* net: ethernet: remove unnecessary platform_set_drvdata()Jingoo Han2013-05-2837-61/+0
| | | | | | | | | | | | | | | | The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

| | | | | | | | | | | | | | | | | | | | | | | | Currently when fec_enet_init fails it jumps to 'failed_init' error path, which will attemp to free the interrupts. This is wrong because at this point the interrupts have not even been acquired. Swap failed_init/failed_irq to fix the error path.

* bnx2x: Change to D3hot only on removalYuval Mintz2013-05-282-10/+24
| | | | | | | | | | | | | | | | This changes the PCI power management scheme of the bnx2x driver to be similar to those of most network drivers - the driver will now changes the power state into D3hot whenever the driver will be removed, instead of whenever an interface is unloaded. This change enables the driver to access its eeprom via ethtool callbacks even when interfaces are unloaded (such access requires the function to be in D0active).

| | | | | | | | | | | | | | | | Implement the PCI shutdown callback to support un-orderly shutdown, i.e., shutdowns in which the remove callback will not be called. Due to the lack of this functionality, when an un-orderly shutdown occurred, it was possible for wake-on-lan to remain disabled. This is now fixed as the callback introduces the correct place in which `system_state' can be queried and wake-on-lan be configured accordingly.

* net: ipv6: Add IPv6 support to the ping socket.Lorenzo Colitti2013-05-269-171/+698
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to send ICMPv6 echo requests without a raw socket. The equivalent ability for ICMPv4 was added in 2011. Instead of having separate code paths for IPv4 and IPv6, make most of the code in net/ipv4/ping.c dual-stack and only add a few IPv6-specific bits (like the protocol definition) to a new net/ipv6/ping.c. Hopefully this will reduce divergence and/or duplication of bugs in the future. Caveats: - Setting options via ancillary data (e.g., using IPV6_PKTINFO to specify the outgoing interface) is not yet supported. - There are no separate security settings for IPv4 and IPv6; everything is controlled by /proc/net/ipv4/ping_group_range. - The proc interface does not yet display IPv6 ping sockets properly. Tested with a patched copy of ping6 and using raw socket calls. Compiles and works with all of CONFIG_IPV6={n,m,y}. Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

| | * GFS2: Use single-block reservations for directoriesBob Peterson2013-05-241-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the multi-block allocation code, such that directory inodes only get a single block reserved in the bitmap. That way, the bitmaps are more tightly packed together, and there are fewer spans of free blocks for in-use block reservations. This means it takes less time to find a free span of blocks in the bitmap, which speeds things up. This increases the performance of some workloads by almost 2X. In Nate's mockup.py script (which does (1) create dir, (2) create dir in dir, (3) create file in that dir) the test executes in 23 steps rather than 43 steps, a 47% performance improvement.

| | * | powerpc/pseries: Make 32-bit MSI quirk work on systems lacking firmware supportBrian King2013-05-241-3/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent commit e61133dda480062d221f09e4fc18f66763f8ecd0 added support for a new firmware feature to force an adapter to use 32 bit MSIs. However, this firmware is not available for all systems. The hack below allows devices needing 32 bit MSIs to work on these systems as well. It is careful to only enable this on Gen2 slots, which should limit this to configurations where this hack is needed and tested to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The zImage.epapr wrapper allows to use zImages when booting via a flat device-tree which can be used on powernv. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
