This series includes bug fixes and cleanups for the Intel uncore PMU
driver.

- Patch 1 fixes a theoretical bug in discovery unit lookup on multi-die
  systems.
- Patch 2 guards against an invalid box control address.
- Patch 3 fixes a PCI device refcount leak in UPI topology discovery.
- Patch 4 works around a hardware issue on Raptor Cove CPUs.
- Patches 5-7 implement a global MSR init callback for GNR/GRR/SRF/CWF
  uncore.

Changes in v2:
- Add patch 2 to guard against invalid box control address (Sashiko)
- Remove WARN_ON_ONCE() from patch 1
- Move cpus_read_{lock,unlock}() out of uncore_die_to_cpu() (Sashiko)
