Previously dbi accessors can be used to access data of size 4 bytes. But there might be situations (like accessing MSI_MESSAGE_CONTROL in order to set/get the number of required MSI interrupts in EP mode) where dbi accessors must be used to access data of size 2. This is in preparation for adding endpoint mode support to designware driver.

dwc has 2 dbi address space labeled dbics and dbics2. The existing helper to access dbi address space can access only dbics. However dbics2 has to be accessed for programming the BAR registers in the case of EP mode. This is in preparation for adding EP mode support to dwc driver.

Some platforms (like dra7xx) require only the least 28 bits of the corresponding 32 bit CPU address to be programmed in the address translation unit. This modified address is stored in io_base/mem_base/ cfg0_base/cfg1_base in dra7xx_pcie_host_init(). While this is okay for host mode where the address range is fixed, device mode requires different addresses to be programmed based on the host buffer address. Add a new ops to get the least 28 bits of the corresponding 32 bit CPU address and invoke it before programming the address translation unit.

The bug is that "val" is unsigned long but we only initialize 32 bits of it. Then we test "if (val)" and that might be true not because we set the bits but because some were never initialized.

Fix a crash from dereferencing a NULL dw_pcie_ops pointer. For example, on ARTPEC-6: Unable to handle kernel NULL pointer dereference at virtual address 00000004 pgd = c0204000 [00000004] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.11.0-rc3-next-20170321 #1 Hardware name: Axis ARTPEC-6 Platform task: db098000 task.stack: db096000 PC is at dw_pcie_writel_dbi+0x2c/0xd0 Prior to 442ec4c0 ("PCI: dwc: all: Split struct pcie_port into host-only and core structures"), every driver had a struct pcie_host_ops with function pointers, typically used as: if (pp->ops->readl_rc) return pp->ops->readl_rc(...); 442ec4c0 split struct pcie_host_ops into two pieces: struct dw_pcie_host_ops and struct dw_pcie_ops, so the above became: if (pci->ops->readl_dbi) return pci->ops->readl_dbi(...); But pcie-artpec6.c and pcie-designware-plat.c don't need the dw_pcie_ops pointers and didn't supply a pci->ops struct, which leads to NULL pointer dereferences. Supply an empty struct dw_pcie_ops to avoid the NULL pointer dereferences.

SZ_16M PEM resource size includes PEM-specific register and its children resources. Reservation of the whole SZ_16M range leads to child device driver failure when pcieport driver is requesting resources: pcieport 0004:1f:00.0: can't enable device: BAR 0 [mem 0x87e0c0f00000-0x87e0c0ffffff 64bit] not claimed So we cannot reserve full 16M here and instead we want to reserve PEM-specific register only which is SZ_64K. At the end increase PEM resource to SZ_16M since this is what thunder_pem_init() call expects for proper initialization.

During early days of PCI quirks support, ThunderX firmware did not provide PNP0c02 node with PCI configuration space and PEM-specific register ranges. This means that for legacy FW we are not reserving these resources and cannot gather PEM-specific resources for further PEM initialization. To support already deployed legacy FW, calculate PEM-specific ranges and provide resources reservation as fallback scenario into PEM driver when we could not gather PEM reg base from ACPI tables.

The host bridge memory window resource is inserted into the iomem_resource tree and cannot be deallocated until the host bridge itself is removed. Previously, the window was on the stack, which meant the iomem_resource entry pointed into the stack and was corrupted as soon as the probe function returned, which caused memory corruption and errors like this: pcie_iproc_bcma bcma0:8: resource collision: [mem 0x40000000-0x47ffffff] conflicts with PCIe MEM space [mem 0x40000000-0x47ffffff] Move the memory window resource from the stack into struct iproc_pcie so its lifetime matches that of the host bridge.

We call pcie_aspm_exit_link_state() when we remove a device. If the device is the last PCIe function to be removed below a bridge and the bridge has an ASPM link_state struct, we disable ASPM on the link. Disabling ASPM requires link->downstream (used in pcie_config_aspm_link()). We previously set link->downstream in pcie_aspm_cap_init(), but only if the device was not blacklisted. Removing the blacklisted device caused a NULL pointer dereference in the pcie_aspm_exit_link_state() -> pcie_config_aspm_link() path: # echo 1 > /sys/bus/pci/devices/0000\:0b\:00.0/remove ...

Make 'all' build all images appropriate for a platform - allow merging vectors code into .text section as a preparation step for XIP support - fix handling external FDT when the kernel is built without BLK_DEV_INITRD support * tag 'xtensa-20170303' of git://github.com/jcmvbkbc/linux-xtensa: xtensa: allow merging vectors into .text section xtensa: clean up bootable image build targets xtensa: move parse_tag_fdt out of #ifdef CONFIG_BLK_DEV_INITRD

Pull ARM SoC late DT updates from Arnd Bergmann: "These updates have been kept in a separate branch mostly because they rely on updates to the respective clk drivers to keep the shared header files in sync. This includes two branches for arm64 dt updates, both following up on earlier changes for the same platforms that are already merged: Samsung: - add USB3 support in Exynos7 - minor PM related updates Amlogic: - new machines: WeTek Set-top-boxes - various devices added to DT There are also a couple of bugfixes that trickled in since the start of the merge window: - The moxart_defconfig was not building the intended platform - CPU-hotplug was broken on ux500 - Coresight was broken on Juno (never worked)" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (26 commits) ARM: deconfig: fix the moxart defconfig ARM: ux500: resume the second core properly arm64: dts: juno: update definition for programmable replicator arm64: dts: exynos: Add regulators for Vbus and Vbus-Boost arm64: dts: exynos: Add USB 3.0 controller node for Exynos7 arm64: dts: exynos: Use macros for pinctrl configuration on Exynos7 pinctrl: dt-bindings: samsung: Add Exynos7 specific pinctrl macro definitions arm64: dts: exynos: Add initial configuration for DISP clocks for TM2/TM2e ARM64: dts: meson-gxbb-p200: add ADC laddered keys ARM64: dts: meson: meson-gx: add the SAR ADC ARM64: dts: meson-gxl: add the pwm_ao_b pin ARM64: dts: meson-gx: add the missing pwm_AO_ab node clk: gxbb: fix CLKID_ETH defined twice ARM64: dts: meson-gxl: rename Nexbox A95x for consistency clk: gxbb: add the SAR ADC clocks and expose them dt-bindings: amlogic: Add WeTek boards ARM64: dts: meson-gxbb: Add support for WeTek Hub and Play dt-bindings: vendor-prefix: Add wetek vendor prefix ARM64: dts: meson-gxm: Rename q200 and q201 DT files for consistency ARM64: dts: meson-gx: Add HDMI HPD/DDC pinctrl nodes ...

Pull vfs 'statx()' update from Al Viro. This adds the new extended stat() interface that internally subsumes our previous stat interfaces, and allows user mode to specify in more detail what kind of information it wants. It also allows for some explicit synchronization information to be passed to the filesystem, which can be relevant for network filesystems: is the cached value ok, or do you need open/close consistency, or what? From David Howells. Andreas Dilger points out that the first version of the extended statx interface was posted June 29, 2010: https://www.spinics.net/lists/linux-fsdevel/msg33831.html * 'rebased-statx' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: statx: Add a system call to make enhanced file info available
