2013-05-27fec: Handle the regulator in suspend/resumeFabio Estevam1-0/+10
In order to save power, let's disable the regulator in the suspend function and enable it in resume. Tested on a mx28evk board. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-05-27fec: Remove irqs firstFabio Estevam1-5/+5
During probe the clocks are enabled prior than the acquiring the interrupts. In the remove function we need to do the opposite: first remove the interrupts and then disable the clocks. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-05-27fec: Disable the PHY regulator on error and removalFabio Estevam1-0/+6
In the case of error during probe, disable the PHY regulator. Do the same in fec_drv_remove(). Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-05-27fec: Invert the order of error path sequenceFabio Estevam1-2/+2
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. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-05-27fec: Place the phy regulator in the private structureFabio Estevam2-4/+4
Instead of using a local reg_phy structure, let's put it inside the private structure, so that we are able to have access to the regulator structure even when we are outside fec_probe(). This is in preparation for controlling the FEC PHY regulator in the suspend and resume functions. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S.

2013-05-27bnx2x: Change to D3hot only on removalYuval Mintz2-10/+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).

2013-05-27bnx2x: Implement PCI shutdownYuval Mintz1-12/+59
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.

Commit 0eb43b4bb081a1a22574daab9c05286a600dd7fe "bnx2x, bnx2fc: Use per port max exchange resources" has changed the number of available FCoE exchanges, even in scenarios when some of the functions has no FCoE support; This needlessly degraded the available resources. Remedy this by calculating the maximal number of functions that may actually utilize said connection.

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device.

2013-05-25net: ipv6: Add IPv6 support to the ping socket.Lorenzo Colitti9-171/+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.

2013-05-24GFS2: Use single-block reservations for directoriesBob Peterson1-2/+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.

2013-05-24powerpc/pseries: Make 32-bit MSI quirk work on systems lacking firmware supportBrian King1-3/+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.

Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway.
