Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Conflicts:
	drivers/net/ethernet/emulex/benet/be.h
	drivers/net/usb/qmi_wwan.c
	drivers/net/wireless/brcm80211/brcmfmac/dhd_bus.h
	include/net/netfilter/nf_conntrack_synproxy.h
	include/net/secure_seq.h

The conflicts are of two varieties:

1) Conflicts with Joe Perches's 'extern' removal from header file
   function declarations.  Usually it's an argument signature change
   or a function being added/removed.  The resolutions are trivial.

2) Some overlapping changes in qmi_wwan.c and be.h, one commit adds
   a new value, another changes an existing value.  That sort of
   thing.

Embedded device command line partition
Embedded device command line partition parsing
=====================================================================
Read block device partition table from command line.
The partition used for fixed block device (eMMC) embedded device.
It is no MBR, save storage space. Bootloader can be easily accessed
Support for reading the block device partition table from the command line.
It is typically used for fixed block (eMMC) embedded devices.
It has no MBR, so saves storage space. Bootloader can be easily accessed
by absolute address of data on the block device.
Users can easily change the partition.
