Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Wed, 16 Nov 2011 16:41:02 -0800 random: Fix handing of arch_get_random_long in get_random_bytes() If there is an architecture-specific random number generator we use it to acquire randomness one "long" at a time. We should put these random words into consecutive words in the result buffer - not just overwrite the first word again and again.
