Bug Description
[Impact]
The fix for bug 1786878 introduced a regression that causes armhf guest booted in EFI mode to panic.
[Test Case]
Boot an armhf guest in EFI mode. Here's how I do that on an arm64 box that supports AArch32:
sudo qemu-system-aarch64 -enable-kvm -M virt,gic_
[Fix]
33412b8673135 efi/arm: Revert deferred unmap of early memmap mapping
[Regression Risk]
This change is specific to efi/arm, which currently doesn't boot. The reverted change was to allow for ACPI BGRT code, which isn't supported on 32-bit ARM.
