[PATCH v5 07/26] mips: Introduce asm/vdso/clocksource.h

From: Vincenzo Frascino
Date: Fri Mar 20 2020 - 10:55:14 EST


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.
