Detailed Description

Note: the creator of the EI block must set the usage_cnt to 0. The wlat_propagate_event() will put a single lock before propagation and release that lock right after propagation of the token. Extra locks can be set by any of the processing blocks which are the responsible for releasing that lock either before or after the appropriate call to wlat_propagate_event().
See also the 'SPR_WLAT_EI_HOLD', 'SPR_WLAT_EI_UNHOLD' and 'SPR_WLAT_EI_RELEASE' macro calls.
