Modified files:
sys/i386/isa cy.c
Log:
Restored the call to schedsofttty() (now spelled swi_sched(...)) again.
Its restoration in rev.1.102 was mistranslated to the equivalent of
setsofttty() in rev.1.105. This increased overheads by causing a
context switch to the SWI handler after almost every interrupt. The
increase was approx. 50% on a Celeron 366 (from 23 usec to 34 usec
per interrupt).
