From 06f99ac87ef3f1f706cd1eb794b16dfbfe60ee29 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 17 Oct 2007 18:04:40 +0200 Subject: [PATCH] x86: vdso put vars in rodata This adds a const to the definitions vvar.c makes, so that the vdso_* variables go into .rodata instead of .data. This is essentially a cosmetic change, just giving the section headers in the vDSO file more pleasing flags. These variables are read-only from the perspective of the vDSO itself and user mode, even though the contents of the DSO image were adjusted at boot.
