Linus Torvalds 57a269a1b1 mm: don't allow oversized kvmalloc() calls ... commit 7661809d49 upstream. 'kvmalloc()' is a convenience function for people who want to do a kmalloc() but fall back on vmalloc() if there aren't enough physically contiguous pages, or if the allocation is larger than what kmalloc() supports. However, let's make sure it doesn't get _too_ easy to do crazy things with it. In particular, don't allow big allocations that could be due to integer overflow or underflow. So make sure the allocation size fits in an 'int', to protect against trivial integer conversion issues.
