2013-09-03bonding: remove bond_vlan_used()Veaceslav Falico2-22/+2
We're using it currently to verify if we have vlans before getting the tag from the skb we're about to send. It's useless because the vlan_get_tag() verifies if the skb has the tag (and returns an error if not), and we can receive tagged skbs only if we *already* have vlans. Plus, the current RCUed implementation is kind of useless anyway - the we can remove the last vlan in the moment we return from the function. So remove the only usage of it and the whole function.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== Please accept this batch of updates intended for the 3.12 stream. For the mac80211 bits, Johannes says this: "This time I have various improvements all over the place: IBSS, mesh, testmode, AP client powersave handling, one of the rare rfkill patches and some code cleanup." Also for mac80211: "And I also have some more changes for -next, just a few small fixes and improvements, nothing really stands out." And for iwlwifi: "This time I have some powersave work (notably uAPSD support), CQM offloads, support for a new firmware API and various code cleanups." Regarding the Bluetooth bits, Gustavo says: "Patches to 3.12, here we have: * implementation of a proper tty_port for RFCOMM devices, this fixes some issues people were seeing lately in the kernel. * Add voice_setting option for SCO, it is used for SCO Codec selection * bugfixes, small improvements and clean ups" For the NFC bits, Samuel says: "With this one we have: - A few pn533 improvements and minor fixes. Testing our pn533 driver against Google's NCI stack triggered a few issues that we fixed now. We also added Tx fragmentation support to this driver. - More NFC secure element handling. We added a GET_SE netlink command for getting all the discovered secure elements, and we defined 2 additional secure element netlink event (transaction and connectivity). We also fixed a couple of typos and copy-paste bugs from the secure element handling code. - Firmware download support for the pn544 driver. This chipset can enter a special mode where it's waiting for firmware blobs to replace the already flashed one. We now support that mode." With repect to the ath tree, Kalle says: "New features in ath10k are rx/tx checsumming in hw and survey scan implemented by Michal. Also he made fixes to different areas of the driver, most notable being fixing the case when using two streams and reducing the number of interface combinations to avoid firmware crashes. Bartosz did a clean related to how we handle SoC power save in PCI layer. For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent crashes." I also pulled the wireless tree into wireless-next to support a request from Johannes. On top of all that, there are the usual sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k, and rt2x00 drivers all get some attention, as does the bcma bus and a few other random bits here and there. ==================== Signed-off-by: David S.

2013-09-03net: neighbour: Remove CONFIG_ARPDTim Gardner4-22/+0
This config option is superfluous in that it only guards a call to neigh_app_ns(). Enabling CONFIG_ARPD by default has no change in behavior. There will now be call to __neigh_notify() for each ARP resolution, which has no impact unless there is a user space daemon waiting to receive the notification, i.e., the case for which CONFIG_ARPD was designed anyways.

2013-09-03virtio-net: Set RXCSUM feature if GUEST_CSUM is availableThomas Huth1-0/+2
If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest does not have to calculate the checksums on all received packets. This is pretty much the same feature as RX checksum offloading on real network cards, so the virtio-net driver should report this by setting the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she can see whether the virtio-net interface has to calculate RX checksums or not.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: "A lot of activities on the cgroup front. Most changes aren't visible to userland at all at this point and are laying foundation for the planned unified hierarchy. - The biggest change is decoupling the lifetime management of css (cgroup_subsys_state) from that of cgroup's. Because controllers (cpu, memory, block and so on) will need to be dynamically enabled and disabled, css which is the association point between a cgroup and a controller may come and go dynamically across the lifetime of a cgroup. Till now, css's were created when the associated cgroup was created and stayed till the cgroup got destroyed. Assumptions around this tight coupling permeated through cgroup core and controllers. These assumptions are gradually removed, which consists bulk of patches, and css destruction path is completely decoupled from cgroup destruction path. Note that decoupling of creation path is relatively easy on top of these changes and the patchset is pending for the next window. - cgroup has its own event mechanism cgroup.event_control, which is only used by memcg. It is overly complex trying to achieve high flexibility whose benefits seem dubious at best.

Bjørn Mork says: ==================== net: set addr_assign_type when inheriting a dev_addr Copying the dev_addr from a parent device is an operation common to a number of drivers. The addr_assign_type should be updated accordingly, either by reusing the value from the source device or explicitly indicating that the address is stolen by setting addr_assign_type to NET_ADDR_STOLEN. This patch set adds a helper copying both the dev_addr and the addr_assign_type, and use this helper in drivers which don't currently set the addr_assign_type. Using NET_ADDR_STOLEN might be more appropriate in some of these cases. Please let me know, and I'll update the patch accordingly.

This was really only useful for TILE64 when we mapped the kernel data with small pages. Now we use a huge page and we really don't want to map different parts of the kernel data in different ways. We retain the __write_once name in case we want to bring it back to life at some point in the future. Note that this change uncovered a latent bug where the "smp_topology" variable happened to always be aligned mod 8 so we could store two "int" values at once, but when we eliminated __write_once it ended up only aligned mod 4. Fix with an explicit annotation. Signed-off-by: Chris Metcalf <[email protected]>
2013-09-03tile: remove support for TILE64Chris Metcalf28-1121/+34
This chip is no longer being actively developed for (it was superceded by the TILEPro64 in 2008), and in any case the existing compiler and toolchain in the community do not support it. It's unlikely that the kernel works with TILE64 at this point as the configuration has not been tested in years. The support is also awkward as it requires maintaining a significant number of ifdefs. So, just remove it altogether. Signed-off-by: Chris Metcalf <[email protected]>
2013-09-03tile: use asm-generic/bitops/builtin-*.hAkinobu Mita1-38/+3
The definisions of __ffs(), __fls(), and ffs() for tile are almost same as asm-generic/bitops-*.h. The only difference is that it is defined as __always_inline or inline. So this switches to use those headers. Signed-off-by: Akinobu Mita <[email protected]> Signed-off-by: Chris Metcalf <[email protected]> [moved #includes to end]

2013-09-03tile: simplify code referencing hypervisor API addressesChris Metcalf1-17/+8
There's no need to make up new ways of computing the addresses of the Tilera hypervisor APIs; just use the standard method of relying on the symbols to provide the addresses. Signed-off-by: Chris Metcalf <[email protected]>

2013-09-03tile: mark pcibios_init() as __initChris Metcalf2-2/+2
It was bombed away because it was previously marked as __devinit, but it should be an __init function. Signed-off-by: Chris Metcalf <[email protected]>
2013-09-03tile: check for correct compiler earlier in asm-offsets.cChris Metcalf1-8/+8
If we wait until after including a bunch of other files, we will have generated so much warning spew that it's hard to notice the error about using the wrong compiler. Signed-off-by: Chris Metcalf <[email protected]>

2013-09-03tile: add virt_to_kpte() API and clean up and document behaviorChris Metcalf6-11/+30
We use virt_to_pte(NULL, va) a lot, which isn't very obvious. I added virt_to_kpte(va) as a more obvious wrapper function, that also validates the va as being a kernel adddress. And, I fixed the semantics of virt_to_pte() so that we handle the pud and pmd the same way, and we now document the fact that we handle the final pte level differently.

2013-09-03tile: support FRAME_POINTERChris Metcalf4-9/+12
Allow enabling frame pointer support; this makes it easier to hook into the various kernel features that claim they require it without having to add Kconfig conditionals everywhere (a la mips, ppc, s390, and microblaze). When enabled, it basically eliminates leaf functions as such, and stops optimizing tail and sibling calls. It adds around 3% to the size of the kernel when enabled.

2013-09-03tile: support reporting Tilera hypervisor statisticsChris Metcalf2-3/+89

2013-09-03tilegx: provide kernel support for the tilegx UART shimChris Metcalf9-0/+768
The TILE-Gx chip includes an on-chip UART. This change adds support for using the UART from within the kernel. The UART shim has more functionality than is exposed here, but to keep the kernel code and binary simpler, this is a subset of the full API designed to enable a standard Linux tty serial driver only.

2013-09-03tile: parameterize VA and PA space more cleanlyChris Metcalf12-60/+51
The existing code relied on the hardware definition (<arch/chip.h>) to specify how much VA and PA space was available. It's convenient to allow customizing this for some configurations, so provide symbols MAX_PA_WIDTH and MAX_VA_WIDTH in <asm/page.h> that can be modified if desired. Additionally, move away from the MEM_XX_INTRPT nomenclature to define the start of various regions within the VA space. In fact the cleaner symbol is, for example, MEM_SV_START, to indicate the start of the area used for supervisor code; the actual address of the interrupt vectors is not as important, and can be changed if desired. As part of this change, convert from "intrpt1" nomenclature (which built in the old privilege-level 1 model) to a simple "intrpt". Also strip out some tilepro-specific code supporting modifying the PL the kernel could run at, since we don't actually support using different PLs in tilepro, only tilegx.
