Cover letter [PATCH v2 0/2] crypto: xor - defer and optimize boot time benchmark

Doug reports [0] that the XOR boot time benchmark takes more time than necessary, and runs at a time when there is little room for other boot time tasks to run concurrently.

Let's fix this by #1 deferring the benchmark, and #2 uses a faster implementation.

Changes since v2:
- incorporate Doug's review feedback re coarse clocks and the use of pr_info
- add Doug's ack to #1
