While booting recent -next kernel on IBM Power server, I have observed lockups
either during boot or just after.

[ 3631.015775] watchdog: CPU 3 self-detected hard LOCKUP @ __update_freelist_slow+0x74/0x90

Sorry, the bug can be fixed by this patch from Vlastimil Babka:

https://lore.kernel.org/all/83ff4b9e-94f1-8b35-1233-3dd414ea4dfe@suse.cz/ (local)

The current -next should be fixed, the fix was folded to the preparatory
commit, which is now:

8a399e2f6003 ("slub: Keep track of whether slub is on the per-node partial
list")

Thanks!
