Subject: [PATCH v13 8/8] powerpc/vdso: Provide __kernel_clock_gettime64() on vdso32
Date: Tue,  3 Nov 2020 18:07:19 +0000 (UTC)	[thread overview]
Message-ID: <44a5541c0355b9eedbac712eabe682118b3a508c.1604426550.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1604426550.git.christophe.leroy@csgroup.eu>

Provides __kernel_clock_gettime64() on vdso32. This is the
64 bits version of __kernel_clock_gettime() which is
y2038 compliant.
