Subject: [GIT PULL] scheduler updates for v4.20

Linus,

Please pull the latest sched-core-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-for-linus

   # HEAD: 11e13696a08e838ba48c72404c2b3f41429b5b20 sched/completions/Documentation: Add recommendation for dynamic and ONSTACK completions

The main changes are:

 - Migrate CPU-intense 'misfit' tasks on asymmetric capacity systems, to 
   better utilize (much) faster 'big core' CPUs.
   (Morten Rasmussen, Valentin Schneider)

 - Topology handling improvements, in particular when CPU capacity 
   changes and related load-balancing fixes/improvements (Morten Rasmussen)

 - ... plus misc other improvements, fixes and updates.

 Thanks,

	Ingo
