[PATCH 06/19] linux/time32.h: Extract common header for vDSO
From: Vincenzo Frascino
Date: Thu Feb 13 2020 - 11:17:03 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.
Split time32.h into linux and common headers to make the latter suitable
for inclusion in the vDSO library.
