sys/i386/i386 exception.s
Log:
Fixed restoring of cpl after trap handling. The wrong cpl (SWI_AST_MASK
instead of 0) was "restored" after handling a trap that occurred while
returning to user mode. This bug was most noticeable for VM86 and is
still detected and fixed up (on return from the next exception) in doreti
if VM86 is configured.
