This is the third version of the arm64 PAN emulation using TTBR0_EL1 switching. The series has not yet included the alternative nop patches from Mark Rutland, nor the empty_zero_page from Ard B. This will be done in a subsequent version once 4.9-rc1 is out (which will include Mark's alternative nop patches).I've tested these with a bunch of reboots in both qemu and HiKey and have not seen the efi failure.
Thanks for testing. I'll defer adding your tested-by until I post the hopefully final version after 4.9-rc1 (it's pretty late to merge these patches now, I still need to do more testing on models with PAN or PAN+UAO present). -- Catalin
