Date: Mon, 24 Sep 2007 04:04:58 -0700 (PDT) From: Roland McGrath <roland@...hat.com> To: Andi Kleen <ak@...e.de> Cc: Andrew Morton <akpm@...ux-foundation.org>, Linus Torvalds <torvalds@...ux-foundation.org>, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] x86_64 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.
