Subject: drm/i915: Move global activity tracking from GEM to GT
Git-commit: a2b4dead98ef1241498ff8769c85154995938087
Patch-mainline: v5.5-rc1
References: bsc#1152489
As our global unpark/park keep track of the number of active users, we
can simply move the accounting from the GEM layer to the base GT layer.
It was placed originally inside GEM to benefit from the 100ms extra
delay on idleness, but that has been eliminated and now there is no
substantive difference between the layers. In moving it, we move another
piece of the puzzle out from underneath struct_mutex.
