i'm hitting this when rebooting with your patchset applied...
Rebooting. [ 236.260863] Kernel panic - not syncing: HYP panic: [ 236.260863] PS:600003c9 PC:000003ffffff0830 ESR:0000000096000006
It would be interesting if you could find out what you have at offset 0x830 of hyp-init.o (the stack trace is for EL1, and is not going to help much).
Thanks,
