Some of our users ran into issues with running Ceph on older CPU
architectures [1]. This is apparently due to a bug in gf-complete
paired with gcc-12, that
leads to SSE 4.1 instructions being emitted in the general code,
rather than dynamically dispatching functions using those
instructions. Those binaries then break on older CPUs that do not
support this instruction set.
I've ran some benchmarks with `rados bench` against our last release
(18.2.0-pve2) and this new version. The commands were taken from our
latest Ceph benchmarking paper [2]. The results showed that this patch
does not lead to performance regressions on newer hardware.
