Not totally sure what kind of incompatibility this was triggering in
userspace since Zygote crashed during early boot and we never really
booted properly.
F DEBUG : Abort message: 'Check failed: errno == ENOSYS || errno == EACCES userfaultfd: Invalid argument'
As of [1], this was enabled to maintain compatibility with FCM lvl 6,
however, even with ACK merged in, this config isn't referenced on any
of the msm-5.4 devices. Google does enable it on 5.10 but that's it.
There is a very clear possibility that we are missing patches from our
kernel which is stuck in the android11 feature branch thanks to GRF.
So let's not build userfaultfd.o for now until we find the patches we
could potentially be missing.
