Subject: [PATCH v5 0/3] vdso: Use only headers from the vdso/ namespace

The recent implementation of getrandom in the generic vdso library,
includes headers from outside of the vdso/ namespace.

The purpose of this series is to refactor the code to make sure
that the library uses only the allowed namespace.

Signed-off-by: Vincenzo Frascino <vincenzo.frascino@....com>

Changes:
--------
v5:
  - Fix an issue on s390 reported by kernel test robot.
v4:
  - Address review comments.
v3:
  - Discard vdso/mman.h changes in favor of [1].
  - Refactor vdso/page.h.
  - Add a fix to drm/intel_gt.
v2:
  - Added common PAGE_SIZE and PAGE_MASK definitions.
  - Added opencoded macros where not defined.
  - Dropped VDSO_PAGE_* redefinitions.
