This patch is fatal for me in the downstream Raspberry Pi kernel - it locks up on boot even before the earlycon output is available. Hacking jump_label_init to skip the jump_entry for "crng_is_ready" allows it to boot, but is likely to have consequences further down the line.
Also, reading this a few times, I'm not 100% sure I understand what you did to hack around this and why that works. Think you could paste your hackpatch just out of interest to the discussion (but obviously not to be applied)?
