Subject: [PATCH 04/16] linux: Update x86 vDSO symbols
Date: Tue, 17 Dec 2019 18:47:16 -0300	[thread overview]
Message-ID: <20191217214728.2886-4-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20191217214728.2886-1-adhemerval.zanella@linaro.org>

Add the missing time and clock_getres vDSO symbol names on x86.
For time, the iFUNC already uses expected name so it affects only
the static build.

The clock_getres is a new implementation added on Linux 5.3
(f66501dc53e72).

Checked on x86-linux-gnu and i686-linux-gnu.
