2012-04-15virtio-net: send gratuitous packets when neededJason Wang
As hypervior does not have the knowledge of guest network configuration, it's better to ask guest to send gratuitous packets when needed. This patch implements VIRTIO_NET_F_GUEST_ANNOUNCE feature: hypervisor would notice the guest when it thinks it's time for guest to announce the link presnece. Guest tests VIRTIO_NET_S_ANNOUNCE bit during config change interrupt and woule send gratuitous packets through netif_notify_peers() and ack the notification through ctrl vq. We need to make sure the atomicy of read and ack in guest otherwise we may ack more times than being notified. This is done through handling the whole config change interrupt in an non-reentrant workqueue. Signed-off-by: Jason Wang <jasowang@redhat.com> Acked-by: Michael S.

2012-04-14ARM: OMAP: clock: cleanup CPUfreq leftovers, fix build errorsKevin Hilman
Now that we have OPP layer, and OMAP CPUfreq driver is using it, we no longer need/use the clock framework code for filling up CPUfreq tables. Remove it. Removing this code also eliminates build errors when CPU_FREQ_TABLE support is not enabled.

2012-04-14tcp: bind() use stronger condition for bind_conflictAlex Copot
We must try harder to get unique (addr, port) pairs when doing port autoselection for sockets with SO_REUSEADDR option set. We achieve this by adding a relaxation parameter to inet_csk_bind_conflict. When 'relax' parameter is off we return a conflict whenever the current searched pair (addr, port) is not unique.

2012-04-14net/ethernet: ks8851_mll fix rx frame buffer overflowDavide Ciminaghi
At the beginning of ks_rcv(), a for loop retrieves the header information relevant to all the frames stored in the mac's internal buffers. The number of pending frames is stored as an 8 bits field in KS_RXFCTR. If interrupts are disabled long enough to allow for more than 32 frames to accumulate in the MAC's internal buffers, a buffer overflow occurs. This patch fixes the problem by making the driver's frame_head_info buffer big enough. Well actually, since the chip appears to have 12K of internal rx buffers and the shortest ethernet frame should be 64 bytes long, maybe the limit could be set to 12*1024/64 = 192 frames, but 255 should be safer.

2012-04-14e1000e: issues in Sx on 82577/8/9Bruce Allan
A workaround was previously put in the driver to reset the device when transitioning to Sx in order to activate the changed settings of the PHY OEM bits (Low Power Link Up, or LPLU, and GbE disable configuration) for 82577/8/9 devices. After further review, it was found such a reset can cause the 82579 to confuse which version of 82579 it actually is and broke LPLU on all 82577/8/9 devices. The workaround during an S0->Sx transition on 82579 (instead of resetting the PHY) is to restart auto-negotiation after the OEM bits are configured; the restart of auto-negotiation activates the new OEM bits as does the reset. With 82577/8, the reset is changed to a generic reset which fixes the LPLU bits getting set wrong.

2012-04-13cpufreq: OMAP: fix build errors: depends on ARCH_OMAP2PLUSKevin Hilman
The OMAP driver needs a 'depends on ARCH_OMAP2PLUS' since it only builds for OMAP2+ platforms. This 'depends on' was in the original patch from Russell King, but was erroneously removed by me when making this option user-selectable in commit b09db45c (cpufreq: OMAP driver depends CPUfreq tables.) This patch remedies that. Apologies to Russell King for breaking his originally working patch. Also, thanks to Grazvydas Ignotas for reporting the same problem.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes A few OMAP hwmod fixes against v3.4-rc2. One of them is a reversion of a previous v3.4-rc patch that caused some regressions, and upon further review, appears not to be necessary. The other two are fairly minor.
