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_version=host -smp 7 -m 2048 -cpu host,aarch64=off -nographic -pflash AAVMF32_CODE.fd -pflash AAVMF32_VARS.fd -drive if=none,file=bionic-server-cloudimg-armhf.img,id=hd0 -device virtio-blk-device,drive=hd0 -drive if=none,file=my-seed.img,id=hd1 -device virtio-blk-device,drive=hd1 -drive if=none,file=debian.img,id=hd3 -device virtio-blk-device,drive=hd3 -netdev type=tap,id=net0 -device virtio-net-device,netdev=net0,mac=<REDACTED>

[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.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-cosmic' to 'verification-done-cosmic'. If the problem still exists, change the tag 'verification-needed-cosmic' to 'verification-failed-cosmic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
