Subject: [PATCH] systemd/gnome-shell-mobile: add uclamp hack
This is a hack to configure utilisation clamping for gnome-shell. It
works by telling the scheduler that the gnome-shell process should run
with a much higher performance level. This improve animation performance
and general UI smoothness. A proper solution to have gnome-shell manage
this itself is in the works upstream.
