      drm/i915: Fix modeset state confusion in the load detect code · 9128b040
      Daniel Vetter authored
      This is a tricky story of the new atomic state handling and the legacy
      code fighting over each another. The bug at hand is an underrun of the
      framebuffer reference with subsequent hilarity caused by the load
      detect code. Which is peculiar since the the exact same code works
      fine as the implementation of the legacy setcrtc ioctl.
      
      Let's look at the ingredients:
      
      - Currently our code is a crazy mix of legacy modeset interfaces to
        set the parameters and half-baked atomic state tracking underneath.
        While this transition is going we're using the transitional plane
        helpers to update the atomic side (drm_plane_helper_disable/update
        and friends), i.e. plane->state->fb. Since the state structure owns
        the fb those functions take care of that themselves.
      
        The legacy state (specifically crtc->primary->fb) is still managed
        by the old code (and mostly by the drm core), with the fb reference
        counting done by callers (core drm for the ioctl or the i915 load
        detect code). The relevant commit is

            drm/i915: Move to atomic plane helpers (v9)
      
      - drm_plane_helper_disable has special code to handle multiple calls
        in a row - it checks plane->crtc == NULL and bails out. This is to
        match the proper atomic implementation which needs the crtc to get
        at the implied locking context atomic updates always need. See

            drm/plane-helper: transitional atomic plane helpers
      
      - The universal plane code split out the implicit primary plane from
        the CRTC into it's own full-blown drm_plane object. As part of that
        the setcrtc ioctl (which updated both the crtc mode and primary
        plane) learned to set crtc->primary->crtc on modeset to make sure
        the plane->crtc assignments statate up to date in
      
        commit e13161af
        Author: Matt Roper <matthew.d.roper@intel.com>
        Date:   Tue Apr 1 15:22:38 2014 -0700
      
            drm: Add drm_crtc_init_with_planes() (v2)
      
        Unfortunately we've forgotten to update the load detect code. Which
        wasn't a problem since the load detect modeset is temporary and
        always undone before we drop the locks.
      
      - Finally there is a organically grown history (i.e. don't ask) around
        who sets the legacy plane->fb for the various driver entry points.
        Originally updating that was the drivers duty, but for almost all
        places we've moved that (plus updating the refcounts) into the core.
        Again the exception is the load detect code.
      
      Taking all together the following happens:
      - The load detect code doesn't set crtc->primary->crtc. This is only
        really an issue on crtcs never before used or when userspace
        explicitly disabled the primary plane.
      
      - The plane helper glue code short-circuits because of that and leaves
        a non-NULL fb behind in plane->state->fb and plane->fb. The state
        fb isn't a real problem (it's properly refcounted on its own), it's
        just the canary.
      
      - Load detect code drops the reference for that fb, but doesn't set
        plane->fb = NULL. This is ok since it's still living in that old
        world where drivers had to clear the pointer but the core/callers
        handled the refcounting.
      
      - On the next modeset the drm core notices plane->fb and takes care of
        refcounting it properly by doing another unref. This drops the
        refcount to zero, leaving state->plane now pointing at freed memory.
      
      - intel_plane_duplicate_state still assume it owns a reference to that
        very state->fb and bad things start to happen.
      
      Fix this all by applying the same duct-tape as for the legacy setcrtc
      ioctl code and set crtc->primary->crtc properly.

      mm: add missing __PAGETABLE_{PUD,PMD}_FOLDED defines · c07af4f1
      Kirill A. Shutemov authored
      Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page
      table levels folded.  Usually, these defines are provided by
      <asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>.
      
      But some architectures fold page table levels in a custom way.  They
      need to define these macros themself.  This patch adds missing defines.
      
      The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc()
      and __pud_alloc() on architectures without these page table levels.

      mm: page_alloc: revert inadvertent !__GFP_FS retry behavior change · cc873177
      Johannes Weiner authored
      Historically, !__GFP_FS allocations were not allowed to invoke the OOM
      killer once reclaim had failed, but nevertheless kept looping in the
      allocator.
      
      Commit 9879de73 ("mm: page_alloc: embed OOM killing naturally into
      allocation slowpath"), which should have been a simple cleanup patch,
      accidentally changed the behavior to aborting the allocation at that
      point.  This creates problems with filesystem callers (?) that currently
      rely on the allocator waiting for other tasks to intervene.
      
      Revert the behavior as it shouldn't have been changed as part of a
      cleanup patch.

      This changes a user interface, so do it before the release and before

      max_used_pages is defined as atomic_long_t so we need to use unsigned
      long to keep temporary value for it rather than int which is smaller
      than unsigned long in a 64 bit system.

      drivers/rtc/rtc-ds1685.c: fix conditional in ds1685_rtc_sysfs_time_regs_{show,store} · b00eeaed
      Joshua Kinard authored
      Fix a conditional statement checking for NULL in both
      ds1685_rtc_sysfs_time_regs_show and ds1685_rtc_sysfs_time_regs_store
      that was using a logical AND when it should be using a logical OR so
      that we fail out of the function properly if the condition ever
      evaluates to true.

      nilfs2: fix potential memory overrun on inode · 957ed60b
      Ryusuke Konishi authored
      Each inode of nilfs2 stores a root node of a b-tree, and it turned out to
      have a memory overrun issue:
      
      Each b-tree node of nilfs2 stores a set of key-value pairs and the number
      of them (in "bn_nchildren" member of nilfs_btree_node struct), as well as
      a few other "bn_*" members.
      
      Since the value of "bn_nchildren" is used for operations on the key-values
      within the b-tree node, it can cause memory access overrun if a large
      number is incorrectly set to "bn_nchildren".
      
      For instance, nilfs_btree_node_lookup() function determines the range of
      binary search with it, and too large "bn_nchildren" leads
      nilfs_btree_node_get_key() in that function to overrun.
      
      As for intermediate b-tree nodes, this is prevented by a sanity check
      performed when each node is read from a drive, however, no sanity check
      has been done for root nodes stored in inodes.
      
      This patch fixes the issue by adding missing sanity check against b-tree
      root nodes so that it's called when on-memory inodes are read from ifile,
      inode metadata file.

      scripts/gdb: add empty package initialization script · 586a1a12
      Jan Kiszka authored
      This got lost during the initial merge process: Python requires an
      __init__.py script, even if empty, in order to accept a directory as
      package.  Add it, this time as a non-empty file.

      u8 cannot contain a value larger than 0xff, hence drop the checks.
      Wrapping the checks in unlikely() indicated some sense of humor, though ;-)

      rtc: ds1685: fix ds1685_rtc_alarm_irq_enable build error · 682354d4
      Arnd Bergmann authored
      The newly added ds1685 driver causes a build error when enabled without
      CONFIG_RTC_INTF_DEV:
      
        drivers/rtc/rtc-ds1685.c:919:22: error: 'ds1685_rtc_alarm_irq_enable' undeclared here (not in a function)
          .alarm_irq_enable = ds1685_rtc_alarm_irq_enable,
      
      Apparently the driver was incorrectly changed to reflect the interface
      change from 16380c15 ("RTC: Convert rtc drivers to use the
      alarm_irq_enable method"), which removed the respective #ifdef from all
      other rtc drivers.
      
      This does the same change that was merged for the other drivers before and
      removes the #ifdef, allowing the interrupts to be enabled through the
      in-kernel rtc interface independent of the existence of /dev/rtc.
