The current version of the multiarch vDSO selftest verifies only gettimeofday.
Extend the vDSO selftest to clock_getres, to verify that the syscall and the vDSO library function return the same information.
The extension has been used to verify the hrtimer_resoltion fix.
This is passing for me even without patch 1 applied, shouldn't it fail without the fix? What am I missing?
# uname -r 5.2.0-rc2-gcc-8.2.0
# ./vdso_clock_getres clock_id: CLOCK_REALTIME [PASS] clock_id: CLOCK_BOOTTIME [PASS] clock_id: CLOCK_TAI [PASS] clock_id: CLOCK_REALTIME_COARSE [PASS] clock_id: CLOCK_MONOTONIC [PASS] clock_id: CLOCK_MONOTONIC_RAW [PASS] clock_id: CLOCK_MONOTONIC_COARSE [PASS]
cheers

Note: This patch is independent from the others in this series, hence it can be merged singularly by the kselftest maintainers.
