      Linus Torvalds 提交于
      Pull x86 mm tree changes from Ingo Molnar:
       "The biggest change is full PAT support from Jürgen Gross:
      
           The x86 architecture offers via the PAT (Page Attribute Table) a
           way to specify different caching modes in page table entries.  The
           PAT MSR contains 8 entries each specifying one of 6 possible cache
           modes.  A pte references one of those entries via 3 bits:
           _PAGE_PAT, _PAGE_PWT and _PAGE_PCD.
      
           The Linux kernel currently supports only 4 different cache modes.
           The PAT MSR is set up in a way that the setting of _PAGE_PAT in a
           pte doesn't matter: the top 4 entries in the PAT MSR are the same
           as the 4 lower entries.
      
           This results in the kernel not supporting e.g. write-through mode.
           Especially this cache mode would speed up drivers of video cards
           which now have to use uncached accesses.
      
           OTOH some old processors (Pentium) don't support PAT correctly and
           the Xen hypervisor has been using a different PAT MSR configuration
           for some time now and can't change that as this setting is part of
           the ABI.
      
           This patch set abstracts the cache mode from the pte and introduces
           tables to translate between cache mode and pte bits (the default
           cache mode "write back" is hard-wired to PAT entry 0).  The tables
           are statically initialized with values being compatible to old
           processors and current usage.  As soon as the PAT MSR is changed
           (or - in case of Xen - is read at boot time) the tables are changed
           accordingly.  Requests of mappings with special cache modes are
           always possible now, in case they are not supported there will be a
           fallback to a compatible but slower mode.
      
           Summing it up, this patch set adds the following features:
      
            - capability to support WT and WP cache modes on processors with
              full PAT support
      
            - processors with no or uncorrect PAT support are still working as
              today, even if WT or WP cache mode are selected by drivers for
              some pages
      
            - reduction of Xen special handling regarding cache mode
      
        Another change is a boot speedup on ridiculously large RAM systems,
        plus other smaller fixes"

      Linus Torvalds 提交于
      Pull irq domain updates from Thomas Gleixner:
       "The real interesting irq updates:
      
         - Support for hierarchical irq domains:
      
           For complex interrupt routing scenarios where more than one
           interrupt related chip is involved we had no proper representation
           in the generic interrupt infrastructure so far.  That made people
           implement rather ugly constructs in their nested irq chip
           implementations.  The main offenders are x86 and arm/gic.
      
           To distangle that mess we have now hierarchical irqdomains which
           seperate the various interrupt chips and connect them via the
           hierarchical domains.  That keeps the domain specific details
           internal to the particular hierarchy level and removes the
           criss/cross referencing of chip internals.  The resulting hierarchy
           for a complex x86 system will look like this:
      
              vector          mapped: 74
                msi-0         mapped: 2
                dmar-ir-1     mapped: 69
                  ioapic-1    mapped: 4
                  ioapic-0    mapped: 20
                  pci-msi-2   mapped: 45
                dmar-ir-0     mapped: 3
                  ioapic-2    mapped: 1
                  pci-msi-1   mapped: 2
                htirq         mapped: 0
      
           Neither ioapic nor pci-msi know about the dmar interrupt remapping
           between themself and the vector domain.  If interrupt remapping is
           disabled ioapic and pci-msi become direct childs of the vector
           domain.
      
           In hindsight we should have done that years ago, but in hindsight
           we always know better :)
      
         - Support for generic MSI interrupt domain handling
      
           We have more and more non PCI related MSI interrupts, so providing
           a generic infrastructure for this is better than having all
           affected architectures implementing their own private hacks.
      
         - Support for PCI-MSI interrupt domain handling, based on the generic
           MSI support.
      
           This part carries the pci/msi branch from Bjorn Helgaas pci tree to
           avoid a massive conflict.  The PCI/MSI parts are acked by Bjorn.
      
        I have two more branches on top of this.  The full conversion of x86
        to hierarchical domains and a partial conversion of arm/gic"

      x86/microcode/intel: Fish out the stashed microcode for the BSP · 25cdb9c8
      Borislav Petkov 提交于
      I'm such a moron! The simple solution of saving the BSP patch
      for use on resume was too simple (and wrong!), hint:
      sizeof(struct microcode_intel).
      
      What needs to be done instead is to fish out the microcode patch
      we have stashed previously and apply that on the BSP in case the
      late loader hasn't been utilized.
      
      So do that instead.

      Pull scheduler updates from Ingo Molnar:
       "The main changes in this cycle are:
      
         - 'Nested Sleep Debugging', activated when CONFIG_DEBUG_ATOMIC_SLEEP=y.
      
           This instruments might_sleep() checks to catch places that nest
           blocking primitives - such as mutex usage in a wait loop.  Such
           bugs can result in hard to debug races/hangs.
      
           Another category of invalid nesting that this facility will detect
           is the calling of blocking functions from within schedule() ->
           sched_submit_work() -> blk_schedule_flush_plug().
      
           There's some potential for false positives (if secondary blocking
           primitives themselves are not ready yet for this facility), but the
           kernel will warn once about such bugs per bootup, so the warning
           isn't much of a nuisance.
      
           This feature comes with a number of fixes, for problems uncovered
           with it, so no messages are expected normally.
      
         - Another round of sched/numa optimizations and refinements, for
           CONFIG_NUMA_BALANCING=y.

       "On the kernel side there's few changes, the one that stands out is
        PEBS machine state sampling support on x86, by Stephane Eranian.
      
        On the tooling side:
      
        User visible tooling changes:
      
         - Don't open the DWARF info multiple times, keeping instead a dwfl
           handle in struct dso, greatly speeding up 'perf report' on powerpc.
           (Sukadev Bhattiprolu)
      
         - Introduce PARSE_OPT_DISABLED option flag and use it to avoid
           showing undersired options in tools that provides frontends to
           'perf record', like sched, kvm, etc (Namhyung Kim)
      
         - Fallback to kallsyms when using the minimal 'ELF' loader (Arnaldo
           Carvalho de Melo)
      
         - Fix annotation with kcore (Adrian Hunter)
      
         - Support source line numbers in annotate using a hotkey (Andi Kleen)
      
         - Callchain improvements including:
           * Enable printing the srcline in the history
           * Make get_srcline fall back to sym+offset (Andi Kleen)
      
         - TUI hist_entry browser fixes, including showing missing overhead
           value for first level callchain.  Detected comparing the output of
           --stdio/--gui (that matched) with --tui, that had this problem.
           (Namhyung Kim)
      
         - Support handling complete branch stacks as histograms (Andi Kleen)
      
        Tooling infrastructure changes:
      
         - Prep work for supporting per-pkg and snapshot counters in 'perf
           stat' (Jiri Olsa)
      
         - 'perf stat' refactorings, moving stuff from it to evsel.c to use in
           per-pkg/snapshot format changes (Jiri Olsa)
      
         - Add per-pkg format file parsing (Matt Fleming)
      
         - Clean up libelf feature support code (Namhyung Kim)
      
         - Add gzip decompression support for kernel modules (Namhyung Kim)
      
         - More prep patches for Intel PT, including a a thread stack and more
           stuff made available via the database export mechanism (Adrian
           Hunter)
      
         - More Intel PT work, including a facility to export sample data
           (comms, threads, symbol names, etc) in a database friendly way,
           with an script to use this to create a postgresql database.
           (Adrian Hunter)
      
         - Make sure that thread->mg->machine points to the machine where the
           thread exists (it was being set only for the kmaps kernel modules
           case, do it as well for the mmaps) and use it to shorten function

        There are two sets of patches that change significant portions of

         - Will Deacon has done a set of patches to ensure that all

           get them by including asm-generic/io.h.
      
           These functions are commonly used on ARM specific drivers to avoid
           expensive L2 cache synchronization implied by the normal
           {read,write}{b,w,l,q}, but we need to define them on all
           architectures in order to share the drivers across architectures
           and to enable CONFIG_COMPILE_TEST configurations for them
      
         - Thierry Reding has done an unrelated set of patches that extends

      Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann:
       "The GPMC driver has traditionally been considered a part of the OMAP
        platform code and tightly interweaved with some of the boards.
      
        With this cleanup, it has finally come to the point where it makes
        sense to move it out of arch/arm into drivers/memory, where we already
        have other drivers for similar hardware.  The cleanups are still
        ongoing, with the goal of eventually having a standalone driver that
        does not require an interface to architecture code.
      
        This is a separate branch because of dependencies on multiple other
        branches, and to keep the drivers changes separate from the normal
        cleanups"

      Pull ARM SoC DT updates from Arnd Bergmann:
       "The DT branch adds a lot of new stuff for additional SoC and board
        support.  The branch is the largest one and contains 513 out of the
        total 972 non-merge arm-soc changesets for 3.19.
      
        Most of the changes are about enabling additional on-chip devices for
        existing machines, but there are also an unusual number of new SoC
        types being added this time:
      
         - AMLogic Meson8
         - ARM Realview in DT mode

         - STMicroelectronics STiH410
         - Samsung Exynos4415
      
        The level of support for the above differs widely, some are just stubs
        with nothing more than CPU, memory and a UART, but others are fairly
        complete.  As usual, these get extended over time.
      
        There are also many new boards getting added, this is the list of
        model strings that are showing up in new dts files:

      Pull ARM SoC cleanups from Arnd Bergmann:
       "The remaining cleanups for 3.19 are to a large part result of
        devicetree conversion nearing completion on two other platforms
        besides AT91:
      
         - Like AT91, Renesas shmobile is in the process to migrate to DT and
           multiplatform, but using a different approach of doing it one SoC
           at a time.  For 3.19, the r8a7791 platform and associated "Koelsch"
           board are considered complete and we remove the non-DT
           non-multiplatform support for this.
      
         - The ARM Versatile Express has supported DT and multiplatform for a
           long time, but we have still kept the legacy board files around,
           because not all drivers were fully working before.  We have finally
           taken the last step to remove the board files.
      
        Other changes in this branch are preparation for the later branches or
        just unrelated to the more interesting changes:
      
         - The dts files for arm64 get moved into per-vendor directories for a
           clearer structure.

       "On Atmel AT91, the conversion to device tree is now considered
        complete, and all machines that were not already converted in 3.18 are
        assumed to be unused and dropped by the maintainer.
      
        All remaining board files that were written in C are dropped, and the
        ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
        altogether.  Cleaning up the last pieces was great fun, so I took the
        time to do some of the coding myself and removed several hundred code
        lines that ended up unused after the board files were done.
      
        There are still a couple of AT91 specific device drivers that are not
        converted to DT (CF, USB-OTG) and currently not working, and the
        platform itself is not "multiplatform"-enabled, but both issues are
        going to be taken care of in the 3.20 cycle.

      Linus Torvalds 提交于
      Pull device mapper updates from Mike Snitzer:
      
       - Significant DM thin-provisioning performance improvements to meet
         performance requirements that were requested by the Gluster
         distributed filesystem.
      
         Specifically, dm-thinp now takes care to aggregate IO that will be
         issued to the same thinp block before issuing IO to the underlying
         devices.  This really helps improve performance on HW RAID6 devices
         that have a writeback cache because it avoids RMW in the HW RAID
         controller.
      
       - Some stable fixes: fix leak in DM bufio if integrity profiles were
         enabled, use memzero_explicit in DM crypt to avoid any potential for
         information leak, and a DM cache fix to properly mark a cache block
         dirty if it was promoted to the cache via the overwrite optimization.
      
       - A few simple DM persistent data library fixes
      
       - DM cache multiqueue policy block promotion improvements.
      
       - DM cache discard improvements that take advantage of range
         (multiblock) discard support in the DM bio-prison.  This allows for
         much more efficient bulk discard processing (e.g.  when mkfs.xfs
         discards the entire device).
      
       - Some small optimizations in DM core and RCU deference cleanups
      
       - DM core changes to suspend/resume code to introduce the new internal
         suspend/resume interface that the DM thin-pool target now uses to
         suspend/resume active thin devices when the thin-pool must
         suspend/resume.
      
         This avoids forcing userspace to track all active thin volumes in a
         thin-pool when the thin-pool is suspended for the purposes of
         metadata or data space resize.

      Pull regulator updates from Mark Brown:
       "The main thing this time around is support for suspend mode
        configuration from DT which will enable some very useful power savings
        on systems where we can't rely on the bootloader configuration.  We
        still don't really support dynamic configuration of this at runtime,
        that may come later if there is any demand.
      
        Summary:
         - Support for specifying the target regulation mode and voltage
           during system suspend via DT, enabling power savings in that mode.
         - Reduce the default verbosity of the logging on boot, improving boot
           times especially for systems with very large numbers of regulators.
         - Lots of cleanups and fixes for Maxim PMIC drivers.
