You'll have to elaborate a bit here and explain that this is sufficient, given that we run EFI runtime services with interrupts enabled.I can add a note about this in v2. This is called with preemption disabled and we have a separate interrupt shadow stack, so as far as I can tell, this should be sufficient. Did you have concerns about this?
No concerns, but we should put the above clarification in the commit log. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
