If anyone has any objections, please let me know. ------------------ From: "Luck, Tony" commit bd29e568a4cb6465f6e5ec7c1c1f3ae7d99cbec1 upstream. 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. Signed-off-by: Tony Luck Acked-by: H.
