This change removes some unneeded updates during task migration
(while locked 2 runqueues) and make some updates
deferred after releasing the lock.
it saves some locking time (nanoseconds though not much)
Please test and let me know if it worths to merge.
Some benchmarks I did for vblank_mode=1 glxgears
the first column (with -dev suffix) is the full deferred patch, the next has only removed update_curr without the deferred stuff, the last two are repeated tests for TT without any changes.
