Having pondered note (1) in my previous email a bit more, I imagine the reason
for using a DMB instead of acq/rel semantics is to prevent accesses following
the STLXR from being reordered between it and the LDAXR.

By default a timestamp gets added to the xen efi binary. Unfortunately
ld doesn't seem to provide a way to set a custom date, like from
SOURCE_DATE_EPOCH, so set a zero value for the timestamp (option
--no-insert-timestamp) if SOURCE_DATE_EPOCH is defined. This makes
reproducible builds possible.
Use the solution described in [1] to replace the call to the 'date'
command with a version that uses SOURCE_DATE_EPOCH if available. This
is needed for reproducible builds.

While working on a reproducible build of xen in Debian I came up with
the following three patches which are needed to build xen reproducibly
in Debian. Reproducible builds are useful to verify the binary has
actually been built from the corresponding source.
The first patch is an extension of [1]

The description "physical CPUs" is especially wrong, as it implies the number
of sockets, which tops out at 8 on all but the very biggest servers.
NR_CPUS is the number of logical entities the scheduler can use.
