Subject: random: properly align get_random_int_hash

From: Eric Biggers <[email protected]>

commit b1132deac01c2332d234fa821a70022796b79182 upstream.

get_random_long() reads from the get_random_int_hash array using an unsigned long pointer. For this code to be guaranteed correct on all architectures, the array must be aligned to an unsigned long boundary.
