2014-09-30net/mlx4_core: Deprecate error message at ConnectX-2 cards startup to debugJack Morgenstein
ConnectX2 HCAs have max_mtu=4k and max_vl=8 vls. However, if you specify a 4K mtu, the max_vl supported for 4K is 4 vls. The driver at startup attempts to set a 4K mtu using the max_vl value obtained from QUERY_PORT. Since the max_vl value is 8 vls (which is supported up to 2K mtu size), the first attempt to set the mtl/vl port value will fail, generating the following error message in the log: mlx4_core 0000:06:00.0: command 0xc failed: fw status = 0x40 The driver then tries again, using mtu=4k, vls=4, and this succeeds. Since we do not want to have this error message always displayed at driver start when there are ConnectX2 HCAs on the host, we deprecate the error message for this specific command/input_modifier/opcode_modifier/fw-status to be debug.

2014-09-30net/mlx4_core: New init and exit flow for mlx4_coreMajd Dibbiny
In the new flow, we separate the pci initialization and teardown from the initialization and teardown of the other resources. __mlx4_init_one handles the pci resources initialization. It then calls mlx4_load_one to initialize the remainder of the resources. When removing a device, mlx4_remove_one is invoked. However, now mlx4_remove_one calls mlx4_unload_one to free all the resources except the pci resources. When mlx4_unload_one returns, mlx4_remove_one then frees the pci resources. The above separation will allow us to implement 'reset flow' in the future. It will also enable more EQs for VFs and is a pre-step to the modern API to enable/disable SRIOV. Also added nvfs; an integer array of size MLX4_MAX_PORTS + 1; to the mlx4_dev struct. This new field is used to avoid parsing the num_vfs module parameter each time the mlx4_restart_one is called.

2014-09-30net/mlx4_core: Don't disable SRIOV if there are active VFsJack Morgenstein
When unloading the host driver while there are VFs active on VMs, the PF driver disabled sriov anyway, causing kernel crashes. We now leave SRIOV enabled, to avoid that. When the driver is reloaded, __mlx4_init_one is invoked on the PF. It now checks to see if SRIOV is already enabled on the PF -- and if so does not enable sriov again.

2014-09-30nfsd4: fix corruption of NFSv4 read dataJ. Bruce Fields
The calculation of page_ptr here is wrong in the case the read doesn't start at an offset that is a multiple of a page. The result is that nfs4svc_encode_compoundres sets rq_next_page to a value one too small, and then the loop in svc_free_res_pages may incorrectly fail to clear a page pointer in rq_respages[]. Pages left in rq_respages[] are available for the next rpc request to use, so xdr data may be written to that page, which may hold data still waiting to be transmitted to the client or data in the page cache. The observed result was silent data corruption seen on an NFSv4 client. We tag this as "fixing" 05638dc73af2 because that commit exposed this bug, though the incorrect calculation predates it.

Add a the common code used by all PXA variants. This is the first step in the transition from architecture defined clocks (in arch/arm/mach-pxa) towards clock framework. The goal is to have the same features (and not all the features) of the existing clocks, and enable the transition of PXA to device-tree. All PXA rely on a "CKEN" type clock, which : - has a gate (bit in CKEN register) - is generated from a PLL, generally divided - has an alternate low power clock Each variant will specialize the CKEN clock : - pxa25x have no low power clock - pxa27x in low power use always the 13 MHz ring oscillator - pxa3xx in low power have specific dividers for each clock The device-tree provides a list of CLK_* (ex: CLK_USB or CLK_I2C) to get a handle on the clock. While pxa-clock.h will describe all the clocks of all the variants, each variant will only use a subset of it.

2014-09-30PM / hibernate: Iterate over set bits instead of PFNs in swsusp_free()Joerg Roedel
The existing implementation of swsusp_free iterates over all pfns in the system and checks every bit in the two memory bitmaps. This doesn't scale very well with large numbers of pfns, especially when the bitmaps are not populated very densly. Change the algorithm to iterate over the set bits in the bitmaps instead to make it scale better in large memory configurations. Also add a memory_bm_clear_current() helper function that clears the bit for the last position returned from the memory bitmap. This new version adds a !NULL check for the memory bitmaps before they are walked. Not doing so causes a kernel crash when the bitmaps are NULL.

2014-09-30ACPI / sleep: Rework the handling of ACPI GPE wakeup from suspend-to-idleRafael J. Wysocki
The ACPI GPE wakeup from suspend-to-idle is currently based on using the IRQF_NO_SUSPEND flag for the ACPI SCI, but that is problematic for a couple of reasons. First, in principle the ACPI SCI may be shared and IRQF_NO_SUSPEND does not really work well with shared interrupts. Second, it may require the ACPI subsystem to special-case the handling of device notifications depending on whether or not they are received during suspend-to-idle in some places which would lead to fragile code. Finally, it's better the handle ACPI wakeup interrupts consistently with wakeup interrupts from other sources. For this reason, remove the IRQF_NO_SUSPEND flag from the ACPI SCI and use enable_irq_wake()/disable_irq_wake() with it instead, which requires two additional platform hooks to be added to struct platform_freeze_ops.

Since acpi_hw_enable_wakeup_gpe_block() is currently always called after disabling all GPEs, it can actually write zeros to all non-wakeup enable bits unconditionally. That will be useful going forward for disabling runtime GPEs and enabling wakeup GPEs in one go instead of doing that in two steps (disable runtime and enable wakeup) which in theory may lead to a loss of a wakeup event.

From the acpidump, it is found that there are more than one video output devices that have _BCM control method but the _DOD lists only one of them.

Also, we consider the broken _DOD case(reflected by the video->attached_count is 0) and do not change behaviour for those broken _DOD systems.

2014-09-30ipv6: remove rt6i_genidHannes Frederic Sowa
Eric Dumazet noticed that all no-nonexthop or no-gateway routes which are already marked DST_HOST (e.g. input routes routes) will always be invalidated during sk_dst_check. Thus per-socket dst caching absolutely had no effect and early demuxing had no effect. Thus this patch removes rt6i_genid: fn_sernum already gets modified during add operations, so we only must ensure we mutate fn_sernum during ipv6 address remove operations. This is a fairly cost extensive operations, but address removal should not happen that often. Also our mtu update functions do the same and we heard no complains so far. xfrm policy changes also cause a call into fib6_flush_trees. Also plug a hole in rt6_info (no cacheline changes). I verified via tracing that this change has effect.

2014-09-30ath9k_hw: fix PLL clock initialization for newer SoCFelix Fietkau
On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL register changed. This currently breaks at least 5/10 MHz operation. AR933x uses the old layout. It might also have been causing other stability issues because of the different location of the PLL_BYPASS bit which needs to be set during PLL clock initialization. This patch also removes more instances of hardcoded register values in favor of properly computed ones with the PLL_BYPASS bit added.

2014-09-30ath9k_hw: reduce ANI spur immunity setting on HT40 extension channelFelix Fietkau
The cycpwr_thr1 value needs to be lower on the extension channel than on the control channel, similar to how the register settings are programmed in the initvals. Also drop the unnecessary check for HT40 - this register can always be written. This patch has been reported to improve HT40 stability and throughput in some environments.
