--- Comment #6 from Ahmad Khalifa <vexeduxr@FreeBSD.org> ---
Thank you both for your reports. After the above commits, there shouldn't be
any more page faults in the first page (first 4KiB of memory). For other memory
addresses, the workaround is to reserve a specific memory region for efirt
(note that this would eat into your available memory). See the commit above for
more details.
