Regression detected on arm64 devices Hikey and Juno.

Here is the list of bad commit patches to be reverted.
git bisect found first bad commit as "3"
but reverting 3 patch failed.
so i have to revert all four patches and boot test and the boot PASS on hikey.

1)
Theodore Ts'o <tytso@xxxxxxx>
    random: add new ioctl RNDRESEEDCRNG
2)
Theodore Ts'o <tytso@xxxxxxx>
    random: crng_reseed() should lock the crng instance that it is modifying
3)
Theodore Ts'o <tytso@xxxxxxx>
    random: set up the NUMA crng instances after the CRNG is fully initialized
4)
Theodore Ts'o <tytso@xxxxxxx>
    random: fix crng_ready() test
