Following patch refactors GRE code into ip tunneling code and GRE specific code. Common tunneling code is moved to ip_tunnel module. ip_tunnel module is written as generic library which can be used by different tunneling implementations. ip_tunnel module contains following components: - packet xmit and rcv generic code. xmit flow looks like (gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out. - hash table of all devices. - lookup for tunnel devices. - control plane operations like device create, destroy, ioctl, netlink operations code. - registration for tunneling modules, like gre, ipip etc. - define single pcpu_tstats dev->tstats. - struct tnl_ptk_info added to pass parsed tunnel packet parameters. ipip.h header is renamed to ip_tunnel.h Signed-off-by: NPravin B Shelar <pshelar@nicira.com> Signed-off-by: NDavid S.

This patch is meant to be a follow-up for a patch originally submitted under the title "ioat: Do not enable DCA if tag map is invalid". It was brought to my attention that the preferred approach for BIOS workarounds is to set the taint flag for TAINT_FIRMWARE_WORKAROUND for systems that require BIOS workarounds. This change makes it so that the DCA workarounds for broken BIOSes will now use WARN_TAINT_ONCE(1, TAINT_FIRMWARE_WORKAROUND, ...) instead of just printing a message via dev_err.

As a result, all users of this mv643xx_eth driver are converted to register an "orion-mdio" platform_device. The mvmdio driver is also updated to support an interrupt line which reports SMI error/completion, and to allow traditionnal platform device registration instead of just device tree. David, I think it makes sense for you to merge all of this, since we do not want the architecture files to be desynchronized from the mv643xx_eth to avoid runtime breakage.

This patch converts the Marvell MV643XX ethernet driver to use the Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms registering the Marvell MV643XX ethernet driver are also updated to register a Marvell Orion MDIO driver. This driver voluntarily overlaps with the Marvell Ethernet shared registers because it will use a subset of this shared register (shared_base + 0x4 to shared_base + 0x84). The Ethernet driver is also updated to look up for a PHY device using the Orion MDIO bus driver. For ARM and PowerPC we register a single instance of the "mvmdio" driver in the system like it used to be done with the use of the "shared_smi" platform_data cookie on ARM. Note that it is safe to register the mvmdio driver only for the "ge00" instance of the driver because this "ge00" interface is guaranteed to always be explicitely registered by consumers of arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11) were all pointing their shared_smi to ge00. For PowerPC the in-tree Device Tree Source files mention only one MV643XX ethernet MAC instance so the MDIO bus driver is registered only when id == 0.

Use the device manager helper to ioremap() the base register cookie so we get automatic freeing upon error and removal.
