2012-04-05bonding: properly unset current_arp_slave on slave link upVeaceslav Falico1-1/+5
When a slave comes up, we're unsetting the current_arp_slave without removing active flags from it, which can lead to situations where we have more than one slave with active flags in active-backup mode. To avoid this situation we must remove the active flags from a slave before removing it as a current_arp_slave.

2012-04-04mlx4: allocate just enough pages instead of always 4 pagesThadeu Lima de Souza Cascardo1-2/+3
The driver uses a 2-order allocation, which is too much on architectures like ppc64, which has a 64KiB page. This particular allocation is used for large packet fragments that may have a size of 512, 1024, 4096 or fill the whole allocation. So, a minimum size of 16384 is good enough and will be the same size that is used in architectures of 4KiB sized pages. This will avoid allocation failures that we see when the system is under stress, but still has plenty of memory, like the one below. This will also allow us to set the interface MTU to higher values like 9000, which was not possible on ppc64 without this patch.

This patch fixes a link problem on BCM57712 + BCM8727 designs in which the TX laser is controller by GPIO, after 1.60.xx drivers were previously loaded. On these designs the TX_LASER is enabled by logic AND between the PHY (through MDIO), and the GPIO.

2012-04-04sky2: copy received packets on inefficient unaligned architecturestephen hemminger1-1/+12
Modified from original patch from Chris. The sky2 driver has to have 8 byte alignment of receive buffer on some chip versions. On architectures which don't support efficient unaligned access this doesn't work very well. The solution is to just copy all received packets which is what the driver already does for small packets. This allows the driver to be used on the Tilera TILEmpower-Gx, since the tile architecture doesn't currently handle kernel unaligned accesses, just userspace.

2012-04-04net/bonding: correctly proxy slave neigh param setup ndo functionShlomo Pongratz1-8/+43
The current implemenation was buggy for slaves who use ndo_neigh_setup, since the networking stack invokes the bonding device ndo entry (from neigh_params_alloc) before any devices are enslaved, and the bonding driver can't further delegate the call at that point in time. As a result when bonding IPoIB devices, the neigh_cleanup hasn't been called. Fix that by deferring the actual call into the slave ndo_neigh_setup from the time the bonding neigh_setup is called.

2012-04-03ixgbe: driver fix for link flapMultanen, Eric W1-84/+80
Fix up code so that changes in DCB settings are detected only when ixgbe_dcbnl_set_all is called. Previously, a series of 'change' commands followed by a call to ixgbe_dcbnl_set_all() would always be handled as a HW change - even if the net change was zero. This patch checks for this case of no actual change and skips going through the HW set process. Without this fix, the link could reset and result in a link flap. The core change in this patch is to check for changes in the ixgbe_copy_dcb_cfg() routine - and return a bitmask of detected changes. The other places where changes were detected previously can be removed.

2012-04-03ppp: Don't stop and restart queue on every TX packetDavid Woodhouse1-5/+9
For every transmitted packet, ppp_start_xmit() will stop the netdev queue and then, if appropriate, restart it. This causes the TX softirq to run, entirely gratuitously. This is "only" a waste of CPU time in the normal case, but it's actively harmful when the PPP device is a TEQL slave — the wakeup will cause the offending device to receive the next TX packet from the TEQL queue, when it *should* have gone to the next slave in the list. We end up seeing large bursts of packets on just *one* slave device, rather than using the full available bandwidth over all slaves. This patch fixes the problem by *not* unconditionally stopping the queue in ppp_start_xmit(). It adds a return value from ppp_xmit_process() which indicates whether the queue should be stopped or not. It *doesn't* remove the call to netif_wake_queue() from ppp_xmit_process(), because other code paths (especially from ppp_output_wakeup()) need it there and it's messy to push it out to the other callers to do it based on the return value. So we leave it in place — it's a no-op in the case where the queue wasn't stopped, so it's harmless in the TX path. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: David S.

The pull from Daniel contains his pull message to me: "A few patches for 3.4, major part is 3 regression fixes: - ppgtt broke hibernate on snb/ivb. Somehow our QA claims that it still works, which is why this has not been caught earlier. - ppgtt flails in combination with dmar. I kinda expected this one :( - fence handling bugfix for gen2/3. Iirc this one is about a year old, fix curtesy Chris Wilson. I've created an shockingly simple i-g-t test to catch this in the future." Wrt regressions I've just got a report that gmbus (newly enabled again in 3.4) is a bit noisy. I'm looking into this atm. Also included are the rc6 enable patches for snb from Eugeni. I wanted to include these in the main 3.4 pull but screwed it up. Please hit me. Imo these kind of patches really should go in before -rc1, but in thise case rc6 has brought us tons of press and guinea pigs^W^W testers and ubuntu is already running with it. So I estimate a pretty small chance for this to blow up. And some smaller things: - two minor locking snafus - server gt2 ivb pciid - 2 patches to sanitize the register state left behind by the bios some more - 2 new quirk entries - cs readback trick against missed IRQs from ivb also enabled on snb - sprite fix from Jesse" Let's see if the "enable RC6 on sandybridge" finally works and sticks.

mplayer -vo fbdev tries to create a screen that is twice as tall as the allocated framebuffer for "doublebuffering". By default, and all in-tree users, only sufficient memory is allocated and mapped to satisfy the smallest framebuffer and the virtual size is no larger than the actual.

Pull HSI (High Speed Synchronous Serial Interface) framework from Carlos Chinea: "The High Speed Synchronous Serial Interface (HSI) is a serial interface mainly used for connecting application engines (APE) with cellular modem engines (CMT) in cellular handsets. The framework is currently being used for some people and we would like to see it integrated into the kernel for 3.3. There is no HW controller drivers in this pull, but some people have already some of them pending which they would like to push as soon as this integrated. I am also working on the acceptance for an TI OMAP one, based on a compatible legacy version of the interface called SSI." Ok, so it didn't get into 3.3, but here it is pulled into 3.4.

Totally unexpected that this regressed. Luckily it sounds like we just need to have dmar disable on the igfx, not the entire system.

2012-04-02nouveau/bios: Fix tracking of BIOS image dataBenjamin Herrenschmidt1-1/+3
The code tries various methods for retreiving the BIOS data. However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best"). Fix that as well. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
