The pktcdvd driver uses proper locking and does not need the BKL in the ioctl and llseek functions of the character device, so kill both. Moving the compat_ioctl handling from common code into the driver itself fixes build problems when CONFIG_BLOCK is disabled. Acked-by:

If dentry found stale happens to be a root of disconnected tree, we can't d_drop() it; its d_hash is actually part of s_anon and d_drop() would simply hide it from shrink_dcache_for_umount(), leading to all sorts of fun, including busy inodes on umount and oopsen after that. Bug had been there since at least 2006 (commit c636eb already has it), so it's definitely -stable fodder. Signed-off-by:

ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483 and 03db42ad and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by:

Firmware changed the way it represents memory and cpu affinity on POWER7. Unfortunately the old method now caps the topology to work around issues with legacy operating systems. For Linux to get the correct topology we need to use the new form 1 affinity information. We set the form 1 field in the client architecture, and if we see "1" in the ibm,associativity-form property firmware supports form 1 affinity and we should look at the first field in the ibm,associativity-reference-points array. If not we use the second field as we always have. Signed-off-by:

Re-submitted based on comments from netdev community. Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system. Signed-off-by:

Autosuspend works until you bring the wwan interface up, then the device does not enter autosuspend anymore. The following patch fixes the problem by setting the .manage_power field in the mbm_info struct to the same as in the cdc_info struct (cdc_manager_power). Signed-off-by:

When gracefully stopping the controller, the driver was continuing if *either* RX or TX had stopped. We need to wait for both, or the controller could get into an invalid state. Signed-off-by:

The request_key() system call and request_key_and_link() should make a link from an existing key to the destination keyring (if supplied), not just from a new key to the destination keyring. This can be tested by: ring=`keyctl newring fred @s` keyctl request2 user debug:a a keyctl request user debug:a $ring keyctl list $ring If it says: keyring is empty then it didn't work. If it shows something like: 1 key in keyring: 1070462727: --alswrv 0 0 user: debug:a then it did. request_key() system call is meant to recursively search all your keyrings for the key you desire, and, optionally, if it doesn't exist, call out to userspace to create one for you. If request_key() finds or creates a key, it should, optionally, create a link to that key from the destination keyring specified. Therefore, if, after a successful call to request_key() with a desination keyring specified, you see the destination keyring empty, the code didn't work correctly. If you see the found key in the keyring, then it did - which is what the patch is required for. Signed-off-by:

Bill Gatliff reported the following bug when using the irq_chip facility of the pca953x driver on a PPC platform: BUG: scheduling while atomic: insmod/1530/0x00000002 He traced it back to an i2c transaction in pca953x_irq_set_type(), which can be called with interrupt disabled (from __setup_irq()). As the i2c controller can sleep while sending a message, this qualifies as a bad idea. This patch moves the i2c transaction to pca953x_irq_bus_sync_unlock(), where it is actually safe to send an i2c message. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:
