            Bug ID: 240180
           Summary: Stop abusing __pcpu in bhyve
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bhyve
          Assignee: virtualization@FreeBSD.org
          Reporter: jhb@FreeBSD.org

In the case of &__pcpu[curcpu], it would be better to use PCPU_GET(prvspace=
).=20
curcpu is already PCPU_GET(cpuid), so getting prvspace is probably fewer
instructions, but it also avoids bhyve assuming details about how pcpu
structures are allocated.
