arm: Introduce asm/vdso/clocksource.h

2020-03-21T14:23:54Z

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.

ARM/arm64: vdso: Use common vdso clock mode storage

2020-02-17T19:12:16Z

Convert ARM/ARM64 to the generic VDSO clock mode storage. This needs to happen in one go as they share the clocksource driver. Signed-off-by: Thomas Gleixner Tested-by: Vincenzo Frascino Reviewed-by: Vincenzo Frascino Link: https://lkml.kernel.org/r/20200207124403.363235229@linutronix.de

arm/arm64: arch_timer: Use archdata to indicate vdso suitability

2016-09-23T16:19:25Z

Instead of comparing the name to a magic string, use archdata to explicitly communicate whether the arch timer is suitable for direct vdso access. Acked-by: Will Deacon Acked-by: Russell King Acked-by: Marc Zyngier Signed-off-by: Scott Wood Signed-off-by: Will Deacon
