[PATCH 13/19] arm64: vdso: Include common headers in the vdso library

From: Vincenzo Frascino
Date: Thu Feb 13 2020 - 11:17:49 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.

Refactor the vdso implementation to include common headers.
