This got merged (commit d34b0733b452: "Revert "mm, page_alloc: only use per-cpu allocator for irq-safe requests"").
The other issue (caused by commit a499a5a14dbd: "sched/cputime: Increment kcpustat directly on irqtime account") is still open.
Frederic? Revert? But I guess it's something we can delay for backporting, it's presumably not possible to hit maliciously except on some fast local network attacker just causing an effective DoS.
