Hi,

Strictly speaking those two patches are independent, but I figured it would
make sense to send them together (since one led to the other).

Patch 1 adds a sanity check against EAS + SMT.
Patch 2 enables CONFIG_SCHED_SMT in the arm64 defconfig.

Cheers,
Valentin

Revisions
=========

v1 -> v2
--------
o Collected Reviewed-by, Acked-by (Dietmar, Quentin)
o Added a warning when disabling EAS due to SMT (Dietmar)

Valentin Schneider (2):
  sched/topology: Don't enable EAS on SMT systems
