Eric Dumazet 40d0802b3e gro: __napi_gro_receive() optimizations
compare_ether_header() can have a special implementation on 64 bit
arches if CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is defined.

__napi_gro_receive() and vlan_gro_common() can avoid a conditional
branch to perform device match.

On x86_64, __napi_gro_receive() has now 38 instructions instead of 53

As gcc-4.4.3 still choose to not inline it, add inline keyword to this
performance critical function.

Giuseppe CAVALLARO ad01b7d480 stmmac: make ioaddr 'void __iomem *' rather than unsigned long
This avoids unnecessary casting and adds the ioaddr in the

this will, in the future, also be usable in AP

Johannes Berg 633adf1ad1 cfg80211: mark ieee80211_hdrlen const
This function analyses only its single, value-passed
argument, and has no side effects. Thus it can be
const, which makes mac80211 smaller, for example:

   text	   data	    bss	    dec	    hex	filename
 362518	  16720	    884	 380122	  5ccda	mac80211.ko (before)
 362358	  16720	    884	 379962	  5cc3a	mac80211.ko (after)

a 160 byte saving in text size, and an optimisation
because the function won't be called as often.

Simon Horman 1726442e11 net: increase the size of priv_flags and add IFF_OVS_DATAPATH
IFF_OVS_DATAPATH is a place-holder for the Open vSwitch datapath
which I am preparing to submit for merging.

As all 16 bits of priv_flags are already assigned flags, also increase
the size of priv_flags to 32 bits.

Unfortunately, by my calculations this increases the size of
struct net_device by 4 bytes on 32bit architectures and
8 bytes on 64 bit architectures. I couldn't see an obvious
way to avoid that.

David S. Miller 21dc330157 net: Rename skb_has_frags to skb_has_frag_list
SKBs can be "fragmented" in two ways, via a page array (called
skb_shinfo(skb)->frags[]) and via a list of SKBs (called
skb_shinfo(skb)->frag_list).

Since skb_has_frags() tests the latter, it's name is confusing
since it sounds more like it's testing the former.
