2013-05-08ARM: OMAP3: Beagle: Fix USB Host on beagle xM Ax/BxRoger Quadros1-3/+3
On Beagle xM Rev. Ax/Bx, the USB power enable GPIO logic is reversed when compared to other revisions i.e. it is active high instead of active low. Use the beagle_config.usb_pwr_level flag correctly so that the power regulator can be configured at runtime.

2013-05-08ARM: dts: OMAP4: Fix ethernet IRQ for OMAP4 boardsJon Hunter2-2/+2
Commit ff5c9059 (ARM: dts: OMAP3+: Correct gpio #interrupts-cells property) updated the number of interrupt cells required for configuring gpios as interrupts for other devices (such as ethernet controllers). This update allowed the interrupt type (edge, level, etc) to be configured via device-tree (as described in the Documentation/devicetree/bindings/gpio/gpio-omap.txt). This broke ethernet support on the OMAP4 SDP board that defines a gpio as the ethernet IRQ because the interrupt type (level, edge, etc) was not getting configured correctly. This board use the ks8851 ethernet chip which has an active low interrupt. Fix this by defining the gpio interrupt as active-low in the device-tree binding. Please note that the OMAP4-VAR-SOM also uses the same ethernet controller and it is expected it will have the same problem. So the same fix is also applied to this board.

2013-05-08mm/slab: Fix crash during slab initChris Mason1-10/+10
Commit 8a965b3baa89 ("mm, slab_common: Fix bootstrap creation of kmalloc caches") introduced a regression that caused us to crash early during boot. The commit was introducing ordering of slab creation, making sure two odd-sized slabs were created after specific powers of two sizes. But, if any of the power of two slabs were created earlier during boot, slabs at index 1 or 2 might not get created at all. This patch makes sure none of the slabs get skipped. Tony Lindgren bisected this down to the offending commit, which really helped because bisect kept bringing me to almost but not quite this one.

2013-05-08NFS4.1 Fix data server connection raceAndy Adamson2-2/+26
Unlike meta data server mounts which support multiple mount points to the same server via struct nfs_server, data servers support a single connection. Concurrent calls to setup the data server connection can race where the first call allocates the nfs_client struct, and before the cache struct nfs_client pointer can be set, a second call also tries to setup the connection, finds the already allocated nfs_client, bumps the reference count, re-initializes the session,etc. This results in a hanging data server session after umount.

2013-05-08sierra_net: keep status interrupt URB activeDan Williams1-7/+31
The driver and firmware sync up through SYNC messages, and the firmware's affirmative reply to these SYNC messages appears to be the "Reset" indication received via the status interrupt endpoint. Thus the driver needs the status interrupt endpoint always active so that the Reset indication can be received even if the netdev is closed, which is the case right after device insertion. If the Reset indication is not received by the driver, it continues sending SYNC messages to the firmware, which crashes about 10 seconds later and the device stops responding.

2013-05-08usbnet: allow status interrupt URB to always be activeDan Williams2-6/+76
Some drivers (sierra_net) need the status interrupt URB active even when the device is closed, because they receive custom indications from firmware. Add functions to refcount the status interrupt URB submit/kill operation so that sub-drivers and the generic driver don't fight over whether the status interrupt URB is active or not. A sub-driver can call usbnet_status_start() at any time, but the URB is only submitted the first time the function is called. Likewise, when the sub-driver is done with the URB, it calls usbnet_status_stop() but the URB is only killed when all users have stopped it. The URB is still killed and re-submitted for suspend/resume, as before, with the same refcount it had at suspend.

The EQ may get full resulting in a HW error. Fix this by not re-arming the CQ while notifying a valid completion.

After build_free_nids() searches free nid candidates from nat pages and current journal blocks, it checks all the candidates if they are allocated so that the nat cache has its nid with an allocated block address. In this procedure, previously we used list_for_each_entry_safe(fnid, next_fnid, &nm_i->free_nid_list, list). But, this is not covered by free_nid_list_lock, resulting in null pointer bug.
