From dd937454d905fad9fcbeccd35ecfc8c3c096fe76 Mon Sep 17 00:00:00 2001 From: Thomas Weißschuh Date: Thu, 10 Oct 2024 09:01:13 +0200 Subject: x86/vdso: Use __arch_get_vdso_data() to access vdso data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The implementation details of the vdso_data access will change. Prepare for that by using the existing helper function.
