This series seems to break 'make check-acceptance':

UEFI runs in the guest and seems to launch the kernel, but there's
no output from the kernel itself in the logfile. Last thing it
prints is:

EFI stub: Booting Linux Kernel...
EFI stub: EFI_RNG_PROTOCOL unavailable, no randomness supplied
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map...

This ought to be followed by the usual kernel boot log
[    0.000000] Booting Linux on physical CPU 0x0000000000 [0x000f0510]
etc but it isn't. Probably the kernel is crashing in early bootup
before it gets round to printing anything.
