Subject: [PATCH AUTOSEL 4.19 43/83] powerpc/8xx: fix setting of pagetable for Abatron BDI debug tool.
Date: Tue, 12 Feb 2019 21:36:21 -0500 [thread overview]
Message-ID: <20190213023701.20286-43-sashal@kernel.org> (raw)
In-Reply-To: <20190213023701.20286-1-sashal@kernel.org>
From: Christophe Leroy <christophe.leroy@c-s.fr>
[ Upstream commit fb0bdec51a4901b7dd088de0a1e365e1b9f5cd21 ]
Commit 8c8c10b90d88 ("powerpc/8xx: fix handling of early NULL pointer
dereference") moved the loading of r6 earlier in the code. As some
functions are called inbetween, r6 needs to be loaded again with the
address of swapper_pg_dir in order to set PTE pointers for
the Abatron BDI.
Fixes: 8c8c10b90d88 ("powerpc/8xx: fix handling of early NULL pointer dereference")
