2016-05-15powerpc/fsl-pci: Add a workaround for PCI 5 erratachenhui zhao1-0/+24
Issue: As a master, the PCI IP block can combine a memory write to the last PCI double word (4 bytes) of a cacheline with a 4 byte memory write to the first PCI double word of the subsequent cacheline. This affects 32-bit PCI target devices that blindly assert STOP on memory-write transactions, without detecting that the data beat being transferred is the last data beat of the transaction. It can cause a hang. PCI-X operation is not affected by this erratum. Workaround: Setting the bit MDS in the PCI Bus Function Register will disable the combining of crossing cacheline boundary requests into one burst transaction. Therefore, it can prevent the errata scenario from occurring. This errata exists in MPC8543, MPC8543E, MPC8545, MPC8545E, MPC8547, MPC8547E, MPC8548 and MPC8548E. Refer to PCI 5 in MPC8548 errata document.

Add new Port Write handler registration interfaces that attach PW handlers to local mport device objects. This is different from old interface that attaches PW callback to individual RapidIO device. The new interfaces are intended for use for common event handling (e.g. hot-plug notifications) while the old interface is available for individual device drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for kernel v4.6. There is quite a lot of interesting stuff going on. The patches to other subsystems and arch-wide are ACKed as far as possible, though I consider things like per-arch <asm/gpio.h> as essentially a part of the GPIO subsystem so it should not be needed. Core changes: - The gpio_chip is now a *real device*. Until now the gpio chips were just piggybacking the parent device or (gasp) floating in space outside of the device model. We now finally make GPIO chips devices. The gpio_chip will create a gpio_device which contains a struct device, and this gpio_device struct is kept private. Anything that needs to be kept private from the rest of the kernel will gradually be moved over to the gpio_device. - As a result of making the gpio_device a real device, we have added resource management, so devm_gpiochip_add_data() will cut down on overhead and reduce code lines. A huge slew of patches convert almost all drivers in the subsystem to use this. - Building on making the GPIO a real device, we add the first step of a new userspace ABI: the GPIO character device. We take small steps here, so we first add a pure *information* ABI and the tool "lsgpio" that will list all GPIO devices on the system and all lines on these devices. We can now discover GPIOs properly from userspace. We still have not come up with a way to actually *use* GPIOs from userspace. - To encourage people to use the character device for the future, we have it always-enabled when using GPIO. The old sysfs ABI is still opt-in (and can be used in parallel), but is marked as deprecated. We will keep it around for the foreseeable future, but it will not be extended to cover ever more use cases. Cleanup: - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h> includes. This dates back to when GPIO was an opt-in feature and no shared library even existed: just a header file with proper prototypes was provided and all semantics were up to the arch to implement. These patches make the GPIO chip even more a proper device and cleans out leftovers of the old in-kernel API here and there. Still some cruft is left but it's very little now. - There is still some clamping of return values for .get() going on, but we now return sane values in the vast majority of drivers and the errorpath is sanitized. Some patches for powerpc, blackfin and unicore still drop in. - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO implementations to use gpiochip_add_data() and cut down on code lines. - MPC8xxx is converted to use the generic GPIO helpers. - ATH79 is converted to use the generic GPIO helpers. New drivers: - WinSystems WS16C48 - Acces 104-DIO-48E - F81866 (a F7188x variant) - Qoric (a MPC8xxx variant) - TS-4800 - SPI serializers (pisosr): simple 74xx shift registers connected to SPI to obtain a dirt-cheap output-only GPIO expander. - Texas Instruments TPIC2810 - Texas Instruments TPS65218 - Texas Instruments TPS65912 - X-Gene (ARM64) standby GPIO controller" * tag 'gpio-v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (194 commits) Revert "Share upstreaming patches" gpio: mcp23s08: Fix clearing of interrupt. gpiolib: Fix comment referring to gpio_*() in gpiod_*() gpio: pca953x: Fix pca953x_gpio_set_multiple() on 64-bit gpio: xgene: Fix kconfig for standby GIPO contoller gpio: Add generic serializer DT binding gpio: uapi: use 0xB4 as ioctl() major gpio: tps65912: fix bad merge Revert "gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free" gpio: omap: drop dev field from gpio_bank structure gpio: mpc8xxx: Slightly update the code for better readability gpio: mpc8xxx: Remove *read_reg and *write_reg from struct mpc8xxx_gpio_chip gpio: mpc8xxx: Fixup setting gpio direction output gpio: mcp23s08: Add support for mcp23s18 dt-bindings: gpio: altera: Fix altr,interrupt-type property gpio: add driver for MEN 16Z127 GPIO controller gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free gpio: timberdale: Switch to devm_ioremap_resource() gpio: ts4800: Add IMX51 dependency gpiolib: rewrite gpiodev_add_to_list ...

Function to cause an IPI by directly updating the MFFR register in the XICS. The function is meant for real-mode callers since they cannot use the smp_ops->cause_ipi function which uses an ioremapped address. Normal usage is for the the KVM real mode code to set the IPI message using smp_muxed_ipi_message_pass and then invoke icp_native_cause_ipi_rm to cause the actual IPI. The function requires kvm_hstate.xics_phys to have been initialized with the physical address of XICS.

2016-01-15mm, dax, pmem: introduce pfn_tDan Williams1-5/+4
For the purpose of communicating the optional presence of a 'struct page' for the pfn returned from ->direct_access(), introduce a type that encapsulates a page-frame-number plus flags. These flags contain the historical "page_link" encoding for a scatterlist entry, but can also denote "device memory". Where "device memory" is a set of pfns that are not part of the kernel's linear mapping by default, but are accessed via the same memory controller as ram. The motivation for this new type is large capacity persistent memory that needs struct page entries in the 'memmap' to support 3rd party DMA (i.e. O_DIRECT I/O with a persistent memory source/target). However, we also need it in support of maintaining a list of mapped inodes which need to be unmapped at driver teardown or freeze_bdev() time.

2015-12-11EDAC, mpc85xx: Make mpc85xx-pci-edac a platform deviceScott Wood2-10/+27
Originally the mpc85xx-pci-edac driver bound directly to the PCI controller node. Commit 905e75c46dba ("powerpc/fsl-pci: Unify pci/pcie initialization code") turned the PCI controller code into a platform device. Since we can't have two drivers binding to the same device, the EDAC code was changed to be called into as a library-style submodule. However, this doesn't work if the EDAC driver is built as a module. Commit 8d8fcba6d1ea ("EDAC: Rip out the edac_subsys reference counting") exposed another problem with this approach -- mpc85xx_pci_err_probe() was being called in the same early boot phase that the PCI controller is initialized, rather than in the device_initcall phase that the EDAC layer expects. This caused a crash on boot. To fix this, the PCI controller code now creates a child platform device specifically for EDAC, which the mpc85xx-pci-edac driver binds to.

Pull block IO poll support from Jens Axboe: "Various groups have been doing experimentation around IO polling for (really) fast devices. The code has been reviewed and has been sitting on the side for a few releases, but this is now good enough for coordinated benchmarking and further experimentation. Currently O_DIRECT sync read/write are supported. A framework is in the works that allows scalable stats tracking so we can auto-tune this. And we'll add libaio support as well soon.

2015-11-05uaccess: reimplement probe_kernel_address() using probe_kernel_read()Andrew Morton1-1/+1
probe_kernel_address() is basically the same as the (later added) probe_kernel_read(). The return value on EFAULT is a bit different: probe_kernel_address() returns number-of-bytes-not-copied whereas probe_kernel_read() returns -EFAULT. All callers have been checked, none cared. probe_kernel_read() can be overridden by the architecture whereas probe_kernel_address() cannot. parisc, blackfin and um do this, to insert additional checking. Hence this patch possibly fixes obscure bugs, although there are only two probe_kernel_address() callsites outside arch/. My first attempt involved removing probe_kernel_address() entirely and converting all callsites to use probe_kernel_read() directly, but that got tiresome. This patch shrinks mm/slab_common.o by 218 bytes. For a single probe_kernel_address() callsite.

2015-10-28powerpc/msi: Fix section mismatch warning in msi_bitmap_alloc()Denis Kirjanov1-1/+1
Building with CONFIG_DEBUG_SECTION_MISMATCH gives the following warning: The function .msi_bitmap_alloc() references the function __init .memblock_virt_alloc_try_nid(). Memory allocation in msi_bitmap_alloc() uses either slab allocator or memblock boot time allocator depending on slab_is_available(). So the section mismatch warning is correct, but in practice there is no bug so mark msi_bitmap_alloc() as __init_refok.

mpic_irq_set_wake return -ENXIO for non FSL MPIC and sets IRQF_NO_SUSPEND flag for FSL ones. enable_irq_wake already returns -ENXIO if irq_set_wak is not implemented. Also there's no need to set the IRQF_NO_SUSPEND flag as it doesn't guarantee wakeup for that interrupt. This patch removes the redundant mpic_irq_set_wake and sets the IRQCHIP_SKIP_SET_WAKE for only FSL MPIC.

2015-10-17powerpc/fsl_pci: Don't set up inbound windows in kdump crash kernelScott Wood1-23/+61
Otherwise, because the top end of the crash kernel is treated as the absolute top of memory rather than the beginning of a reserved region, in-flight DMA from the previous kernel that targets areas above the crash kernel can trigger a storm of PCI errors. We only do this for kdump, not normal kexec, in case kexec is being used to upgrade to a kernel that wants a different inbound memory map.
