[ Upstream commit 303fd3e1c771077e32e96e5788817f025f0067e2 ]
The signed long type used for printing the number of bytes processed in tcrypt benchmarks limits the range to -/+ 2 GiB, which is not sufficient to cover the performance of common accelerated ciphers such as AES-NI when benchmarked with sec=1. So switch to u64 instead.
While at it, fix up a missing printk->pr_cont conversion in the AEAD benchmark.
