Decreasing time for `rsa_init`

Dear Linux crypto folks,


Building CRYPTO_RSA not as module, but into the Linux kernel, `rsa_init()` takes 130 ms on an ASRock E350M1.

(Timings are shown by adding `initcall_debug` to Linux command line [1]. The times are visualized by `analyze_boot.py` from pm-graph [2] or `systemd-bootchart`.)

This is quite a lot of time compared to other modules, and I wonder if there are ways to decrease that time other than building it as a module, and not signing modules?


Kind regards,

Paul
