[MODERATED] [PATCH 0/5] Slow Randomizing Boosts DoS v4.4.219 backport 0

Subject: [PATCH 0/5] Slow Ranomizing Boosts DoS linux-4.4.y backport

This is a backport of the backports done by Thomas for linux-4.14.y to
linux-4.4.y.

The backport needed a backport of one additional dependency for
cpu_data-x86_mask getting renamed to x86_stepping.

This was tested by the test engineer who tested the other SRBDS implementations
and it seems to work.


Jia Zhang (1):
  x86/cpu: Rename cpu_data.x86_mask to cpu_data.x86_stepping

Mark Gross (4):
  x86/cpu: Add a steppings field to struct x86_cpu_id
  x86/cpu: Add 'table' argument to cpu_matches()
  x86/speculation: Add Special Register Buffer Data Sampling (SRBDS)
    mitigation
  x86/speculation: Add SRBDS vulnerability and mitigation documentation
