Subject: [PATCH 1/7] linux: Update x86 vDSO symbols
Date: Fri, 29 Nov 2019 21:03:00 -0000 [thread overview]
Message-ID: <20191129210327.26434-1-adhemerval.zanella@linaro.org> (raw)
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.
