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 arch/x86/include/asm/imr.h | 2 +- arch/x86/platform/intel-quark/imr.c | 26 +++++++------------------- arch/x86/platform/intel-quark/imr_selftest.c | 15 +++++++-------- 3 files changed, 15 insertions(+), 28 deletions(-) -- 2.5.0
