*/ SOC: Remove most of LSMASK=.TRUE. lines from TSTMSK
*/
*/ This modset can be used in all configurations. It rejects requests
*/ for some unavailable STASH items where before, the request was not
*/ rejected.
*/ TSTMSK initialises LSMASK to TRUE at top, so no other LSMASK=.TRUE.
*/ are required. Some that were removed were bugs that reversed a
*/ preceding setting to false (eg GSS3F401.1462 and ACN2F405.14)
*/ others that were removed were superfluous and confusing - people
*/ making changes were copying the logic and introducing bugs.
