2018-08-01Revert "staging: gasket: page table: hold references to device and pci_dev"Todd Poynor
gasket_free_dev() is called only from driver PCI probe and remove function. It is guaranteed that that pci_dev structure is not going anywhere during that time; there is no need to take this additional reference. This reverts commit dd9d1502feea3c23d412f289aad79e1d4e86d45d.

This was bisected back to commit bfd40eaff5ab ("mm: fix vma_is_anonymous() false-positives"). create_mspace_with_base() in the trace above, utilizes ashmem, and with ashmem, for shared mappings we use shmem_zero_setup(), which sets the vma->vm_ops to &shmem_vm_ops. But for private ashmem mappings nothing sets the vma->vm_ops. Looking at the problematic patch, it seems to add a requirement that one call vma_set_anonymous() on a vma, otherwise the dummy_vm_ops will be used. Using the dummy_vm_ops seem to triggger SIGBUS when traversing unmapped pages. Thus, this patch adds a call to vma_set_anonymous() for ashmem private mappings and seems to avoid the reported problem.

The function long_sleep() calls mdelay() when in an interrupt handler. But only charlcd_clear_display() and charlcd_init_display calls long_sleep(), and my tool finds that the two functions are never called in an interrupt handler. Thus mdelay() and in_interrupt() are not necessary. This is found by a static analysis tool named DCNS written by myself.

2018-08-01net: change Exar/Neterion menu items to be alphabeticalJon Mason
Neterion was standalone for several years, then acquired by Exar and shutdown in 11 months without ever making any new Exar branded adapters. Users would probably think of them as Neterion and not Exar (as there have been no follow-on adapters and the vast majority ever sold were under the Neterion name). 6c541b4595a2 ("net: ethernet: Sort Kconfig sourcing alphabetically") sorted Kconfig sourcing based on directory names, but in a couple cases, the menu item text is quite different from the directory name and is not sorted correctly: drivers/net/ethernet/neterion/Kconfig => "Exar devices" To address that and clear up any confusion about the name, "Exar" was changed to "Neterion (Exar)" and the relevant entries in the Makefile and Kconfig were reordered to match the alphabetical organization.

2018-08-01be2net: gather debug info and reset adapter (only for Lancer) on a tx-timeoutSuresh Reddy
This patch handles a TX-timeout as follows: 1) This patch gathers and prints the following info that can help in diagnosing the cause of a TX-timeout. a) TX queue and completion queue entries. b) SKB and TCP/UDP header details. 2) For Lancer NICs (TX-timeout recovery is not supported for BE3/Skyhawk-R NICs), it recovers from the TX timeout as follows: a) On a TX-timeout, driver sets the PHYSDEV_CONTROL_FW_RESET_MASK bit in the PHYSDEV_CONTROL register. Lancer firmware goes into an error state and indicates this back to the driver via a bit in a doorbell register. b) Driver detects this and calls be_err_recover(). DMA is disabled, all pending TX skbs are unmapped and freed (be_close()). All rings are destroyed (be_clear()). c) The driver waits for the FW to re-initialize and re-creates all rings along with other data structs (be_resume()) Signed-off-by: Suresh Reddy <suresh.reddy@broadcom.com> Signed-off-by: David S.

2018-08-01mmc: sunxi: remove output of virtual base addressAndre Przywara
Recent Linux versions refuse to print actual virtual kernel addresses, to not give a hint about the location of the kernel in a randomized virtual address space. This affects the output of the sunxi MMC controller driver, which now produces the rather uninformative line: [ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8 Since the virtual base address is not really interesting in the first place, let's just drop this value. The same applies to Linux' notion of the interrupt number, which is independent from the GIC SPI number. We have the physical address as part of the DT node name, which is way more useful for debugging purposes. To keep a success message in the driver, we make this purpose explicit with the word "initialized", plus print some information that is not too obvious and that we learned while probing the device: the maximum request size and whether it uses the new timing mode. So the output turns into: [ 1.750626] sunxi-mmc 1c0f000.mmc: initialized, max. request size: 16384 KB, uses new timings mode [ 1.786699] sunxi-mmc 1c11000.mmc: initialized, max. request size: 2048 KB Signed-off-by: Andre Przywara <andre.przywara@arm.com> Acked-by: Maxime Ripard <maxime.ripard@bootlin.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2018-08-01gpiolib-acpi: make sure we trigger edge events at least once on bootBenjamin Tissoires
On some systems using edge triggered ACPI Event Interrupts, the initial state at boot is not setup by the firmware, instead relying on the edge irq event handler running at least once to setup the initial state. 2 known examples of this are: 1) The Surface 3 has its _LID state controlled by an ACPI operation region triggered by a GPIO event: OperationRegion (GPOR, GeneralPurposeIo, Zero, One) Field (GPOR, ByteAcc, NoLock, Preserve) { Connection ( GpioIo (Shared, PullNone, 0x0000, 0x0000, IoRestrictionNone, "\\_SB.GPO0", 0x00, ResourceConsumer, , ) { // Pin list 0x004C } ), HELD, 1 } Method (_E4C, 0, Serialized) // _Exx: Edge-Triggered GPE { If ((HELD == One)) { ^^LID.LIDB = One } Else { ^^LID.LIDB = Zero Notify (LID, 0x80) // Status Change } Notify (^^PCI0.SPI1.NTRG, One) // Device Check } Currently, the state of LIDB is wrong until the user actually closes or open the cover. We need to trigger the GPIO event once to update the internal ACPI state. Coincidentally, this also enables the Surface 2 integrated HID sensor hub which also requires an ACPI gpio operation region to start initialization. 2) Various Bay Trail based tablets come with an external USB mux and TI T1210B USB phy to enable USB gadget mode. The mux is controlled by a GPIO which is controlled by an edge triggered ACPI Event Interrupt which monitors the micro-USB ID pin. When the tablet is connected to a PC (or no cable is plugged in), the ID pin is high and the tablet should be in gadget mode. But the GPIO controlling the mux is initialized by the firmware so that the USB data lines are muxed to the host controller. This means that if the user wants to use gadget mode, the user needs to first plug in a host-cable to force the ID pin low and then unplug it and connect the tablet to a PC, to get the ACPI event handler to run and switch the mux to device mode, This commit fixes both by running the event-handler once on boot. Note that the running of the event-handler is done from a late_initcall, this is done because the handler AML code may rely on OperationRegions registered by other builtin drivers. This avoids errors like these: [ 0.133026] ACPI Error: No handler for Region [XSCG] ((____ptrval____)) [GenericSerialBus] (20180531/evregion-132) [ 0.133036] ACPI Error: Region GenericSerialBus (ID=9) has no handler (20180531/exfldio-265) [ 0.133046] ACPI Error: Method parse/execution failed \_SB.GPO2._E12, AE_NOT_EXIST (20180531/psparse-516) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> [hdegoede: Document BYT USB mux reliance on initial trigger] [hdegoede: Run event handler from a late_initcall, rather then immediately] Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
