[PATCH v3 0/2] x86/intel/imr: Fix IMR lock logic

[Bryan O'Donoghue]

This patchset changes the lock logic for Isolated Memory Regions. As a
result of a conversation with Andriy we determined that the IMR associated
with the kernel .text section should be unlocked so that kernels executed
by kexec could tear-down the old kernel IMR and setup a new one. On
subsequent discussions with Ingo we discussed removing lock bit support in
totality to simplify the IMR interface. This patchset implements both of
those changes.

V1:
Set the kernel IMR lock bit to false - Bryan

V2:
Make a parameter of the kernel IMR lock logic - Andriy

V3:
Revert to setting the kernel IMR lock bit to false - Ingo
Drop IMR lock bit support - Ingo

Bryan O'Donoghue (2):
  x86/intel/imr: Change the kernel's IMR lock bit to false
  x86/intel/imr: Drop IMR lock bit support
