Recent toolchains force the TOC to be 256 byte aligned. We need to enforce this alignment in the zImage linker script, otherwise pointers to our TOC variables (__toc_start) could be incorrect. If the actual start of the TOC and __toc_start don't have the same value we crash early in the zImage wrapper. Cc: stable@vger.kernel.org Suggested-by:

Pull tracing fixes from Steven Rostedt: "There was some breakage with the changes for jump labels in the 4.11 merge window: - powerpc broke as jump labels uses the two LSB bits as flags in initialization. A check was added to make sure that all jump label entries were 4 bytes aligned, but powerpc didn't work that way for modules. Adding an alignment in the module linker script appeared to be the best solution. - Jump labels also added an anonymous union to access those LSB bits as a normal long. But because this structure had static initialization, it broke older compilers that could not statically initialize anonymous unions without brackets. - The command line parameter for setting function graph filter broke the "EMPTY_HASH" descriptor by modifying it instead of creating a new hash to hold the entries. - The command line parameter ftrace_graph_max_depth was added to allow its setting at boot time. It uses existing code and only the command line hook was added. This is not really a fix, but as it uses existing code without affecting anything else, I added it to this release. It was ready before the merge window closed, but I wanted to let it sit in linux-next for a couple of days first" * tag 'trace-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace/graph: Add ftrace_graph_max_depth kernel parameter tracing: Add #undef to fix compile error jump_label: Add comment about initialization order for anonymous unions jump_label: Fix anonymous union initialization module: set __jump_table alignment to 8 ftrace/graph: Do not modify the EMPTY_HASH for the function_graph filter tracing: Fix code comment for ftrace_ops_get_func()

Always increment/decrement ucount->count under the ucounts_lock. The increments are there already and moving the decrements there means the locking logic of the code is simpler. This simplification in the locking logic fixes a race between put_ucounts and get_ucounts that could result in a use-after-free because the count could go zero then be found by get_ucounts and then be freed by put_ucounts. A bug presumably this one was found by a combination of syzkaller and KASAN. JongWhan Kim reported the syzkaller failure and Dmitry Vyukov spotted the race in the code.

We have a big list of selects under CONFIG_PPC, and currently they're completely unsorted. This means people tend to add new selects at the bottom of the list, and so two commits which both add a new select will often conflict. Instead sort it alphabetically. This is nicer in and of itself, but also means two commits that add a new select will have a greater chance of not conflicting. Add a note at the top and bottom asking people to keep it sorted. And while we're here pad out the 'if' expressions to make them stand out. Suggested-by:

On POWER9 the ibm,client-architecture-support (CAS) negotiation process has been updated to change how the host to guest negotiation is done for the new hash/radix mmu as well as the nest mmu, process tables and guest translation shootdown (GTSE). This is documented in the unreleased PAPR ACR "CAS option vector additions for P9". The host tells the guest which options it supports in ibm,arch-vec-5-platform-support. The guest then chooses a subset of these to request in the CAS call and these are agreed to in the ibm,architecture-vec-5 property of the chosen node. Thus we read ibm,arch-vec-5-platform-support and make our selection before calling CAS. We then parse the ibm,architecture-vec-5 property of the chosen node to check whether we should run as hash or radix. ibm,arch-vec-5-platform-support format: index value pairs: <index, val> ... <index, val> index: Option vector 5 byte number val: Some representation of supported values Signed-off-by:

On POWER9 the hypervisor requires the guest to decide whether it would like to use a hash or radix mmu model at the time it calls ibm,client-architecture-support (CAS) based on what the hypervisor has said it's allowed to do. It is possible to disable radix by passing "disable_radix" on the command line. The next patch will add support for the new CAS format, thus we need to parse the command line before calling CAS so we can correctly select which mmu we would like to use. Signed-off-by:

The CPPR (Current Processor Priority Register) of a XICS interrupt presentation controller contains a value N, such that only interrupts with a priority "more favoured" than N will be received by the CPU, where "more favoured" means "less than". So if the CPPR has the value 5 then only interrupts with a priority of 0-4 inclusive will be received. In theory the CPPR can support a value of 0 to 255 inclusive. In practice Linux only uses values of 0, 4, 5 and 0xff. Setting the CPPR to 0 rejects all interrupts, setting it to 0xff allows all interrupts. The values 4 and 5 are used to differentiate IPIs from external interrupts. Setting the CPPR to 5 allows IPIs to be received but not external interrupts. The CPPR emulation in the OPAL XICS implementation only directly supports priorities 0 and 0xff. All other priorities are considered equivalent, and mapped to a single priority value internally. This means when using icp-opal we can not allow IPIs but not externals. This breaks Linux's use of priority values when a CPU is hot unplugged. After migrating IRQs away from the CPU that is being offlined, we set the priority to 5, meaning we still want the offline CPU to receive IPIs. But the effect of the OPAL XICS emulation's use of a single priority value is that all interrupts are rejected by the CPU. With the CPU offline, and not receiving IPIs, we may not be able to wake it up to bring it back online. The first part of the fix is in icp_opal_set_cpu_priority(). CPPR values of 0 to 4 inclusive will correctly cause all interrupts to be rejected, so we pass those CPPR values through to OPAL. However if we are called with a CPPR of 5 or greater, the caller is expecting to be able to allow IPIs but not external interrupts. We know this doesn't work, so instead of rejecting all interrupts we choose the opposite which is to allow all interrupts. This is still not correct behaviour, but we know for the only existing caller (xics_migrate_irqs_away()), that it is the better option. The other part of the fix is in xics_migrate_irqs_away(). Instead of setting priority (CPPR) to 0, and then back to 5 before migrating IRQs, we migrate the IRQs before setting the priority back to 5. This should have no effect on an ICP backend with a working set_priority(), and on icp-opal it means we will keep all interrupts blocked until after we've finished doing the IRQ migration. Additionally we wait for 5ms after doing the migration to make sure there are no IRQs in flight.

The recent commit to allow calling OPAL calls in real mode, commit ab9bad0e ("powerpc/powernv: Remove separate entry for OPAL real mode calls"), introduced a bug when CONFIG_JUMP_LABEL=n. The commit moved the "mfmsr r12" prior to the call to OPAL_BRANCH, but we missed that OPAL_BRANCH clobbers r12 when jump labels are disabled. This leads to us using the tracepoint refcount as the MSR value, typically zero, and saving that into PACASAVEDMSR. When we return from OPAL we use that value as the MSR value for rfid, meaning we switch to 32-bit BE real mode - hilarity ensues. Fix it by using r11 in OPAL_BRANCH, which is not live at the time the macro is used in OPAL_CALL. Fixes: ab9bad0e ("powerpc/powernv: Remove separate entry for OPAL real mode calls") Suggested-by:

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

Pull block layer fixes from Jens Axboe: "A collection of fixes for this merge window, either fixes for existing issues, or parts that were waiting for acks to come in. This pull request contains: - Allocation of nvme queues on the right node from Shaohua. This was ready long before the merge window, but waiting on an ack from Bjorn on the PCI bit. Now that we have that, the three patches can go in. - Two fixes for blk-mq-sched with nvmeof, which uses hctx specific request allocations. This caused an oops. One part from Sagi, one part from Omar. - A loop partition scan deadlock fix from Omar, fixing a regression in this merge window. - A three-patch series from Keith, closing up a hole on clearing out requests on shutdown/resume. - A stable fix for nbd from Josef, fixing a leak of sockets. - Two fixes for a regression in this window from Jan, fixing a problem with one of his earlier patches dealing with queue vs bdi life times. - A fix for a regression with virtio-blk, causing an IO stall if scheduling is used. From me. - A fix for an io context lock ordering problem. From me" * 'for-linus' of git://git.kernel.dk/linux-block: block: Move bdi_unregister() to del_gendisk() blk-mq: ensure that bd->last is always set correctly block: don't call ioc_exit_icq() with the queue lock held for blk-mq block: Initialize bd_bdi on inode initialization loop: fix LO_FLAGS_PARTSCAN hang nvme: Complete all stuck requests blk-mq: Provide freeze queue timeout blk-mq: Export blk_mq_freeze_queue_wait nbd: stop leaking sockets blk-mq: move update of tags->rqs to __blk_mq_alloc_request() blk-mq: kill blk_mq_set_alloc_data() blk-mq: make blk_mq_alloc_request_hctx() allocate a scheduler request blk-mq-sched: Allocate sched reserved tags as specified in the original queue tagset nvme: allocate nvme_queue in correct node PCI: add an API to get node from vector blk-mq: allocate blk_mq_tags and requests in correct node
