      watchdog: sp5100_tco: Fix wrong indirect I/O access for getting value of reserved bits · 10ab329b
      Takahisa Tanaka authored
      In case of SB800 or later chipset and re-programming MMIO address(*),
      sp5100_tco module may read incorrect value of reserved bit, because the module
      reads a value from an incorrect I/O address. However, this bug doesn't cause
      a problem, because when re-programming MMIO address, by chance the module
      writes zero (this is BIOS's default value) to the low three bits of register.
      * In most cases, PC with SB8x0 or later chipset doesn't need to re-programming
        MMIO address, because such PC can enable AcpiMmio and can use 0xfed80b00 for
        watchdog register base address.
      
      This patch fixes this bug.

      watchdog: at91sam9: at91_wdt_dt_ids cannot be __init · 6c41e474
      Arnd Bergmann authored
      The device IDs are referenced by the driver and potentially
      used beyond the init time, as kbuild correctly warns
      about. Remove the __initconst annotation.
      
      Without this patch, building at91_dt_defconfig results in:

      Pull EDAC fixes and ghes-edac from Mauro Carvalho Chehab:
       "For:
      
         - Some fixes at edac drivers (i7core_edac, sb_edac, i3200_edac);
         - error injection support for i5100, when EDAC debug is enabled;
         - fix edac when it is loaded builtin (early init for the subsystem);
         - a "Firmware First" EDAC driver, allowing ghes to report errors via
           EDAC (ghes-edac).
      
        With regards to ghes-edac, this fixes a longstanding BZ at Red Hat
        that happens with Nehalem and Sandy Bridge CPUs: when both GHES and
        i7core_edac or sb_edac are running, the error reports are
        unpredictable, as both BIOS and OS race to access the registers.  With
        ghes-edac, the EDAC core will refuse to register any other concurrent
        memory error driver.
      
        This patchset moves the ghes struct definitions to a separate header
        file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to
        register/unregister and to report errors via ghes-edac.  Those changes
        were acked by ghes driver maintainer (Huang)."

      Fix mis-merge of intel_powerclamp.c resulting in compile error · 19cc90f5
      Linus Torvalds authored
      The new intel_powerclamp thermal cooling device driver was merged in
      commit 2af78448 (Pull thermal management updates from Zhang Rui)
      without any data conflicts.  But there was a more subtle conflict I
      missed: the driver uses MAX_USER_RT_PRIO, but commit 8bd75c77
      ("sched/rt: Move rt specific bits into new header file") had moved that
      define from <linux/sched.h> to <linux/sched/rt.h>.
      
      Which caused this build failure:
      
        drivers/thermal/intel_powerclamp.c: In function ‘clamp_thread’:
        drivers/thermal/intel_powerclamp.c:360:21: error: ‘MAX_USER_RT_PRIO’ undeclared (first use in this function)
        drivers/thermal/intel_powerclamp.c:360:21: note: each undeclared identifier is reported only once for each function it appears in
      
      And because I don't do a full "make allmodconfig" build after each pull,
      I didn't notice until too late.  So now the fix is here, separately from
      the merge commit.

      Pull ARM SoC mvebu platform changes from Olof Johansson:
       "This series contains changes for the Marvell EBU platforms (mvebu,
        orion, kirkwood, dove) that were not part of the first set of pull
        requests because of dependencies on the MMC tree, and being submitted
        a little late.
      
        Notable changes are:
      
         - More devices get moved out of board files into device tree
           descriptions.  The remaining devices listed in there have patches
           that will get sent for 3.10, after which we can remove a lot of the
           board files entirely.  We are doing the pinctrl and mmc drivers
           here, ethernet and PCI still remain.
      
         - SMP support for mvebu is improved with support for the local
           interrupt controller.
      
         - The Guruplug board file gets replaced with a DT description.
      
        Unfortunately, the dependency on the MMC tree turned out to be a much
        larger problem than expected, when the MMC maintainer rebased the
        patches in his tree that all of the patches in this branch are based
        on, which caused merge conflicts between the new and old versions of
        those patches.
      
        To work around the merge conflicts, this branch rebases all patches on
        top of the respective MMC patches that did get merged into 3.9.  The
        patches are all identical to the versions that were part of
        linux-next, but have a new commit date."

        platform.
      
        The base patch of the branch changes the format of the dts files to a
        slightly different format that makes it easier to do derivative board
        definitions, but it also introduces a lot of churn in the process
        since every line of the file is touched.
      
        On top of that are a handful of the regular changes; enabling more
        boards as DT-based instead of legacy board files (mx25pdk), enabling
        another driver for devicetree and thus adding bindings (onewire), etc.

      Pull nfsd changes from J Bruce Fields:
       "Miscellaneous bugfixes, plus:
      
         - An overhaul of the DRC cache by Jeff Layton.  The main effect is
           just to make it larger.  This decreases the chances of intermittent
           errors especially in the UDP case.  But we'll need to watch for any
           reports of performance regressions.
      
         - Containerized nfsd: with some limitations, we now support
           per-container nfs-service, thanks to extensive work from Stanislav
           Kinsbursky over the last year."
      
      Some notes about conflicts, since there were *two* non-data semantic
      conflicts here:
      
       - idr_remove_all() had been added by a memory leak fix, but has since
         become deprecated since idr_destroy() does it for us now.
      
       - xs_local_connect() had been added by this branch to make AF_LOCAL
         connections be synchronous, but in the meantime Trond had changed the
         calling convention in order to avoid a RCU dereference.
      
      There were a couple of more obvious actual source-level conflicts due to
      the hlist traversal changes and one just due to code changes next to
      each other, but those were trivial.

      Pull Ceph updates from Sage Weil:
       "A few groups of patches here.  Alex has been hard at work improving
        the RBD code, layout groundwork for understanding the new formats and
        doing layering.  Most of the infrastructure is now in place for the
        final bits that will come with the next window.
      
        There are a few changes to the data layout.  Jim Schutt's patch fixes
        some non-ideal CRUSH behavior, and a set of patches from me updates
        the client to speak a newer version of the protocol and implement an
        improved hashing strategy across storage nodes (when the server side
        supports it too).
      
        A pair of patches from Sam Lang fix the atomicity of open+create
        operations.  Several patches from Yan, Zheng fix various mds/client
        issues that turned up during multi-mds torture tests.
      
        A final set of patches expose file layouts via virtual xattrs, and
        allow the policies to be set on directories via xattrs as well
        (avoiding the awkward ioctl interface and providing a consistent
        interface for both kernel mount and ceph-fuse users)."
