[PATCH] x86/x86_64: mark rodata section read-only: make some datastructures const
Mark some key kernel datastructures readonly. This patch was previously posted on Jun 28th but was back then not merged because nothing was enforcing rodata anyway.. well that changed now :) Patch by Christoph Lameter <christoph@lameter.com> and Dave Jones <davej@redhat.com> Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
