As discussed with Rafael privately, I also tried this very patch (x86/power/64: Always create temporary identity mapping correctly) on top of the reverted revert of 021182e52fe01c1f7b1 (see the full log below), but such kernel triple faults on resume as well. 87c38d2 x86/power/64: Always create temporary identity mapping correctly 3cb504a Revert "Revert "x86/mm: Enable KASLR for physical mapping memory regions"" 758850d Revert "x86/mm: Enable KASLR for physical mapping memory regions" 4a02dfb Revert "x86/mm: Enable KASLR for vmalloc memory regions" 037863f Revert "x86/mm: Add memory hotplug support for KASLR memory randomization" 3416a21 Revert "x86/mm: Do not reference phys addr beyond kernel" 69227be Revert "mm: reorganize SLAB freelist randomization" a1d8d71 Revert "mm: SLUB freelist randomization" IOW, 021182e52f introduces a bug for which there is no existing fix yet. -- Jiri Kosina SUSE Labs
