[PATCH v3 0/2] vdso: Use only headers from the vdso/ namespace

From: Vincenzo Frascino
Date: Thu Oct 03 2024 - 11:29:36 EST


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

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

The series has been rebased on [1] to simplify the testing.

Changes:
--------
v3:
- Discard vdso/mman.h changes in favor of [2].
- 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.
