Subject: m68knommu: start dump from exception stack
X-Git-Tag: upstream/snapshot3+hdmi~32234
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a4c8b9159000018b0c641b844795a4de4e954582;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

m68knommu: start dump from exception stack

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.
