      USB: Don't fail USB3 probe on missing legacy PCI IRQ. · 68d07f64
      Sarah Sharp authored
      Intel has a PCI USB xhci host controller on a new platform. It doesn't
      have a line IRQ definition in BIOS.  The Linux driver refuses to
      initialize this controller, but Windows works well because it only depends
      on MSI.
      
      Actually, Linux also can work for MSI.  This patch avoids the line IRQ
      checking for USB3 HCDs in usb core PCI probe.  It allows the xHCI driver
      to try to enable MSI or MSI-X first.  It will fail the probe if MSI
      enabling failed and there's no legacy PCI IRQ.
      
      This patch should be backported to kernels as old as 2.6.32.

      xhci: Fix oops caused by more USB2 ports than USB3 ports. · 3278a55a
      Sarah Sharp authored
      The code to set the device removable bits in the USB 2.0 roothub
      descriptor was accidentally looking at the USB 3.0 port registers
      instead of the USB 2.0 registers.  This can cause an oops if there are
      more USB 2.0 registers than USB 3.0 registers.
      
      This should be backported to kernels as old as 2.6.39, that contain the
      commit 4bbb0ace "xhci: Return a USB 3.0
      hub descriptor for USB3 roothub."

      USB: Remove duplicate USB 3.0 hub feature #defines. · d9f5343e
      Sarah Sharp authored
      Somehow we ended up with duplicate hub feature #defines in ch11.h.
      Tatyana Brokhman first created the USB 3.0 hub feature macros in 2.6.38
      with commit 0eadcc09 "usb: USB3.0 ch11
      definitions".  In 2.6.39, I modified a patch from John Youn that added
      similar macros in a different place in the same file, and committed
      dbe79bbe "USB 3.0 Hub Changes".
      
      Some of the #defines used different names for the same values.  Others
      used exactly the same names with the same values, like these gems:
      
       #define USB_PORT_FEAT_BH_PORT_RESET     28
      ...
       #define USB_PORT_FEAT_BH_PORT_RESET            28
      
      According to my very geeky husband (who looked it up in the C99 spec),
      it is allowed to have object-like macros with duplicate names as long as
      the replacement list is exactly the same.  However, he recalled that
      some compilers will give warnings when they find duplicate macros.  It's
      probably best to remove the duplicates in the stable tree, so that the
      code compiles for everyone.
      
      The macros are now fixed to move the feature requests that are specific
      to USB 3.0 hubs into a new section (out of the USB 2.0 hub feature
      section), and use the most common macro name.
      
      This patch should be backported to 2.6.39.

      Reduce the number of expensive division instructions done by _parse_integer() · 690d137f
      David Howells authored
      _parse_integer() does one or two division instructions (which are slow)
      per digit parsed to perform the overflow check.
      
      Furthermore, these are particularly expensive examples of division
      instruction as the number of clock cycles required to complete them may
      go up with the position of the most significant set bit in the dividend:
      
      	if (*res > div_u64(ULLONG_MAX - val, base))
      
      which is as maximal as possible.
      
      Worse, on 32-bit arches, more than one of these division instructions
      may be required per digit.
      
      So, assuming we don't support a base of more than 16, skip the check if the
      top nibble of the result is not set at this point.

      [ Changed it to not dereference the pointer all the time - even if the
        compiler can and does optimize it away, the code just looks cleaner.
        And edited the top nybble test slightly to make the code generated on
        x86-64 better in the loop - test against a hoisted constant instead of
        shifting and testing the result ]

      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));

      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:

      Fix CONFIG_TRANSPARENT_HUGEPAGE=y CONFIG_SMP=n CONFIG_DEBUG_VM=y
      CONFIG_DEBUG_SPINLOCK=n kernel: spin_is_locked() is then always false,
      and so triggers some BUGs in Transparent HugePage codepaths.
      
      asm-generic/bug.h mentions this problem, and provides a WARN_ON_SMP(x);
      but being too lazy to add VM_BUG_ON_SMP, BUG_ON_SMP, WARN_ON_SMP_ONCE,
      VM_WARN_ON_SMP_ONCE, just test NR_CPUS != 1 in the existing VM_BUG_ONs.

      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 "X" in the taint flag means that external modules were loaded but but
      is unrelated to the bug triggering.  The real problem was because the PFN
      layout looks like this
      
        Zone PFN ranges:
          DMA      0x00000010 -> 0x00001000
          DMA32    0x00001000 -> 0x00100000
          Normal   0x00100000 -> 0x01e80000
        Movable zone start PFN for each node
        early_node_map[14] active PFN ranges
            0: 0x00000010 -> 0x0000009b
            0: 0x00000100 -> 0x0007a1ec
            0: 0x0007a354 -> 0x0007a379
            0: 0x0007f7ff -> 0x0007f800
            0: 0x00100000 -> 0x00680000
            1: 0x00680000 -> 0x00e80000
            0: 0x00e80000 -> 0x01080000
            1: 0x01080000 -> 0x01280000
            0: 0x01280000 -> 0x01480000
            1: 0x01480000 -> 0x01680000
            0: 0x01680000 -> 0x01880000
            1: 0x01880000 -> 0x01a80000
            0: 0x01a80000 -> 0x01c80000
            1: 0x01c80000 -> 0x01e80000
      
      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.

      nsegs is read from userspace.  Limit its value and avoid overflowing nsegs
      * sizeof(__u64) in the subsequent call to memdup_user().
