2013-05-09watchdog: Fix race condition in registration codeGuenter Roeck1-1/+2
A race condition exists when registering the first watchdog device. Sequence of events: - watchdog_register_device calls watchdog_dev_register - watchdog_dev_register creates the watchdog misc device by calling misc_register. At that time, the matching character device (/dev/watchdog0) does not yet exist, and old_wdd is not set either. - Userspace gets an event and opens /dev/watchdog - watchdog_open is called and sets wdd = old_wdd, which is still NULL, and tries to dereference it. This causes the kernel to panic. Seen with systemd trying to open /dev/watchdog immediately after it was created.

2013-05-08ARM: OMAP2+: omap_device: use late_initcall_syncKevin Hilman2-1/+2
If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled as a module, the kernel boot hangs early as the clocks for serial port are cut while earlyprintk still uses the port. The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.

2013-05-08ARM: OMAP: RX-51: change probe order of touchscreen and panel SPI devicesAaro Koskinen1-2/+2
Commit 9fdca9df (spi: omap2-mcspi: convert to module_platform_driver) broke the SPI display/panel driver probe on RX-51/N900. The exact cause is not fully understood, but it seems to be related to the probe order. SPI communication to the panel driver (spi1.2) fails unless the touchscreen (spi1.0) has been probed/initialized before. When the omap2-mcspi driver was converted to a platform driver, it resulted in that the devices are probed immediately after the board registers them in the order they are listed in the board file. Fix the issue by moving the touchscreen before the panel in the SPI device list. The patch fixes the following failure: [ 1.260955] acx565akm spi1.2: invalid display ID [ 1.265899] panel-acx565akm display0: acx_panel_probe panel detect error [ 1.273071] omapdss CORE error: driver probe failed: -19 Tested-by: Sebastian Reichel <[email protected]> Signed-off-by: Aaro Koskinen <[email protected]> Cc: Pali Rohár <[email protected]> Cc: Joni Lapilainen <[email protected]> Cc: Tomi Valkeinen <[email protected]> Cc: Felipe Balbi <[email protected]> Cc: [email protected] Signed-off-by: Tony Lindgren <[email protected]>

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.

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.

So, the resources required for all VFs must be provisioned by the PF driver *before* calling pci_enable_sriov(); else, VF probe will fail.
