powernv_rng_read: Oops: Kernel access of bad area, sig: 11 [#1]
Dear Linux folks,
After a long while, on the 8335-GCA POWER8 (raw) 0x4d0200 opal:skiboot-5.4.8-5787ad3 PowerNV, I built Linux from Linus’ master branch and rebooted via kexec.

- Three fixes to wire up our various RNGs earlier in boot so they're available for use in the initial seeding in
random_init().
I confirmed, that commit f3eac426657d (powerpc/powernv: wire up rng during setup_arch) [2] introduced the Oops.

- Three fixes to wire up our various RNGs earlier in boot so they're available for use in the initial seeding in
