v1 -> v2: - Use printk_once. Because the serial console is so slow, printing the message multiple times consumed about 6ms extra later on in the boot. Printing it only once is both neater and avoids this extra overhead. Rich. - - - I'm trying to reduce the time taken in the kernel in initcalls, with my aim being to reduce the current ~700ms spent in initcalls before userspace, down to something like 100ms. All times on my Broadwell-U laptop, under virtualization. The purpose of this is to be able to launch VMs around containers with minimal overhead, like Intel Clear Containers, but using standard distro kernels and qemu. Currently the kernel spends 28ms (on my laptop) running crypto algorithm self-tests. Although it's possibe to disable these at compile time, Fedora kernel maintainers want to maintain a single kernel image for all uses. So this commit adds a runtime flag which callers can set to skip the self-tests in the fast container/virtualization case. -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
