2019-08-23ARM: 8872/1: Use common outgoing-CPU-notification codePaul E. McKenney1-4/+2
This commit removes the open-coded CPU-offline notification with new common code. In particular, this change avoids calling scheduler code using RCU from an offline CPU that RCU is ignoring. This is a minimal change. A more intrusive change might invoke the cpu_check_up_prepare() and cpu_set_state_online() functions at CPU-online time, which would allow onlining throw an error if the CPU did not go offline properly.

A timing hazard exists when an early fork/exec thread begins exiting and sets its mm pointer to NULL while a separate core tries to update the section information. This commit ensures that the mm pointer is not NULL before setting its section parameters. The arguments provided by commit 11ce4b33aedc ("ARM: 8672/1: mm: remove tasklist locking from update_sections_early()") are equally valid for not requiring grabbing the task_lock around this check.

2019-08-23ARM: dts: sunxi: Add mdio bus sub-node to GMACChen-Yu Tsai34-132/+203
The DWMAC binding never supported having the Ethernet PHY node as a direct child to the controller, nor did it support the "phy" property as a way to specify which Ethernet PHY to use. What seemed to work was simply the implementation ignoring the "phy" property and instead probing all addresses on the MDIO bus and using the first available one. The recent switch from "phy" to "phy-handle" breaks the assumptions of the implementation, and does not match what the binding requires. The binding requires that if an MDIO bus is described, it shall be a sub-node with the "snps,dwmac-mdio" compatible string. Add a device node for the MDIO bus, and move the Ethernet PHY node under it. Also fix up the #address-cells and #size-cells properties where needed.

2019-08-23KVM: PPC: Book3S HV: Define usage types for rmap array in guest memslotSuraj Jitindar Singh2-5/+19
The rmap array in the guest memslot is an array of size number of guest pages, allocated at memslot creation time. Each rmap entry in this array is used to store information about the guest page to which it corresponds. For example for a hpt guest it is used to store a lock bit, rc bits, a present bit and the index of a hpt entry in the guest hpt which maps this page. For a radix guest which is running nested guests it is used to store a pointer to a linked list of nested rmap entries which store the nested guest physical address which maps this guest address and for which there is a pte in the shadow page table. As there are currently two uses for the rmap array, and the potential for this to expand to more in the future, define a type field (being the top 8 bits of the rmap entry) to be used to define the type of the rmap entry which is currently present and define two values for this field for the two current uses of the rmap array. Since the nested case uses the rmap entry to store a pointer, define this type as having the two high bits set as is expected for a pointer. Define the hpt entry type as having bit 56 set (bit 7 IBM bit ordering). Signed-off-by: Suraj Jitindar Singh <sjitindarsingh@gmail.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>

2019-08-22arm64: dts: fsl: Remove num-lanes property from PCIe nodesHou Zhiqiang5-17/+0
Remove the num-lanes property to avoid the driver setting the link width. On FSL Layerscape SoCs, the number of lanes assigned to PCIe controller is not fixed, it is determined by the selected SerDes protocol in the RCW (Reset Configuration Word). The PCIe link training is completed automatically through the selected SerDes protocol - the link width set-up is updated by hardware after power on reset, so the num-lanes property is not needed for Layerscape PCIe. The current num-lanes property was added erroneously, which actually indicates the maximum lanes the PCIe controller can support up to, instead of the lanes assigned to the PCIe controller. The link width set by SerDes protocol will be overridden by the num-lanes property, hence the subsequent re-training will fail when the assigned lanes do not match the value in the num-lanes property.

2019-08-22driver core: initialize a default DMA mask for platform deviceChristoph Hellwig7-22/+0
We still treat devices without a DMA mask as defaulting to 32-bits for both mask, but a few releases ago we've started warning about such cases, as they require special cases to work around this sloppyness. Add a dma_mask field to struct platform_device so that we can initialize the dma_mask pointer in struct device and initialize both masks to 32-bits by default, replacing similar functionality in m68k and powerpc. The arch_setup_pdev_archdata hooks is now unused and removed. Note that the code looks a little odd with the various conditionals because we have to support platform_device structures that are statically allocated.

Some Ux500 devices use the newer AB8505 PMIC instead of AB8500. Although they are very similar, there are subtle differences like the number of regulators or the available GPIO pins. At the moment, ste-dbx5x0.dtsi always configures the AB8500 PMIC. To support devices with AB8505, it is necessary to split the AB8500-specific parts into a separate .dtsi file.

While reviewing lockdown patches, I discovered that we still enable /dev/port (CONFIG_DEVPORT) in skiroot. /dev/port is used for old x86 style IO accesses. It's set up in drivers/char/mem.c, and is only created if arch_has_dev_port() returns true. Per arch/powerpc/include/asm/io.h, on PPC64 with PCI, this is only true if there's a legacy ISA bridge.

2019-08-22powerpc/eeh: Remove unused return path from eeh_pe_dev_traverse()Sam Bobroff4-47/+26
There are no users of the early-out return value from eeh_pe_dev_traverse(), so remove it.

2019-08-22powerpc/eeh: Fix crash when edev->pdev changesSam Bobroff1-15/+29
If a PCI device is removed during eeh_pe_report_edev(), between the calls to device_lock() and device_unlock(), edev->pdev will change and cause a crash as the wrong mutex is released. To correct this, hold the PCI rescan/remove lock while taking a copy of edev->pdev and performing a get_device() on it. Use this value to release the mutex, but also pass it through to the device driver's EEH handlers so that they always see the same device.

2019-08-22powerpc/eeh: Convert log messages to eeh_edev_* macrosSam Bobroff7-89/+39
Convert existing messages, where appropriate, to use the eeh_edev_* logging macros. The only effect should be minor adjustments to the log messages, apart from: - A new message in pseries_eeh_probe() "Probing device" to match the powernv case. - The "Probing device" message in pnv_eeh_probe() is now generated slightly later, which will mean that it is no longer emitted for devices that aren't probed due to the initial checks.

2019-08-22powerpc/eeh: Introduce EEH edev logging macrosSam Bobroff2-17/+11
Now that struct eeh_dev includes the BDFN of it's PCI device, make use of it to replace eeh_edev_info() with a set of dev_dbg()-style macros that only need a struct edev. With the BDFN available without the struct pci_dev, eeh_pci_name() is now unnecessary, so remove it. While only the "info" level function is used here, the others will be used in followup work.
