case SMMU_CMD_CFGI_CD:
If the whole SID range (32b) is invalidated (SMMU_CMD_CFGI_ALL), @end overflows and we fail to handle the command properly. Once this gets fixed, the current code really is awkward in the sense it loops over the whole range instead of removing the currently cached configs through a hash table lookup. Fix both the overflow and the lookup.
