In the Linux kernel, the following vulnerability has been resolved:
drm/i915/selftests: fix subtraction overflow bug
On some machines hole_end can be small enough to cause subtraction
overflow. On the other side (addr + 2 * min_alignment) can overflow
in case of mock tests. This patch should handle both cases.
