After upgrading the kernel (from 3.17.8-gentoo-r1 to 3.18.7-gentoo) I ran the emerge @x11-module-rebuil and got the error.

Patch that fixes drm_mmap relocation.

I've had exactly the same issue after upgrading my kernel to 3.18.7.

The reason for this error is that in the kernel the declaration of the drm_mmap function was relocated from drmP.h to drm_legacy.h (see https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/include/drm/drmP.h?id=bfbf3c851ce53b914fe98d60ea3fe3fc1ab75b96).

The attached patch fixed this on my system by #including the drm_legacy.h header and changing the drm_mmap references in vboxvideo_drm.c to drm_legacy_mmap.

But I guess the fact that drm_mmap has been moved into a legacy header suggests that perhaps there's a better function that vboxvideo_drm.c should be using instead...?

This is probably a duplicate of bug 541050 and reportedly fixed in xf86-video-virtualbox-4.3.26
