Subject: [M68KNOMMU]: fix syscall restart handling
Date: Tue, 23 Oct 2007 14:37:54 +1000 [thread overview]
Message-ID: <200710230437.l9N4bs4a001796@goober> (raw)
Fix system call restart handling. We can call directly to the
restart handler, no need to back track through trap that isn't
even implemented on m68knommu.
