2014-10-10macvlan: optimize the receive pathjbaron@akamai.com
The netif_rx() call on the fast path of macvlan_handle_frame() appears to be there to ensure that we properly throttle incoming packets. However, it would appear as though the proper throttling is already in place for all possible ingress paths, and that the call is redundant. If packets are arriving from the physical NIC, we've already throttled them by this point. Otherwise, if they are coming via macvlan_queue_xmit(), it calls either 'dev_forward_skb()', which ends up calling netif_rx_internal(), or else in the broadcast case, we are throttling via macvlan_broadcast_enqueue(). The test results below are from off the box to an lxc instance running macvlan. Once the tranactions/sec stop increasing, the cpu idle time has gone to 0. Results are from a quad core Intel E3-1270 V2@3.50GHz box with bnx2x 10G card. for i in {10,100,200,300,400,500}; do super_netperf $i -H $ip -t TCP_RR; done Average of 5 runs. trans/sec trans/sec (3.17-rc7-net-next) (3.17-rc7-net-next + this patch) ---------- ---------- 208101 211534 (+1.6%) 839493 850162 (+1.3%) 845071 844053 (-.12%) 816330 819623 (+.4%) 778700 789938 (+1.4%) 735984 754408 (+2.5%) Signed-off-by: Jason Baron <jbaron@akamai.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu Pull percpu updates from Tejun Heo: "A lot of activities on percpu front. Notable changes are... - percpu allocator now can take @gfp. If @gfp doesn't contain GFP_KERNEL, it tries to allocate from what's already available to the allocator and a work item tries to keep the reserve around certain level so that these atomic allocations usually succeed. This will replace the ad-hoc percpu memory pool used by blk-throttle and also be used by the planned blkcg support for writeback IOs. Please note that I noticed a bug in how @gfp is interpreted while preparing this pull request and applied the fix 6ae833c7fe0c ("percpu: fix how @gfp is interpreted by the percpu allocator") just now. - percpu_ref now uses longs for percpu and global counters instead of ints. It leads to more sparse packing of the percpu counters on 64bit machines but the overhead should be negligible and this allows using percpu_ref for refcnting pages and in-memory objects directly. - The switching between percpu and single counter modes of a percpu_ref is made independent of putting the base ref and a percpu_ref can now optionally be initialized in single or killed mode. This allows avoiding percpu shutdown latency for cases where the refcounted objects may be synchronously created and destroyed in rapid succession with only a fraction of them reaching fully operational status (SCSI probing does this when combined with blk-mq support). It's also planned to be used to implement forced single mode to detect underflow more timely for debugging. There's a separate branch percpu/for-3.18-consistent-ops which cleans up the duplicate percpu accessors. That branch causes a number of conflicts with s390 and other trees.

2014-10-10Thermal: move the KELVIN_TO_MILLICELSIUS macro to thermal.hAaron Lu
This macro can be used by other component so move it to a common header, but in a slightly different way: define two macros, one macro with an offset and the other doesn't. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-10-10ACPI / Fan: support INT3404 thermal deviceAaron Lu
INT3404 ACPI object follows the ACPI 5.0 fan object definition as described in section 11.3 of the ACPI 5.0 Specification. Thus we can reuse the ACPI fan driver for INT3404 ACPI object. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-10-10ACPI / Fan: add ACPI 4.0 style fan supportAaron Lu
This patch adds support for ACPI 4.0 style fan, lacking part is: no support for 'Low Speed Notification Support', 'Fine Grain Control' is not used yet. It's not clear what to do on suspend/resume callback for 4.0 style ACPI fan, so it does nothing for now. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-10-10ACPI / fan: convert to platform driverAaron Lu

2014-10-10ACPI / fan: use acpi_device_xxx_power instead of acpi_bus equivelantAaron Lu
When we have the acpi_device pointer, there is no need to pass the device's handle to the acpi_bus_xxx_power functions to get/set/update the device's power state, instead, use the acpi_device_xxx_power functions directly. To make this happen for fan module, export acpi_device_update_power. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-10-10ACPI / fan: remove no need check for device pointerAaron Lu
The device pointer will not be NULL in the PM callback and ACPI driver's add/remove callback, so checking NULL for them isn't necessary. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-10-10ACPI / fan: remove unused macroAaron Lu
The _COMPONENT, ACPI_MODULE_NAME(name) and ACPI_FAN_FILE_STATE are not used anywhere so remove them. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

Introduce int3400 thermal driver. And make INT3400 driver enumerate the other int340x thermal components shown in _ART/_TRT. Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2014-10-10ACPI: add ACPI_TYPE_LOCAL_REFERENCE support to acpi_extract_package()Zhang Rui
Add ACPI_TYPE_LOCAL_REFERENCE support to acpi_extract_package(), so that we can use this helper for more cases like _ART/_TRT. Signed-off-by: Zhang Rui <rui.zhang@intel.com>
