2017-09-10m68k: Add braces to __pmd(x) initializer to kill compiler warningGeert Uytterhoeven
With gcc 4.1.2: include/linux/swapops.h: In function ‘swp_entry_to_pmd’: include/linux/swapops.h:294: warning: missing braces around initializer include/linux/swapops.h:294: warning: (near initialization for ‘(anonymous).pmd’) Due to a GCC zero initializer bug (#53119), the standard "(pmd_t){ 0 }" initializer is not accepted by all GCC versions. In addition, on m68k pmd_t is an array instead of a single value, so we need "(pmd_t){ { 0 }, }" instead of "(pmd_t){ 0 }".

2017-09-09sparc64: Handle additional cases of no fault loadsRob Gardner
Load instructions using ASI_PNF or other no-fault ASIs should not cause a SIGSEGV or SIGBUS. A garden variety unmapped address follows the TSB miss path, and when no valid mapping is found in the process page tables, the miss handler checks to see if the access was via a no-fault ASI. It then fixes up the target register with a zero, and skips the no-fault load instruction. But different paths are taken for data access exceptions and alignment traps, and these do not respect the no-fault ASI. We add checks in these paths for the no-fault ASI, and fix up the target register and TPC just like in the TSB miss case.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "Slightly more changes than usual this time: - KDump Kernel IOMMU take-over code for AMD IOMMU. The code now tries to preserve the mappings of the kernel so that master aborts for devices are avoided. Master aborts cause some devices to fail in the kdump kernel, so this code makes the dump more likely to succeed when AMD IOMMU is enabled. - common flush queue implementation for IOVA code users. The code is still optional, but AMD and Intel IOMMU drivers had their own implementation which is now unified. - finish support for iommu-groups. All drivers implement this feature now so that IOMMU core code can rely on it. - finish support for 'struct iommu_device' in iommu drivers. All drivers now use the interface. - new functions in the IOMMU-API for explicit IO/TLB flushing. This will help to reduce the number of IO/TLB flushes when IOMMU drivers support this interface. - support for mt2712 in the Mediatek IOMMU driver - new IOMMU driver for QCOM hardware - system PM support for ARM-SMMU - shutdown method for ARM-SMMU-v3 - some constification patches - various other small improvements and fixes" * tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (87 commits) iommu/vt-d: Don't be too aggressive when clearing one context entry iommu: Introduce Interface for IOMMU TLB Flushing iommu/s390: Constify iommu_ops iommu/vt-d: Avoid calling virt_to_phys() on null pointer iommu/vt-d: IOMMU Page Request needs to check if address is canonical. arm/tegra: Call bus_set_iommu() after iommu_device_register() iommu/exynos: Constify iommu_ops iommu/ipmmu-vmsa: Make ipmmu_gather_ops const iommu/ipmmu-vmsa: Rereserving a free context before setting up a pagetable iommu/amd: Rename a few flush functions iommu/amd: Check if domain is NULL in get_domain() and return -EBUSY iommu/mediatek: Fix a build warning of BIT(32) in ARM iommu/mediatek: Fix a build fail of m4u_type iommu: qcom: annotate PM functions as __maybe_unused iommu/pamu: Fix PAMU boot crash memory: mtk-smi: Degrade SMI init to module_init iommu/mediatek: Enlarge the validate PA range for 4GB mode iommu/mediatek: Disable iommu clock when system suspend iommu/mediatek: Move pgtable allocation into domain_alloc iommu/mediatek: Merge 2 M4U HWs into one iommu domain ...

2017-09-08arch: define CPU_BIG_ENDIAN for all fixed big endian archsBabu Moger
Patch series "Define CPU_BIG_ENDIAN or warn for inconsistencies", v3. While working on enabling queued rwlock on SPARC, found this following code in include/asm-generic/qrwlock.h which uses CONFIG_CPU_BIG_ENDIAN to clear a byte. static inline u8 *__qrwlock_write_byte(struct qrwlock *lock) { return (u8 *)lock + 3 * IS_BUILTIN(CONFIG_CPU_BIG_ENDIAN); } Problem is many of the fixed big endian architectures don't define CPU_BIG_ENDIAN and clears the wrong byte. Define CPU_BIG_ENDIAN for all the fixed big endian architecture to fix it. Also found few more references of this config parameter in drivers/of/base.c drivers/of/fdt.c drivers/tty/serial/earlycon.c drivers/tty/serial/serial_core.c Be aware that this may cause regressions if someone has worked-around problems in the above code already. Remove the work-around.

2017-09-08treewide: make "nr_cpu_ids" unsignedAlexey Dobriyan
First, number of CPUs can't be negative number. Second, different signnnedness leads to suboptimal code in the following cases: 1) kmalloc(nr_cpu_ids * sizeof(X)); "int" has to be sign extended to size_t. 2) while (loff_t *pos < nr_cpu_ids) MOVSXD is 1 byte longed than the same MOV. Other cases exist as well. Basically compiler is told that nr_cpu_ids can't be negative which can't be deduced if it is "int".

2017-09-08alpha: add support for memset16Matthew Wilcox
Alpha already had an optimised fill-memory-with-16-bit-quantity assembler routine called memsetw(). It has a slightly different calling convention from memset16() in that it takes a byte count, not a count of words. That's the same convention used by ARM's __memset routines, so rename Alpha's routine to match and add a memset16() wrapper around it. Then convert Alpha's scr_memsetw() to call memset16() instead of memsetw().

2017-09-08mm/memory_hotplug: introduce add_pagesMichal Hocko
There are new users of memory hotplug emerging. Some of them require different subset of arch_add_memory. There are some which only require allocation of struct pages without mapping those pages to the kernel address space. We currently have __add_pages for that purpose. But this is rather lowlevel and not very suitable for the code outside of the memory hotplug. E.g. x86_64 wants to update max_pfn which should be done by the caller. Introduce add_pages() which should care about those details if they are needed. Each architecture should define its implementation and select CONFIG_ARCH_HAS_ADD_PAGES. All others use the currently existing __add_pages.

Add thp migration's core code, including conversions between a PMD entry and a swap entry, setting PMD migration entry, removing PMD migration entry, and waiting on PMD migration entries. This patch makes it possible to support thp migration. If you fail to allocate a destination page as a thp, you just split the source thp as we do now, and then enter the normal page migration. If you succeed to allocate destination thp, you enter thp migration. Subsequent patches actually enable thp migration for each caller of page migration by allowing its get_new_page() callback to allocate thps.

2017-09-08mm: x86: move _PAGE_SWP_SOFT_DIRTY from bit 7 to bit 1Naoya Horiguchi
_PAGE_PSE is used to distinguish between a truly non-present (_PAGE_PRESENT=0) PMD, and a PMD which is undergoing a THP split and should be treated as present. But _PAGE_SWP_SOFT_DIRTY currently uses the _PAGE_PSE bit, which would cause confusion between one of those PMDs undergoing a THP split, and a soft-dirty PMD. Dropping _PAGE_PSE check in pmd_present() does not work well, because it can hurt optimization of tlb handling in thp split. Thus, we need to move the bit. In the current kernel, bits 1-4 are not used in non-present format since commit 00839ee3b299 ("x86/mm: Move swap offset/type up in PTE to work around erratum"). So let's move _PAGE_SWP_SOFT_DIRTY to bit 1. Bit 7 is used as reserved (always clear), so please don't use it for other purpose.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Nothing really major this release, despite quite a lot of activity. Just lots of things all over the place. Some things of note include: - Access via perf to a new type of PMU (IMC) on Power9, which can count both core events as well as nest unit events (Memory controller etc). - Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page Walk Cache (PWC) flushes when the structure of the tree is not changing. - Reworks/cleanups of do_page_fault() to modernise it and bring it closer to other architectures where possible. - Rework of our page table walking so that THP updates only need to send IPIs to CPUs where the affected mm has run, rather than all CPUs. - The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems. This avoids problems with the percpu allocator on systems with very sparse NUMA layouts. - STRICT_KERNEL_RWX support on PPC32. - A new sched domain topology for Power9, to capture the fact that pairs of cores may share an L2 cache. - Power9 support for VAS, which is a new mechanism for accessing coprocessors, and initial support for using it with the NX compression accelerator. - Major work on the instruction emulation support, adding support for many new instructions, and reworking it so it can be used to implement the emulation needed to fixup alignment faults. - Support for guests under PowerVM to use the Power9 XIVE interrupt controller. And probably that many things again that are almost as interesting, but I had to keep the list short. Plus the usual fixes and cleanups as always.
