IPA causes weird performance/smoothness issues

Disabling REMOTEPROC support seems to speed up the perceived UI snappines by an insane amount for some reason (as tested on GNOME)??

As this also seems to happen when #15 (Sometimes modem just crashes on boot and cannot recover) occurs, perhaps a modprobe.blacklist=qcom_q6v5_mss on cmdline could also cause this perceived smoothness?

This seems to have come down to the IPA module, as a "workaround" once can disable probing of the module with modprobe.blacklist=ipa at the cost of no cellular modem functionality; IPA apparently takes up a lot of bandwidth so the voting paths need to be double-checked...

ipa being probed also seems to result in a bunch of other fun things like poweroff simply not powering the device off as well as causing #2.

• Some benchmarks (UnixBench whets & dhry)
