2012-05-02e1000e: fix .ndo_set_rx_mode for 82579Bruce Allan
Secondary unicast and multicast addresses are added to the Receive Address registers (RAR) for most parts supported by the driver. For 82579, there is only one actual RAR and a number of Shared Receive Address registers (SHRAR) that are shared among the driver and f/w which can be reserved and write-protected by the f/w. On this device, use the SHRARs that are not taken by f/w for the additional addresses. Add a MAC ops function pointer infrastructure (similar to other MAC operations in the driver) for setting RARs, introduce a new rar_set function for 82579 and convert the existing code that sets RARs on other devices to a generic rar_set function.

2012-05-02e1000e: workaround EEPROM configuration change on 82579Bruce Allan
An update to the EEPROM on 82579 will extend a delay in hardware to fix an issue with WoL not working after a G3->S5 transition which is unrelated to the driver. However, this extended delay conflicts with nominal operation of the device when it is initialized by the driver and after every reset of the hardware (i.e. the driver starts configuring the device before the hardware is done with it's own configuration work). The workaround for when the driver is in control of the device is to tell the hardware after every reset the configuration delay should be the original shorter one. Some pre-existing variables are renamed generically to be re-used with new register accesses.

2012-05-01cifs: don't cap ra_pages at the same level as default_backing_dev_infoJeff Layton
While testing, I've found that even when we are able to negotiate a much larger rsize with the server, on-the-wire reads often end up being capped at 128k because of ra_pages being capped at that level. Lifting this restriction gave almost a twofold increase in sequential read performance on my craptactular KVM test rig with a 1M rsize. I think this is safe since the actual ra_pages that the VM requests is run through max_sane_readahead() prior to submitting the I/O. Under memory pressure we should end up with large readahead requests being suppressed anyway. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2012-05-01USB: ehci-tegra: remove redundant gpio_set_valueStephen Warren
The immediately preceding gpio_direction_output() already set the value, so there's no need to repeat it. This also prevents gpio_set_value() from WARNing when the GPIO is sleepable (e.g. is on an I2C expander); the set direction API is always sleepable, but plain set_value isn't.

2012-05-01EHCI: update PM methods in ehci-tegra.cAlan Stern
This patch (as1547) rearranges the Power Management parts of the ehci-tegra driver to match the conventions used in other EHCI platform drivers. In particular, the controller should not be powered down by the root hub's suspend routine; the controller's power level should be managed by the controller's own PM methods. The end result of the patch is that the standard ehci_bus_suspend() and ehci_bus_resume() methods can be used instead of special-purpose routines. The driver now uses the standard dev_pm_ops methods instead of legacy power management. Since there is no supported wakeup mechanism for the controller, runtime suspend is forbidden by default (this can be overridden via sysfs, if desired). These adjustments are needed in order to make ehci-tegra compatible with recent changes to the USB core. The core now checks the root hub's status following bus suspend; if the controller is automatically powered down during bus suspend then the check will fail and the root hub will be resumed immediately. Doing the controller power-down in a separate method avoids this problem.

2012-05-01vt: Fix deadlock on scroll-lockAlan Cox
Fixing the locking accidentally replaced a race in the scroll lock handling with a deadlock. Turn it back into a race for now. The basic problem is that there are two paths into the tty stop/start helpers. One via the tty layer ^S/^Q handling where we need to take the kbd_event_lock and one via the special keyboard handler for fn_hold where we already hold it. Probably we need to split out into a separate LED lock but for now just go back to the race as it's a bit close to release.

2012-05-01sky2: fix receive length error in mixed non-VLAN/VLAN trafficstephen hemminger
Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older supported chips. Sometimes the VLAN bit is not set for valid VLAN packets and also sometimes the VLAN bit is set for non-VLAN packets that came after a VLAN packet. This results in a receive length error when VLAN hardware tagging is enabled. Fix: Variation on original fix proposed by Mirko. The VLAN information is decoded in the status loop, and can be applied to the received SKB there. This eliminates the need for the separate tag field in the interface data structure. The tag has to be copied and cleared if packet is copied. This version checked out with vlan and normal traffic. Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that is outside scope of this.

2012-05-01perf stat: Fix case where guest/host monitoring is not supported by kernelStephane Eranian
By default, perf stat sets exclude_guest = 1. But when you run perf on a kernel which does not support host/guest filtering, then you get an error saying the event in unsupported. This comes from the fact that when the perf_event_attr struct passed by the user is larger than the one known to the kernel there is safety check which ensures that all unknown bits are zero. But here, exclude_guest is 1 (part of the unknown bits) and thus the perf_event_open() syscall return EINVAL. To my surprise, running perf record on the same kernel did not exhibit the problem. The reason is that perf record handles the problem by catching the error and retrying with guest/host excludes set to zero. For some reason, this was not done with perf stat. This patch fixes this problem.

2012-04-30cxgb3: Don't call cxgb_vlan_mode until q locks are initializedRoland Dreier
The driver calls cxgb_vlan_mode() from init_one(). This calls into synchronize_rx(), which locks all the q locks, but the q locks are not initialized until cxgb_up() -> setup_sge_qsets(). So move the call to cxgb_vlan_mode() into cxgb_up(), after the call to setup_sge_qsets(). We also move the body of these functions up higher to avoid having to a forward declaration. This was found because of the lockdep warning: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

2012-04-30ixgbe: fix calling skb_put on nonlinear skb assertion bugYi Zou
With the support to bounce buffer added, the skb is coming as nonlinear in the case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack would take care of that. However, for target mode, we have to set the FC CRC and FC EOF field to allow the protocol stack to not drop the frame for the last data frame of that sequence. So fix this by linearizing the skb first before doing skb_put().

2012-04-30ixgbe: Fix a memory leak in IEEE DCBAlexander Duyck
The driver was freeing memory in shutdown instead of remove. As a result we were leaking memory if IEEE DCB was enabled and we loaded/unloaded the driver. This change moves the freeing of the memory into the remove routine where it belongs.
