soc: ti: QMSS: Fix usage of irq_set_affinity_hint

2018-11-02T18:22:09Z

The Keystone QMSS driver is pretty damaged, in the sense that it does things like this: irq_set_affinity_hint(irq, to_cpumask(&cpu_map)); where cpu_map is a local variable. As we leave the function, this will point to nowhere-land, and things will end-up badly. Instead, let's use a proper cpumask that gets allocated, giving the driver a chance to actually work with things like irqbalance as well as have a hypothetical 64bit future.

Pull ARM SoC driver updates from Arnd Bergmann: "The most noteworthy SoC driver changes this time include: - The TEE subsystem gains an in-kernel interface to access the TEE from device drivers. - The reset controller subsystem gains a driver for the Qualcomm Snapdragon 845 Power Domain Controller. - The Xilinx Zynq platform now has a firmware interface for its platform management unit. This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller. Additional cleanups and bugfixes in SoC specific drivers include the Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (129 commits) firmware: tegra: bpmp: Implement suspend/resume support drivers: clk: Add ZynqMP clock driver dt-bindings: clock: Add bindings for ZynqMP clock driver firmware: xilinx: Add zynqmp IOCTL API for device control Documentation: xilinx: Add documentation for eemi APIs MAINTAINERS: imx: include drivers/firmware/imx path firmware: imx: add misc svc support firmware: imx: add SCU firmware driver support reset: Fix potential use-after-free in __of_reset_control_get() dt-bindings: arm: fsl: add scu binding doc soc: fsl: qbman: add interrupt coalesce changing APIs soc: fsl: bman_portals: defer probe after bman's probe soc: fsl: qbman: Use last response to determine valid bit soc: fsl: qbman: Add 64 bit DMA addressing requirement to QBMan soc: fsl: qbman: replace CPU 0 with any online CPU in hotplug handlers soc: fsl: qbman: Check if CPU is offline when initializing portals reset: qcom: PDC Global (Power Domain Controller) reset controller dt-bindings: reset: Add PDC Global binding for SDM845 SoCs reset: Grammar s/more then once/more than once/ bus: ti-sysc: Just use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS ...

Pull powerpc updates from Michael Ellerman: "Notable changes: - A large series to rewrite our SLB miss handling, replacing a lot of fairly complicated asm with much fewer lines of C. - Following on from that, we now maintain a cache of SLB entries for each process and preload them on context switch. Leading to a 27% speedup for our context switch benchmark on Power9. - Improvements to our handling of SLB multi-hit errors. We now print more debug information when they occur, and try to continue running by flushing the SLB and reloading, rather than treating them as fatal. - Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9). - Add support for physical memory up to 2PB in the linear mapping on 64-bit Book3S. We only support up to 512TB as regular system memory, otherwise the percpu allocator runs out of vmalloc space. - Add stack protector support for 32 and 64-bit, with a per-task canary. - Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP. - Support recognising "big cores" on Power9, where two SMT4 cores are presented to us as a single SMT8 core. - A large series to cleanup some of our ioremap handling and PTE flags. - Add a driver for the PAPR SCM (storage class memory) interface, allowing guests to operate on SCM devices (acked by Dan). - Changes to our ftrace code to handle very large kernels, where we need to use a trampoline to get to ftrace_caller(). And many other smaller enhancements and cleanups.

Pull Devicetree updates from Rob Herring: "A bit bigger than normal as I've been busy this cycle. There's a few things with dependencies and a few things subsystem maintainers didn't pick up, so I'm taking them thru my tree. The fixes from Johan didn't get into linux-next, but they've been waiting for some time now and they are what's left of what subsystem maintainers didn't pick up. Summary: - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4 - Work to get rid of direct accesses to struct device_node name and type pointers in preparation for removing them. New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code. This makes the support more uniform and enables building all dtbs on c6x, microblaze, and powerpc. - Various DT binding updates for Renesas r8a7744 SoC - Vendor prefixes for Facebook, OLPC - Restructuring of some ARM binding docs moving some peripheral bindings out of board/SoC binding files - New "secure-chosen" binding for secure world settings on ARM - Dual licensing of 2 DT IRQ binding headers" * tag 'devicetree-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (78 commits) ARM: dt: relicense two DT binding IRQ headers power: supply: twl4030-charger: fix OF sibling-node lookup NFC: nfcmrvl_uart: fix OF child-node lookup net: stmmac: dwmac-sun8i: fix OF child-node lookup net: bcmgenet: fix OF child-node lookup drm/msm: fix OF child-node lookup drm/mediatek: fix OF sibling-node lookup of: Add missing exports of node name compare functions dt-bindings: Add OLPC vendor prefix dt-bindings: misc: bk4: Add device tree binding for Liebherr's BK4 SPI bus dt-bindings: thermal: samsung: Add SPDX license identifier dt-bindings: clock: samsung: Add SPDX license identifiers dt-bindings: timer: ostm: Add R7S9210 support dt-bindings: phy: rcar-gen2: Add r8a7744 support dt-bindings: can: rcar_can: Add r8a7744 support dt-bindings: timer: renesas, cmt: Document r8a7744 CMT support dt-bindings: watchdog: renesas-wdt: Document r8a7744 support dt-bindings: thermal: rcar: Add device tree support for r8a7744 Documentation: dt: Add binding for /secure-chosen/stdout-path dt-bindings: arm: zte: Move sysctrl bindings to their own doc ...

net/kconfig: Make QCOM_QMI_HELPERS available when COMPILE_TEST

2018-10-24T07:11:35Z

The networking merge brought in the experimental support for the Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a dependency. But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM. As a result, a "make allmodconfig" complains WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS Depends on [n]: ARCH_QCOM && NET [=y] Selected by [m]: - ATH10K_SNOC [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && ATH10K [=m] && (ARCH_QCOM || COMPILE_TEST [=y]) Fix the config-time warning by making QCOM_QMI_HELPERS available when COMPILE_TEST, since the result seems to build fine.

soc/fsl/qbman: use ioremap_cache() instead of ioremap_prot(0)

2018-10-14T07:04:09Z

ioremap_prot() with flag set to 0 relies on a hack in __ioremap_caller() which adds PAGE_KERNEL flags when the handed flags don't look like a valid set of flags (ie don't include _PAGE_PRESENT) The intention being to map cached memory, use ioremap_cache() instead.
