Subject: [PATCH v2 net-next 0/7] netfilter: updates for net-next

v2: drop patch 5, to be routed via net tree. No other changes.

Hi,

The following patchset contains Netfilter fixes for *net-next*:

1) prefer vmalloc_array in ebtables, from  Qianfeng Rong.
2) Use csum_replace4 instead of open-coding it, from Christophe Leroy.
3+4) Get rid of GFP_ATOMIC in transaction object allocations, those
     cause silly failures with large sets under memory pressure, from
     myself.
5) Remove test for AVX cpu feature in nftables pipapo set type,
   testing for AVX2 feature is sufficient.
6) Unexport a few function in nf_reject infra: no external callers.
7) Extend payload offset to u16, this was restricted to values <=255
   so far, from Fernando Fernandez Mancera.
