      ARM: OMAP2+: Fix build error after merge · 2b43e4e5
      Tony Lindgren authored
      Commit 9890ce44 (ARM: get rid of asm/irq.h in asm/prom.h)
      removed include of asm/irq.h in asm/prom.h. This commit
      together with recent omap cleanup to remove io.h causes
      build breakage:
      
      arrch/arm/mach-omap2/control.c: In function 'omap3_ctrl_write_boot_mode':
      arch/arm/mach-omap2/control.c:238: error:
      'OMAP343X_CTRL_BASE' undeclared (first use in this function)
      ...
      
      Fix this by including hardware.h directly where needed
      instead of relying on asm/irq.h in asm/prom.h.

      One patch fixes an bug in the ARM/MSM IOMMU code which returned sucess
      in the unmap function even when an error occured and the other patch
      adds a workaround into the AMD IOMMU driver to better handle broken IVRS
      ACPI tables (this patch fixes the case when a device is not listed in
      the table but actually translated by the iommu).

      pcmcia: fix socket refcount decrementing on each resume · 025e4ab3
      Russell King authored
      This fixes a memory-corrupting bug: not only does it cause the warning,
      but as a result of dropping the refcount to zero, it causes the
      pcmcia_socket0 device structure to be freed while it still has
      references, causing slab caches corruption.  A fatal oops quickly
      follows this warning - often even just a 'dmesg' following the warning
      causes the kernel to oops.
      
      While testing suspend/resume on an ARM device with PCMCIA support, and a
      CF card inserted, I found that after five suspend and resumes, the
      kernel would complain, and shortly die after with slab corruption.
      
        WARNING: at include/linux/kref.h:41 kobject_get+0x28/0x50()
      
      As the message doesn't give a clue about which kobject, and the built-in
      debugging in drivers/base/power/main.c happens too late, this was added
      right before each get_device():
      
        printk("%s: %p [%s] %u\n", __func__, dev, kobject_name(&dev->kobj), atomic_read(&dev->kobj.kref.refcount));

      Looking at commit 7b24e798 ("pcmcia: split up central event handler"),
      the following change was made to cs.c:
      
                      return 0;
              }
       #endif
      -
      -       send_event(skt, CS_EVENT_PM_RESUME, CS_EVENT_PRI_LOW);
      +       if (!(skt->state & SOCKET_CARDBUS) && (skt->callback))
      +               skt->callback->early_resume(skt);
              return 0;
       }
      
      And the corresponding change in ds.c is from:
      
      -static int ds_event(struct pcmcia_socket *skt, event_t event, int priority)
      -{
      -       struct pcmcia_socket *s = pcmcia_get_socket(skt);

      -                       ds_event(skt, CS_EVENT_CARD_REMOVAL, CS_EVENT_PRI_HIGH);

      -                       destroy_cis_cache(skt);

      -    }
      
      -    pcmcia_put_socket(s);
      
      -    return 0;
      -} /* ds_event */
      
      to:
      
      +static int pcmcia_bus_early_resume(struct pcmcia_socket *skt)
      +{
      +       if (!verify_cis_cache(skt)) {
      +               pcmcia_put_socket(skt);
      +               return 0;
      +       }
      
      +       dev_dbg(&skt->dev, "cis mismatch - different card\n");

      +}
      
      As can be seen, the original function called pcmcia_get_socket() and
      pcmcia_put_socket() around the guts, whereas the replacement code
      calls pcmcia_put_socket() only in one path.  This creates an imbalance
      in the refcounting.
      
      Testing with pcmcia_put_socket() put removed shows that the bug is gone:

      drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmax · ec44fd42
      Axel Lin authored
      In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and
      pltfm->als_vmax is 0.  This does not make sense.  I think what we want
      here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV.
      
      Both als_vmin and als_vmax local variables will be set to
      pltfm->als_vmin and pltfm->als_vmax by a few lines latter.  Thus also
      remove a redundant assignment for als_vmin and als_vmax in this patch.

      mm: compaction: check for overlapping nodes during isolation for migration · dc908600
      Mel Gorman authored
      When isolating pages for migration, migration starts at the start of a
      zone while the free scanner starts at the end of the zone.  Migration
      avoids entering a new zone by never going beyond the free scanned.
      
      Unfortunately, in very rare cases nodes can overlap.  When this happens,
      migration isolates pages without the LRU lock held, corrupting lists
      which will trigger errors in reclaim or during page free such as in the
      following oops

      The fix is straight-forward.  isolate_migratepages() has to make a
      similar check to isolate_freepage to ensure that it never isolates pages
      from a zone it does not hold the LRU lock for.
      
      This was discovered in a 3.0-based kernel but it affects 3.1.x, 3.2.x
      and current mainline.

      nilfs2: avoid overflowing segment numbers in nilfs_ioctl_clean_segments() · 1ecd3c7e
      Xi Wang authored
      nsegs is read from userspace.  Limit its value and avoid overflowing nsegs
      * sizeof(__u64) in the subsequent call to memdup_user().
      
      This patch complements 481fe17e ("nilfs2: potential integer overflow
      in nilfs_ioctl_clean_segments()").

      arch: fix ioport mapping on mips,sh
      
      Kevin Cernekee reported that recent cleanup that replaced pci_iomap with
      a generic function failed to take into account the differences in io
      port handling on mips and sh architectures.
      
      Rather than revert the changes reintroducing the code duplication, this
      patchset fixes this by adding ability for architectures to override
      ioport mapping for pci devices.
