Subject: [PATCH AUTOSEL 5.4 024/266] powerpc/kasan: Fix stack overflow by increasing THREAD_SHIFT
Date: Wed, 17 Jun 2020 21:12:29 -0400 [thread overview]
Message-ID: <20200618011631.604574-24-sashal@kernel.org> (raw)
In-Reply-To: <20200618011631.604574-1-sashal@kernel.org>
From: Christophe Leroy <christophe.leroy@c-s.fr>
[ Upstream commit edbadaf0671072298e506074128b64e003c5812c ]
When CONFIG_KASAN is selected, the stack usage is increased.
In the same way as x86 and arm64 architectures, increase
THREAD_SHIFT when CONFIG_KASAN is selected.
Fixes: 2edb16efc899 ("powerpc/32: Add KASAN support")
