hwrng: core - Don't use a stack buffer in add_early_randomness()
hw_random carefully avoids using a stack buffer except in add_early_randomness(). This causes a crash in virtio_rng if CONFIG_VMAP_STACK=y. Reported-by: Matt Mullins <mmullins@mmlx.us> Tested-by: Matt Mullins <mmullins@mmlx.us> Fixes: d3cc7996473a ("hwrng: fetch randomness only after device init") Signed-off-by: Andy Lutomirski <luto@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
