mtdblock is the only user of aggregate capabilities in mtd.  This is clearly
bogus and should be changed.  In particular, it tries to determine whether
the device in question is a piece of RAM.  For every single driver that fits
the current criteria, an easier test would be to check for the type being
MTD_RAM.

For a while now, we've postponed CRC-checking of data nodes to be done
by the GC thread, instead of being done while the user is waiting for
mount to finish. The GC thread would iterate through all the inodes on
the system and check each of their data nodes. It would skip over inodes
which had already been used or were already being read in by
read_inode(), because their data nodes would have been examined anyway.

However, we could sometimes reach the end of the for-each-inode loop and
still have some unchecked space left, if an inode we'd skipped was
_still_ in the process of being read. This fixes that race by actually
waiting for read_inode() to finish rather than just moving on.

Thanks to Ladislav Michl for coming up with a reproducible test case and
helping to track it down.

      [PATCH] i2c-parport: Make type parameter mandatory
      
      This patch forces the user to specify what type of adapter is present when
      loading i2c-parport or i2c-parport-light.  If none is specified, the driver
      init simply fails - instead of assuming adapter type 0.
      
      This alleviates the sometimes lengthy boot time delays which can be caused
      by accidentally building one of these into a kernel along with several i2c
      slave drivers that have lengthy probe routines (e.g. hwmon drivers).
      
      Kconfig and documentation updated accordingly.

      [PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/
      
      dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64.
      Currently all three arches compile it from arch/i386, which means that ia64
      and x86_64 depend on things in arch/i386 that they wouldn't otherwise care
      about.
      
      This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing
      trailing whitespace) and the associated Makefile changes.  All three
      architectures already set CONFIG_DMI in their top-level Kconfig files.

If Classical IP over ATM module is loaded, its neighbor table gets
populated when permanent neighbor entries are created; but these entries
are not flushed when the device is removed. Since the entry never gets
flushed the unregister of the network device never completes.

This version of the patch also adds locking around the reference to
the atm arp daemon to avoid races with events and daemon state changes.
(Note: barrier() was never really safe)

This updates the DMA API documentation to address a few issues:

 - The dma_map_sg() call results are used like pci_map_sg() results:
   using sg_dma_address() and sg_dma_len().  That's not wholly obvious
   to folk reading _only_ the "new" DMA-API.txt writeup.

 - Buffers allocated by dma_alloc_coherent() may not be completely
   free of coherency concerns ... some CPUs also have write buffers
   that may need to be flushed.

 - Cacheline coherence issues are now mentioned as being among issues
   which affect dma buffers, and complicate/prevent using of static and
   (especially) stack based buffers with the DMA calls.

I don't think many drivers currently need to worry about flushing write
buffers, but I did hit it with one SOC using external SDRAM for DMA
descriptors:  without explicit writebuffer flushing, the on-chip DMA
controller accessed descriptors before the CPU completed the writes.

I use 2.6.15.6 Linux kernel and found some problems. I have about 100
Linux boxes (all with the same (binary the same) kernel). Last time I have
upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2,
.4 and .6) and I have found some problems on VIA based PC's. Probably the
reason of this is that some VIA chipsets are unrecognized by IRQ router.

In line 586 there is: /* FIXME: add new ones for 8233/5 */

There were only a few of chipsets ID's there, some of my VIA chipsets were
not present and kernel used default IRQ router.

I have added three entries, so that the code looks like:

        case PCI_DEVICE_ID_VIA_82C596:
        case PCI_DEVICE_ID_VIA_82C686:
        case PCI_DEVICE_ID_VIA_8231:
        case PCI_DEVICE_ID_VIA_8233A:
        case PCI_DEVICE_ID_VIA_8235:
        case PCI_DEVICE_ID_VIA_8237:
        case PCI_DEVICE_ID_VIA_8237_SATA:
                /* FIXME: add new ones for 8233/5 */
                r->name = "VIA";
                r->get = pirq_via_get;
                r->set = pirq_via_set;
                return 1;
        }

The kernel goes fine but I haven't testes it for weeks, I'm just a moment
after reboot :)
One thing is different (better?):
Using previus kernel I had:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0
now I have:
PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11

Maybe it is good idea to add there some more VIA chipsets?
The ones I have added seem to be OK.

The init function for the RPA PCI Hotplug driver returns -ENODEV in the
case that no hotplug-capable slots are detected in the system.  This is
bad, since hot-capable slots can be added after boot to a purely virtual
POWER partition.  This is also bad because DLPAR I/O operations depend
on the rpaphp module.

Change the rpaphp init module to return success for the case of
partitions that own no hotplug-capable slots at boot.  Such slots can be
dynamically added after boot.
