      arch/tile: enable interrupts in do_work_pending() · c19c6c95
      Chris Metcalf authored
      
      
      All the called functions expect interrupts to be enabled, and
      now one of them has started to warn about it, so make it correct.

      Pull Xen fixes from Konrad Rzeszutek Wilk:
       "This has four bug-fixes and one tiny feature that I forgot to put
        initially in my tree due to oversight.
      
        The feature is for kdump kernels to speed up the /proc/vmcore reading.
        There is a ram_is_pfn helper function that the different platforms can
        register for.  We are now doing that.
      
        The bug-fixes cover some embarrassing struct pv_cpu_ops variables
        being set to NULL on Xen (but not baremetal).  We had a similar issue
        in the past with {write|read}_msr_safe and this fills the three
        missing ones.  The other bug-fix is to make the console output (hvc)
        be capable of dealing with misbehaving backends and not fall flat on
        its face.  Lastly, a quirk for older XenBus implementations that came
        with an ancient v3.4 hypervisor (so RHEL5 based) - reading of certain
        non-existent attributes just hangs the guest during bootup - so we
        take precaution of not doing that on such older installations.
      
        Feature:
         - Register a pfn_is_ram helper to speed up reading of /proc/vmcore.
        Bug-fixes:
         - Three pvops call for Xen were undefined causing BUG_ONs.
         - Add a quirk so that the shutdown watches (used by kdump) are not
           used with older Xen (3.4).
         - Fix ungraceful state transition for the HVC console."

      xen/pv-on-hvm kexec: add quirk for Xen 3.4 and shutdown watches. · cb6b6df1
      Konrad Rzeszutek Wilk authored
      The commit 254d1a3f
      
      , titled
      "xen/pv-on-hvm kexec: shutdown watches from old kernel" assumes that the
      XenBus backend can deal with reading of values from:
       "control/platform-feature-xs_reset_watches":
      
          ... a patch for xenstored is required so that it
          accepts the XS_RESET_WATCHES request from a client (see changeset
          23839:42a45baf037d in xen-unstable.hg). Without the patch for xenstored
          the registration of watches will fail and some features of a PVonHVM
          guest are not available. The guest is still able to boot, but repeated
          kexec boots will fail."
      
      Sadly this is not true when using a Xen 3.4 hypervisor and booting a PVHVM
      guest. We end up hanging at:
      
        err = xenbus_scanf(XBT_NIL, "control",
                              "platform-feature-xs_reset_watches", "%d", &supported);
      
      This can easily be seen with guests hanging at xenbus_init:
      
      NX (Execute Disable) protection: active
      SMBIOS 2.4 present.
      DMI: Xen HVM domU, BIOS 3.4.0 05/13/2011
      Hypervisor detected: Xen HVM
      Xen version 3.4.
      Xen Platform PCI: I/O protocol version 1
      ... snip ..
      calling  xenbus_init+0x0/0x27e @ 1
      
      Reverting the commit or using the attached patch fixes the issue. This fix
      checks whether the hypervisor is older than 4.0 and if so does not try to
      perform the read.

      The hypervisor will trap it. However without this patch,
      we would crash as the .read_tscp is set to NULL. This patch
      fixes it and sets it to the native_read_tscp call.

      Pull second set of media updates from Mauro Carvalho Chehab:
       "Despite its size, most of the stuff here is trivial.  This series
        contains:
      
         - s5p-mfc: additions at the driver and at the core to support H.264
           hardware codec;
         - Some improvements at s5p and davinci embedded drivers;
         - Some V4L2 compliance fixes applied on a few drivers;
         - Several random trivial patches, including several fixes and a few

        Notes:
      
         1) Some Exynos media patches were dependent on some -arm fixes that
            got merged on changeset 782cd9ee.  That's why this pull request is
            based that changeset.
      
         2) As promised, I reviewed the pending VB2 DMABUF series.
      
            While setting a test environment, it was noticed that the upstream
            support for Samsung Exynos 4 boards (smdk310 and Origen) are
            broken upstream, likely due to regressions: both defconfigs are
            wrong and regulator settings for both boards are broken.  That,
            allied with some bug at the dummy regulator driver, causes OOPSes
            during boot time.
      
            Long story short: even fixing the above, the proposed patches
            OOPSed when running the DMABUF test.  Not sure yet if the OOPSes
            are due to some other undetected regressions, or due to some bug
            on the patches.
      
            Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

      Pull second set of pinctrl patches from Linus Walleij:
       "Here is a late pinctrl pull request with stuff that wasn't quite
        tested at the first pull request.
      
        The main reason to not hold off is that the modifications to
        irq_domain_add_simple() as reviewed by Rob Herring introduce new
        infrastructure for irqdomains that will be useful for the next cycle:
        instead of sprinkling irq descriptor allocation all over the kernel
        wherever a "legacy" domain is registered, which is necessary for any
        platform using sparse IRQs, and many irq chips are say GPIO
        controllers which may be used with several systems, some with sparse
        IRQs some not, we push this into the irq_domain_add_simple() so we can
        atleast do mistakes in one place.
      
        The irq_domain_add_simple() is currently unused in the kernel, so I
        need to provide a user.  The Nomadik stuff that goes with are changes
        to the driver I use day-to-day to make use of this facility (and a
        dependency), so see it as a way to eat my own dogfood: if this blows
        up the egg hits my face.
      
        A second round of pinctrl patches for v3.7:
         - Complement the Nomadik pinctrl driver with alternate Cx functions
           so it handles all oddities.
         - A patch to the IRQdomain to reform the simple irqdomain to handle
           IRQ descriptor allocation dynamically.
         - Use the above feature in the Nomadik pin controller."

      vfs: bogus warnings in fs/namei.c · 98f6ef64
      Arnd Bergmann authored
      
      
      The follow_link() function always initializes its *p argument,
      or returns an error, but when building with 'gcc -s', the compiler
      gets confused by the __always_inline attribute to the function
      and can no longer detect where the cookie was initialized.
      
      The solution is to always initialize the pointer from follow_link,
      even in the error path. When building with -O2, this has zero impact
      on generated code and adds a single instruction in the error path
      for a -Os build on ARM.
      
      Without this patch, building with gcc-4.6 through gcc-4.8 and
      CONFIG_CC_OPTIMIZE_FOR_SIZE results in:
      
      fs/namei.c: In function 'link_path_walk':

      --> nobody will take care of sending the new request.
      
      This is not very likely to happen though, because p9_write_work()
      being called with an empty unsent_req_list is not frequent.
      But this also means that taking the lock earlier will not be costly.

      Pull i2c-embedded changes from Wolfram Sang:
       "The changes for i2c-embedded include:
      
         - massive rework of the omap driver
         - massive rework of the at91 driver.  In fact, the old driver gets
           removed; I am okay with this approach since the old driver was
           depending on BROKEN and its limitations made it practically
           unusable, so people used bitbanging instead.  But even if there are
           users, there is no platform_data or module parameter which would
           need to be converted.  It is just another driver doing I2C
           transfers, just way better.  Modifications of arch/arm/at91 related
           files have proper acks from the maintainer.
         - new driver for R-Car I2C
         - devicetree and generic_clock conversions and fixes
         - usual driver fixes and changes.
      
        The rework patches have come a long way and lots of people have been
        involved in creating/testing them.  Most patches have been in
        linux-next at least since 3.6-rc5.  A few have been added in the last
        week, I have to admit.
      
        An unexpected (but welcome :)) peak in private life is the cause for
        that.  The "late" patches shouldn't cause any merge conflicts and I
        will have a special eye on them during the stabilization phase.  This
        is an exception and I want to have the patches in place properly in
        time again for the next kernels."

        Via Tony Lindgren:
         - A collection of OMAP regression fixes, in particular because
           firmware no longer sets up all pin states before starting the
           kernel.
         - cpufreq fixes for OMAP (Rafael is on vacation and this was
           pre-agreed).
         - A longer series of misc regression fixes and cleanups, warning
           removals, etc for OMAP
      
        From Arnd Bergmann:
         - A series of warning fixes for various platforms (defconfig builds)
      
        Misc:
         - A couple of tegra fixes, one for i.MX, some vt8500 fixes, etc."

      autofs4 - fix reset pending flag on mount fail · 49999ab2
      Ian Kent authored
      
      
      In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING
      mount pending flag is not cleared.
      
      One effect of this is when using the "browse" option, directory entry
      attributes show up with all "?"s due to the incorrect callback and
      subsequent failure return (when in fact no callback should be made).

      rcu: Advise most users not to enable RCU user mode · d677124b
      Frederic Weisbecker authored
      
      
      Discourage distros from enabling CONFIG_RCU_USER_QS
      because it brings overhead for no benefits yet.
      
      It's not a useful feature on its own until we can
      fully run an adaptive tickless kernel.

      Fix it by including linux/io.h which defines those functions.

      Merge branch 'for-3.7/core' of git://git.kernel.dk/linux-block · ce40be7a
      Linus Torvalds authored
      Pull block IO update from Jens Axboe:
       "Core block IO bits for 3.7.  Not a huge round this time, it contains:
      
         - First series from Kent cleaning up and generalizing bio allocation
           and freeing.
      
         - WRITE_SAME support from Martin.
      
         - Mikulas patches to prevent O_DIRECT crashes when someone changes
           the block size of a device.
      
         - Make bio_split() work on data-less bio's (like trim/discards).
      
         - A few other minor fixups."
      
      Fixed up silent semantic mis-merge as per Mikulas Patocka and Andrew
      Morton.  It is due to the VM no longer using a prio-tree (see commit
      6b2dbba8: "mm: replace vma prio_tree with an interval tree").
      
      So make set_blocksize() use mapping_mapped() instead of open-coding the
      internal VM knowledge that has changed.
