Vincenzo Frascino	c16b270b17	arm: Introduce asm/vdso/clocksource.h ... The vDSO library should only include the necessary headers required for a userspace library (UAPI and a minimal set of kernel headers). To make this possible it is necessary to isolate from the kernel headers the common parts that are strictly necessary to build the library. Introduce asm/vdso/clocksource.h to contain all the arm64 specific functions that are suitable for vDSO inclusion. This header will be required by a future patch that will generalize vdso/clocksource.h.

Thomas Gleixner	5e3c6a312a	ARM/arm64: vdso: Use common vdso clock mode storage ... Convert ARM/ARM64 to the generic VDSO clock mode storage. This needs to happen in one go as they share the clocksource driver.

Scott Wood	1d8f51d41f	arm/arm64: arch_timer: Use archdata to indicate vdso suitability ... Instead of comparing the name to a magic string, use archdata to explicitly communicate whether the arch timer is suitable for direct vdso access.
