[PATCH v2 0/3] Add lockdown mode

[Kevin Lampis <kevin.lampis@xxxxxxxxx>]

The intention of lockdown mode is to prevent attacks from a rogue dom0
userspace from compromising the system. Lockdown mode can be controlled by a
Kconfig option and a command-line parameter. It is also enabled automatically
when Secure Boot is enabled and it cannot be disabled in that case.

Ross Lagerwall (2):
  efi: Add a function to check if Secure Boot mode is enabled
  Add lockdown mode

Kevin Lampis (1):
  Disallow most command-line options when lockdown mode is enabled
