2012-04-03ixgbe: driver fix for link flapMultanen, Eric W
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 Woodhouse
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 only annoyance is the RC6 enable, which really should have made -next, but since Ubuntu are shipping it I reckon its getting a good testing now by the time 3.4 comes out. 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.

For these users, we should therefore reject any userspace request to create a screen that requires a buffer larger than the framebuffer originally allocated.

2012-04-03APM: fix deadlock in APM_IOC_SUSPEND ioctlNeilBrown
I found the Xorg server on my ARM device stuck in the 'msleep()' loop in apm_ioctl. I suspect it had attempted suspend immediately after resuming and lost a race. During that msleep(10);, a new suspend cycle must have started and changed ->suspend_state to SUSPEND_PENDING, so it was never seen to be SUSPEND_DONE and the loop could never exited. It would have moved on to SUSPEND_ACKTO but never been able to reach SUSPEND_DONE. So change the loop to only run while SUSPEND_ACKED rather than until SUSPEND_DONE. This is much safer.

2012-04-02Merge branch 'drm-prime-dmabuf-initial' of ↵Linus Torvalds
git://people.freedesktop.org/~airlied/linux Pull dma-buf prime support from Dave Airlie: "This isn't a majorly urgent thing to have, but we'd like to set the stage for working on dma-buf support in the drm drivers for the next merge window, so I'd like to push in the initial submission now so people have something that we can build on top of. The code just introduces the user interface and internal helper functions for drivers to use. We have driver support under development for i915, nouveau, udl on x86 and exynos, omapdrm on arm, which we would be aiming for the next merge window." In the -rc1 announcement I asked for people who would use this to comment on it, and got severa "Yes please" from people for this and for HSI (that I merged earlier). So far crickets on pohmelfs and the DMA-mapping infrastructure. * 'drm-prime-dmabuf-initial' of git://people.freedesktop.org/~airlied/linux: drm: base prime/dma-buf support (v5)

Pull networking fixes from David Miller: 1) Provide device string properly for USB i2400m wimax devices, also don't OOPS when providing firmware string. From Phil Sutter. 2) Add support for sh_eth SH7734 chips, from Nobuhiro Iwamatsu. 3) Add another device ID to USB zaurus driver, from Guan Xin. 4) Loop index start in pool vector iterator is wrong causing MAC to not get configured in bnx2x driver, fix from Dmitry Kravkov. 5) EQL driver assumes HZ=100, fix from Eric Dumazet. 6) Now that skb_add_rx_frag() can specify the truesize increment separately, do so in f_phonet and cdc_phonet, also from Eric Dumazet. 7) virtio_net accidently uses net_ratelimit() not only on the kernel warning but also the statistic bump, fix from Rick Jones. 8) ip_route_input_mc() uses fixed init_net namespace, oops, use dev_net(dev) instead. Fix from Benjamin LaHaise. 9) dev_forward_skb() needs to clear the incoming interface index of the SKB so that it looks like a new incoming packet, also from Benjamin LaHaise. 10) iwlwifi mistakenly initializes a channel entry as 2GHZ instead of 5GHZ, fix from Stanislav Yakovlev. 11) Missing kmalloc() return value checks in orinoco, from Santosh Nayak. 12) ath9k doesn't check for HT capabilities in the right way, it is checking ht_supported instead of the ATH9K_HW_CAP_HT flag. Fix from Sujith Manoharan. 13) Fix x86 BPF JIT emission of 16-bit immediate field of AND instructions, from Feiran Zhuang. 14) Avoid infinite loop in GARP code when registering sysfs entries. From David Ward. 15) rose protocol uses memcpy instead of memcmp in a device address comparison, oops. Fix from Daniel Borkmann. 16) Fix build of lpc_eth due to dev_hw_addr_rancom() interface being renamed to eth_hw_addr_random(). From Roland Stigge. 17) Make ipv6 RTM_GETROUTE interpret RTA_IIF attribute the same way that ipv4 does. Fix from Shmulik Ladkani. 18) via-rhine has an inverted bit test, causing suspend/resume regressions. Fix from Andreas Mohr. 19) RIONET assumes 4K page size, fix from Akinobu Mita. 20) Initialization of imask register in sky2 is buggy, because bits are "or'd" into an uninitialized local variable. Fix from Lino Sanfilippo. 21) Fix FCOE checksum offload handling, from Yi Zou. 22) Fix VLAN processing regression in e1000, from Jiri Pirko. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (52 commits) sky2: dont overwrite settings for PHY Quick link tg3: Fix 5717 serdes powerdown problem net: usb: cdc_eem: fix mtu net: sh_eth: fix endian check for architecture independent usb/rtl8150 : Remove duplicated definitions rionet: fix page allocation order of rionet_active via-rhine: fix wait-bit inversion. ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4 net: lpc_eth: Fix rename of dev_hw_addr_random net/netfilter/nfnetlink_acct.c: use linux/atomic.h rose_dev: fix memcpy-bug in rose_set_mac_address Fix non TBI PHY access; a bad merge undid bug fix in a previous commit. net/garp: avoid infinite loop if attribute already exists x86 bpf_jit: fix a bug in emitting the 16-bit immediate operand of AND bonding: emit event when bonding changes MAC mac80211: fix oper channel timestamp updation ath9k: Use HW HT capabilites properly MAINTAINERS: adding maintainer for ipw2x00 net: orinoco: add error handling for failed kmalloc(). net/wireless: ipw2x00: fix a typo in wiphy struct initilization ...
