The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

|\| | | | | | | | | | | | | | | | | | | | | | | | | | | Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration.

| * be2net: bug fix on returning an invalid nic descriptorWei Yang2013-05-231-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In function be_get_nic_desc(), it will go through the descriptor array returned from f/w. By comparing the desc_type field, it determines whether there is a nic descriptor in the array or not. In the case of no nic descriptor, this function should return NULL. The code may return an invalide descriptor, when there is no nic descriptor in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case, even there is no nic descriptor, it will still return the lase descriptor since the i doesn't equal to MAX_RESOURCE_DESC. This patch fix this issue by returning the descriptor when find it and return NULL for other cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sets the coherent DMA mask to 64-bit after the be2net driver has been acknowledged that the system is 64-bit DMA capable. The coherent DMA mask is examined by the Intel IOMMU driver to determine whether to allow pass through context mapping for all devices. With this patch, the be2net driver combined with be2net compatible hardware provides comparable performance to the case where vt-d is disabled. The main use-case for this change is to decrease the time necessary to copy virtual machine memory during KVM live migration instantiations. This patch was tested on a system that enables the IOMMU in non-coherent mode. Two DMA remapper issues were encountered in the previous version and both patches have been committed. commit ea2447f700cab264019b52e2b417d689e052dcfd commit 2e12bc29fc5a12242d68e11875db3dd58efad9ff Signed-off-by: Craig Hada <craig.hada@hp.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

* | drivers:net: dma_alloc_coherent: use __GFP_ZERO instead of memset(, 0)Joe Perches2013-03-171-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reduce the number of calls required to alloc a zeroed block of memory. Trivially reduces overall object size. Other changes around these removals o Neaten call argument alignment o Remove an unnecessary OOM message after dma_alloc_coherent failure o Remove unnecessary gfp_t stack variable Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

* | drivers:net: Remove dma_alloc_coherent OOM messagesJoe Perches2013-03-153-15/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I believe these error messages are already logged on allocation failure by warn_alloc_failed and so get a dump_stack on OOM. Remove the unnecessary additional error logging. Around these deletions: o Alignment neatening. o Remove unnecessary casts of dma_alloc_coherent. o Hoist assigns from ifs.
