Perf of a boot of an aarch64 kernel, which
* debug enabled for regression testing,
* the v8.3-pauth instructions enabled,
* a local qemu patch to use aes128 for pauth.
I can dig up pointers if you want, but fairly niche.
Because of all the little debug-enabled functions, it meant we were doing a 1
block aes128 encrypt approximately every 40 guest instructions.
