net+crypto: Use vmalloc for zlib inflate buffers.
They are 64K and result in order-4 allocations, even with SLUB. Therefore, just like we always have for the deflate buffers, use vmalloc. Reported-by: Martin Jackson <mjackson220.list@gmail.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
