The pipapo set type uses a per-CPU scratch buffer which is protected
only by disabling BH. This series reworks the scratch buffer handlingand
adds nested-BH locking which is only used on PREEMPT_RT.
This series requires a reworked __local_lock_nested_bh() which can be
pulled in via
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git local-lock-for-net
It has been made available so that the netfilter changes can go
independantly of the TIP tree changes.

netfilter: nft_set_pipapo: Store real pointer, adjust later.
netfilter: nft_set_pipapo_avx2: Drop the comment regarding protection
netfilter: nft_set_pipapo: Use nested-BH locking for
