    x86/cqm: Share PQR_ASSOC related data between CQM and CAT · 6b281569
    Fenghua Yu authored
    PQR_ASSOC MSR contains the RMID used for preformance monitoring of cache
    occupancy and memory bandwidth. The upper 32bit of this MSR contain the
    CLOSID for cache allocation. So we need to share the information between
    the two facilities.
    
    Move the rdt data structure declaration into the shared header file and
    make the per cpu data structure containing the MSR values global.
