Subject: [PATCH v2 0/2] Fixes for s3 with parallel bootup

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: Stop calling amd_pmu_cpu_reset() from amd_pmu_cpu_dead()
