Subject: [PATCH AUTOSEL 4.19 33/53] powerpc/vdso32: fix CLOCK_MONOTONIC on PPC64
Date: Fri, 26 Apr 2019 21:40:30 -0400 [thread overview]
Message-ID: <20190427014051.7522-33-sashal@kernel.org> (raw)
In-Reply-To: <20190427014051.7522-1-sashal@kernel.org>
From: Christophe Leroy <christophe.leroy@c-s.fr>
[ Upstream commit dd9a994fc68d196a052b73747e3366c57d14a09e ]
Commit b5b4453e7912 ("powerpc/vdso64: Fix CLOCK_MONOTONIC
inconsistencies across Y2038") changed the type of wtom_clock_sec
to s64 on PPC64. Therefore, VDSO32 needs to read it with a 4 bytes
shift in order to retrieve the lower part of it.
Fixes: b5b4453e7912 ("powerpc/vdso64: Fix CLOCK_MONOTONIC inconsistencies across Y2038")
