in 3.2K.

+ Arnaldo Carvalho de Melo <acme@conectiva.com.br> fix issues
+ related to save_flags/restore_flags, some restore_flags and
+ DvcLeaveCritical were missing, use unsigned long flags instead
+ of int flags, a not needed cli commented out, like the sti
+ that matches it (in advansys_abort) - 08/01/2001
