Are you not seeing this on v4.0-rc1 without the patchset applied?
Could the crash be inside the subsequent call to SetVirtualAddressMap() instead of inside ExitBootServices()?
If so, you have a firmware bug: Mark Rutland spotted a similar bug in the AMD Seattle firmware, which has been fixed in the mean time. It has to do with the firmware dereferencing the virtual mapping as it is being installed, which violates the UEFI spec.
It looks like you are right. We fixed the bug in our UEFI and now this patchset works.
So all 21 patches:

However, I did notice one thing. Booting the kernel displays this line:
[ 69.424001] Failed to find cpu0 device node
That's because CONFIG_OF is still defined (part of "config ARM64"), and therefore cache_setup_of_node() attempts to get the cache information from the device tree.
Should CONFIG_OF still be defined?
