[Regression] hangs caused by commit 3202fa62fb (slub: relocate freelist pointer to middle of object)

[Paul Menzel]

Dear Kees, dear Andrew,


No idea, if you are aware of it yet, but three people verified that 
commit 3202fa62fb (slub: relocate freelist pointer to middle of object) 
causes a regression on AMD hardware [1].

It’d be great, if you took a look, and advised if this commit (and 
follow-ups) should be reverted, until the issue is analyzed.


Kind regards,

Paul
