With merge help from Antonio Quartulli (batman-adv) and
Stephen Rothwell (drivers/net/usb/qmi_wwan.c).
The net/mac80211/mlme.c conflict seemed easy enough, accounting for a
conversion to some new tracing macros.

Using NLMSG_GOODSIZE results in multiple pages being used as
nlmsg_new() will automatically add the size of the netlink
header to the payload thus exceeding the page limit.
NLMSG_DEFAULT_SIZE takes this into account.

The qmi_wwan merge was trivial.
The caif_hsi.c, on the other hand, was not. It's a conflict between
1c385f1fdf ("caif-hsi: Replace platform
device with ops structure.") in the net-next tree and commit
39abbaef19 ("caif-hsi: Postpone init of
HIS until open()") in the net tree.
I did my best with that one and will ask Sjur to check it out.

The iwlwifi conflict was resolved by keeping the code added
in 'net' that turns off the buggy chip feature.
The MAINTAINERS conflict was merely overlapping changes, one
change updated all the wireless web site URLs and the other
changed some GIT trees to be Johannes's instead of John's.

nfc_llcp_general_bytes is defined in nfc/core.c as:

as in nfc/nfc.h:
nfc_llcp_general_bytes(struct nfc_dev *dev, u8 *gb_len), if CONFIG_NFC_LLCP
is not defined.
so we got some warnings,
