2011-10-18drm/exynos: fixed page flip bug.Inki Dae
in case of using two drivers such as fimd and hdmi controller that they have their own hardware interrupt, drm framework doesn't provide pipe number corresponding to it. so the pipe should be set to event's from specific crtc.

2011-10-18md: clear In_sync bit on devices added to an active array.NeilBrown
When we add a device to an active array it can be meaningful to set the 'insync' flag. This indicates that the device is in-sync with the array except for locations recorded in the bitmap. A bitmap-based recovery can then bring it completely in-sync. Internally we move that flag to 'saved_raid_disk' but forgot to clear In_sync like we do in add_new_disk. So clear In_sync after moving its value to saved_raid_disk. Reported-by: Andrei Warkentin <andreiw@vmware.com> Signed-off-by: NeilBrown <neilb@suse.de>

2011-10-17ehea: Allocate large enough skbs to avoid partial cacheline DMA writesAnton Blanchard
The ehea adapter has a mode where it will avoid partial cacheline DMA writes on receive by always padding packets to fall on a cacheline boundary. Unfortunately we currently aren't allocating enough space for a full ethernet MTU packet to be rounded up, so this optimisation doesn't hit. It's unfortunate that the next largest packet size exposed by the hypervisor interface is 2kB, meaning our skb allocation comes out of a 4kB SLAB. However the performance increase due to this optimisation is quite large and my TCP stream numbers increase from 900MB to 1000MB/sec.

We can also remove pr->queue_stopped and just check the queue status directly. - Print all 16 queues in the ethtool stats.

2011-10-17staging: vme: get rid of struct vme_device_id and slotsManohar Vanga
Previously, the device-driver matching mechanism depended on the vme_device_id structure due to the need for a bind table per driver. This method of matching is no longer used so this patch merges the fields of struct vme_device_id into struct vme_dev. Since this also renders the slot field meaningless, it has also been removed in this patch.

2011-10-17staging: vme: make match() driver specific to improve non-VME64x supportManohar Vanga
For jumper based boards (non VME64x), there is no mechanism for detecting the card that is plugged into a specific slot. This leads to issues in non-autodiscovery crates/cards when a card is plugged into a slot that is "claimed" by a different driver. In reality, there is no problem, but the driver rejects such a configuration due to its dependence on the concept of slots. This patch makes the concept of slots less critical and pushes the driver match() to individual drivers (similar to what happens in the ISA bus in driver/base/isa.c). This allows drivers to register the number of devices that they expect without any restrictions. Devices in this new model are now formatted as $driver_name-$bus_id.$device_id (as compared to the earlier vme-$bus_id.$slot_number). This model also makes the device model more logical as devices are only registered when they actually exist whereas earlier, a set of devices were being created automatically regardless of them actually being there. Another change introduced in this patch is that devices are now created within the VME driver structure rather than in the VME bridge structure. This way, things don't go haywire if the bridge driver is removed while a driver is using it.

2011-10-17staging: vme: add struct vme_dev for VME devicesManohar Vanga
Instead of using a vanilla 'struct device' for VME devices, add new 'struct vme_dev'. Modifications have been made to the VME framework API as well as all in-tree VME drivers. The new vme_dev structure has the following advantages from the current model used by the driver: * Driver functions (probe, remove) now receive a VME device instead of a pointer to the bridge device (cleaner design) * It's easier to differenciate API calls as bridge-based or device-based (ie. cleaner interface).
