This series was originally by Mian Yousaf Kaukab.

Arm64 machines should be displaying a human readable
vulnerability status to speculative execution attacks in
/sys/devices/system/cpu/vulnerabilities 

This series enables that behavior by providing the expected
functions. Those functions expose the cpu errata and feature
states, as well as whether firmware is responding appropriately
to display the overall machine status. This means that in a
heterogeneous machine we will only claim the machine is mitigated
or safe if we are confident all booted cores are safe or
mitigated. Otherwise, we will display unknown or unsafe
depending on how much of the machine configuration can
be assured.

v1->v2:
	Add "Unknown" state to ABI/testing docs.
	Minor tweaks.
	
Jeremy Linton (3):
  sysfs/cpu: Add "Unknown" vulnerability state
  arm64: add sysfs vulnerability show for meltdown
  arm64: add sysfs vulnerability show for spectre v2

Mian Yousaf Kaukab (4):
  arm64: kpti: move check for non-vulnerable CPUs to a function
  arm64: add sysfs vulnerability show for spectre v1
  arm64: add sysfs vulnerability show for speculative store bypass
  arm64: enable generic CPU vulnerabilites support
