* Miscellaneous fixes - handle HSA OnLoad called during omnitrace-avail - disable setting HSA_ENABLE_INTERRUPT when roctracer not used - sampler max verbose - fix roctracer get_clock_skew - cleanup roctracer debug output - update timemory submodule with fence - simplify min-instructions vs. min-address-range specification - exclude cxx regex updates - disable HSA_TOOLS_LIB and HSA_ENABLE_INTERRUPT when no roctracer * git safe.directory
