.

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

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