arm64: vdso: Include common headers in the vdso library

fvincenzo · KAGA-KOKO · commit 60ad903e9477 · 2020-03-21T15:24:01.000+01:00
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.
