I found this small problem in recent kernel

CC drivers/gpu/drm/drm_info.o drivers/gpu/drm/drm_info.c: In function ‘drm_vma_info’: drivers/gpu/drm/drm_info.c:277:19: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

I assume the problem is with high_memory volume variable, however I cannot find its definition.

I think problem was introduced in this commit

commit 01e2f533a234dc62d16c0d3d4fb9d71cf1ce50c3 Author: Kees Cook kees.cook@canonical.com Date: Fri Feb 11 19:29:44 2011 -0800

drm: do not leak kernel addresses via /proc/dri/*/vma

My system: gcc 4.6.2-4, 32-bit Intel Pentium M
