While booting Linux next 20211215 and next 20211217 on arm64 juno-r2 device the following kernel crash reported and several LTP syscalls test cases,

Only noticed on juno-r2 whereas dragonboard-410c and hikey-hi6220 tests pass.

Test case failure: add_key05.c:207: TBROK: Failed to open FILE '/proc/sys/kernel/keys/gc_delay' for writing: ENOENT (2) tst_taint.c:15: TBROK: Failed to open FILE '/proc/sys/kernel/tainted' for reading: ENOENT (2) tst_pid.c:43: TBROK: Failed to open FILE '/proc/sys/kernel/pid_max' for reading: ENOENT (2)
