[PATCH v3 0/2] x86/vdso: CLOCK_MONOTONIC_RAW implementation

[Sverdlin, Alexander (Nokia - DE/Ulm)]

From: Alexander Sverdlin <alexander.sverdlin@xxxxxxxxx>

Trivial vDSO implementation saves a syscall and brings 700% performance
boost of clock_gettime(CLOCK_MONOTONIC_RAW, ...) call.

Changelog:
v3: Move mult and shift into struct vgtod_ts
v2: copy do_hres() into do_monotonic_raw()

Alexander Sverdlin (2):
  x86/vdso: Move mult and shift into struct vgtod_ts
  x86/vdso: implement clock_gettime(CLOCK_MONOTONIC_RAW, ...)
