Hi Daisuke,
It looks that this is useful regardless of crash dump mechanism such as VMware, virsh
dump, sadump and so on.
Should be in kaslr_helper.c.
Agree. It can be added later after introduction of pc->get_register(cpu, regno) API, so
high-level code such as kaslr_helper.c can use it.
As of now, backup method (page tree walking) implemented in this patch set will handle
zeroed IDTR.
Thanks,
—Alexey
