Subject: CVE request: kernel: NULL pointer dereference in sg_build_indirect()


Upstream proposed patch:

Triggered by firing up "xcdroast" to duplicate a CD.

  	for (i = 0; i < k; i++)
-		__free_pages(schp->pages[k], order);
+		__free_pages(schp->pages[i], order);

When the allocation in sg_build_indirect() fails, an oops can occur 
because of an obvious typo.

This was introduced by upstream commit 10db10d1 in v2.6.28-rc1.

Thanks, Eugene
