2014-08-25bna: Support TSO and partial checksum with non-accelerated vlans.Vlad Yasevich1-3/+4
This device claims TSO and checksum support for vlans. It also allows a user to control vlan acceleration offloading. As such, it is possible to turn off vlan acceleration and configure a vlan which will continue to support TSO. In such situation the packet passed down the the device will contain a vlan header and skb->protocol will be set to ETH_P_8021Q. The device assumes that skb->protocol contains network protocol value and uses that value to set up TSO information. This results in corrupted frames sent on the wire. This patch extract the protocol value correctly and corrects TSO and checksums for non-accelerated traffic.

2014-08-25trace: Fix epoll hang when we race with new entriesJosef Bacik1-1/+15
Epoll on trace_pipe can sometimes hang in a weird case. If the ring buffer is empty when we set waiters_pending but an event shows up exactly at that moment we can miss being woken up by the ring buffers irq work. Since ring_buffer_empty() is inherently racey we will sometimes think that the buffer is not empty. So we don't get woken up and we don't think there are any events even though there were some ready when we added the watch, which makes us hang. This patch fixes this by making sure that we are actually on the wait list before we set waiters_pending, and add a memory barrier to make sure ring_buffer_empty() is going to be correct.

previous QR_EC There is platform refusing to respond QR_EC when SCI_EVT isn't set which is Acer Aspire V5-573G. By disallowing QR_EC to be issued before the previous one has been completed we are able to reduce the possibilities to trigger issues on such platforms. Note that this fix can only reduce the occurrence rate of this issue, but this issue may still occur when such a platform doesn't clear SCI_EVT before or immediately after completing the previous QR_EC transaction. This patch cannot fix the CLEAR_ON_RESUME quirk which also relies on the assumption that the platforms are able to respond even when SCI_EVT isn't set. But this patch is still useful as it can help to reduce the number of scheduled QR_EC work items.

2014-08-26ACPI / EC: Add support to disallow QR_EC to be issued when SCI_EVT isn't setLv Zheng1-1/+16
There is a platform refusing to respond QR_EC when SCI_EVT isn't set (Acer Aspire V5-573G). Currently, we rely on the behaviour that the EC firmware can respond something (for example, 0x00 to indicate "no outstanding events") to QR_EC even when SCI_EVT is not set, but the reporter has complained about AC/battery pluging/unpluging and video brightness change delay on that platform. This is because the work item that has issued QR_EC has to wait until timeout in this case, and the _Qxx method evaluation work item queued after QR_EC one is delayed. It sounds reasonable to fix this issue by: 1. Implementing SCI_EVT sanity check before issuing QR_EC in the EC driver's main state machine. 2. Moving QR_EC issuing out of the work queue used by _Qxx evaluation to a seperate IRQ handling thread. This patch fixes this issue using solution 1. By disallowing QR_EC to be issued when SCI_EVT isn't set, we are able to handle such platform in the EC driver's main state machine. This patch enhances the state machine in this way to survive with such malfunctioning EC firmware. Note that this patch can also fix CLEAR_ON_RESUME quirk which also relies on the assumption that the platforms are able to respond even when SCI_EVT isn't set.

2014-08-26ACPI: Run fixed event device notifications in process contextLan Tianyu1-5/+10
Currently, notify callbacks for fixed button events are run from interrupt context. That is not necessary and after commit 0bf6368ee8f2 (ACPI / button: Add ACPI Button event via netlink routine) it causes netlink routines to be called from interrupt context which is not correct. Also, that is different from non-fixed device events (including non-fixed button events) whose notify callbacks are all executed from process context. For the above reasons, make fixed button device notify callbacks run in process context which will avoid the deadlock when using netlink to report button events to user space.

2014-08-26ACPI / scan: Allow ACPI drivers to bind to PNP device objectsRafael J. Wysocki1-1/+1
We generally don't allow ACPI drivers to bind to ACPI device objects that companion "physical" device objects are created for to avoid situations in which two different drivers may attempt to handle one device at the same time. Recent ACPI device enumeration rework extended that approach to ACPI PNP devices by starting to use a scan handler for enumerating them. However, we previously allowed ACPI drivers to bind to ACPI device objects with existing PNP device companions and changing that led to functional regressions on some systems. For this reason, add a special check for PNP devices in acpi_device_probe() so that ACPI drivers can bind to ACPI device objects having existing PNP device companions as before.

2014-08-25ARM: OMAP2+: hwmod: Rearm wake-up interrupts for DT when MUSB is idledTony Lindgren1-0/+4
Looks like MUSB cable removal can cause wake-up interrupts to stop working for device tree based booting at least for UART3 even as nothing is dynamically remuxed. This can be fixed by calling reconfigure_io_chain() for device tree based booting in hwmod code. Note that we already do that for legacy booting if the legacy mux is configured. My guess is that this is related to UART3 and MUSB ULPI hsusb0_data0 and hsusb0_data1 support for Carkit mode that somehow affect the configured IO chain for UART3 and require rearming the wake-up interrupts. In general, for device tree based booting, pinctrl-single calls the rearm hook that in turn calls reconfigure_io_chain so calling reconfigure_io_chain should not be needed from the hwmod code for other events. So let's limit the hwmod rearming of iochain only to HWMOD_FORCE_MSTANDBY where MUSB is currently the only user of it. If we see other devices needing similar changes we can add more checks for it.

When an alias for a clock already exists the warning is printed. For every module with a main_clk defined, a clk alias for fck is added. There are some components that have the same main_clk defined, so this is a really normal situation. For example the am33xx edma device has 4 components using the same main clock. So there are three warnings in the boot log for this already existing clock alias: platform 49000000.edma: alias fck already exists platform 49000000.edma: alias fck already exists platform 49000000.edma: alias fck already exists As this is only interesting for developers, this patch changes the message to a debug message.

2014-08-25mtd: nand: omap: Fix 1-bit Hamming code scheme, omap_calculate_ecc()Roger Quadros1-1/+1
commit 65b97cf6b8de introduced in v3.7 caused a regression by using a reversed CS_MASK thus causing omap_calculate_ecc to always fail. As the NAND base driver never checks for .calculate()'s return value, the zeroed ECC values are used as is without showing any error to the user. However, this won't work and the NAND device won't be guarded by any error code. Fix the issue by using the correct mask. Code was tested on omap3beagle using the following procedure - flash the primary bootloader (MLO) from the kernel to the first NAND partition using nandwrite. - boot the board from NAND. This utilizes OMAP ROM loader that relies on 1-bit Hamming code ECC.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt: "The rewrite of the ftrace code that makes it possible to allow for separate trampolines had a design flaw with the interaction between the function and function_graph tracers. The main flaw was the simplification of the use of multiple tracers having the same filter (like function and function_graph, that use the set_ftrace_filter file to filter their code). The design assumed that the two tracers could never run simultaneously as only one tracer can be used at a time. The problem with this assumption was that the function profiler could be implemented on top of the function graph tracer, and the function profiler could run at the same time as the function tracer. This caused the assumption to be broken and when ftrace detected this failed assumpiton it would spit out a nasty warning and shut itself down. Instead of using a single ftrace_ops that switches between the function and function_graph callbacks, the two tracers can again use their own ftrace_ops. But instead of having a complex hierarchy of ftrace_ops, the filter fields are placed in its own structure and the ftrace_ops can carefully use the same filter. This change took a bit to be able to allow for this and currently only the global_ops can share the same filter, but this new design can easily be modified to allow for any ftrace_ops to share its filter with another ftrace_ops. The first four patches deal with the change of allowing the ftrace_ops to share the filter (and this needs to go to 3.16 as well). The fifth patch fixes a bug that was also caused by the new changes but only for archs other than x86, and only if those archs implement a direct call to the function_graph tracer which they do not do yet but will in the future. It does not need to go to stable, but needs to be fixed before the other archs update their code to allow direct calls to the function_graph trampoline" * tag 'trace-fixes-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Use current addr when converting to nop in __ftrace_replace_code() ftrace: Fix function_profiler and function tracer together ftrace: Fix up trampoline accounting with looping on hash ops ftrace: Update all ftrace_ops for a ftrace_hash_ops update ftrace: Allow ftrace_ops to use the hashes from other ops

Upstream commit: 95d76acc7518d5 ("x86, irq: Count legacy IRQs by legacy_pic->nr_legacy_irqs instead of NR_IRQS_LEGACY") removed reserved interrupts for the platforms that do not have a legacy IOAPIC. Which breaks the boot on Intel MID platforms such as Medfield: BUG: unable to handle kernel NULL pointer dereference at 0000003a IP: [<c107079a>] setup_irq+0xf/0x4d [ 0.000000] *pdpt = 0000000000000000 *pde = 9bbf32453167e510 The culprit is an uncoditional setting of IRQ2 which is used as cascade IRQ on legacy platforms. It seems we have to check if we have enough legacy IRQs reserved before we can call setup_irq(). The fix adds such check in native_init_IRQ() and in setup_default_timer_irq().

Set the default EP max packet value as 8 bytes, because in the case of low-speed, 'ep_mps' is not set. Thus, the default value of 'ep_mps' should be considered for the case of low-speed.

2014-08-25at76c50x-usb: fix use after free on failure path in at76_probe()Alexey Khoroshilov1-2/+1
After commit 174beab7d445 ("at76c50x-usb: Don't perform DMA from stack memory") at76_delete_device() and usb_put_dev() are called both if at76_init_new_device() fails in at76_probe(). But at76_delete_device() does usb_put_dev(priv->dev) itself that means double usb_put_dev(). The patch avoids the problem by moving usb_put_dev() from at76_delete_device() to at76_disconnect().
