Subject: [PATCH 0/3] x86/vdso: Add support for CLOCK_MONOTONIC_RAW in the vDSO

This series adds support for the CLOCK_MONOTONIC_RAW clock in the x86
vDSO, thus decreasing its readout cost.  This is particularly useful
for Wine which needs to implement Win32 API clock functions whose
value does not get adjusted with adjtimex().
