[PATCH 0/2] Fixes for s3 with parallel bootup

Posted by Mario Limonciello 2 years, 2 months ago

Parallel bootup on systems that use x2apic broke suspend to ram.
This series ensures x2apic is re-enabled at startup and fixes an exposed
pre-emption issue.

Mario Limonciello (2):
  x86: Enable x2apic during resume from suspend if used previously
  perf/x86/amd: Don't allow pre-emption in amd_pmu_lbr_reset()
