From c102f07667486dc4a6ae1e3fe7aa67135cb40e3e Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Sun, 27 Sep 2020 09:16:29 +0000 Subject: powerpc/vdso: Replace vdso_base by vdso All other architectures but s390 use a void pointer named 'vdso' to reference the VDSO mapping. In a following patch, the VDSO data page will be put in front of text, vdso_base will then not anymore point to VDSO text. To avoid confusion between vdso_base and VDSO text, rename vdso_base into vdso and make it a void __user *.
