Also in: linux-arm-kernel, linux-mips, lkml, loongarch
Subsystem: generic vdso library, library code, the rest · Maintainers: Andy Lutomirski, Thomas Gleixner, Vincenzo Frascino, Andrew Morton, Linus Torvalds

Revision v2 of 2 in this series.

Revisions (2)
  1. v1 [diff vs current]
  2. v2 current
vdso/datapage.h is useful without pulling in the architecture-specific
gettimeofday() helpers.

Move the include to the only users which needs it.
