Subject: [PATCH][RESEND] m68knommu: start dump from exception stack
Date: Thu, 19 Jul 2007 09:30:14 +1000 [thread overview]
Message-ID: <200707182330.l6INUEeW014893@goober> (raw)
In die_if_kernel() start the stack dump at the exception-time SP, not
at the SP with all the saved registers; the stack below exception-time
sp contains only exception-saved values and is already printed in
details just before.
