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.

The naming of the constant defined for PCI ID 1022:7450 does not seem
to match the information at http://pciids.sourceforge.net/:

	http://pci-ids.ucw.cz/iii/?i=1022

There 1022:7450 is listed as "AMD-8131 PCI-X Bridge" while 1022:7451
is listed as "AMD-8131 PCI-X IOAPIC".  Yet, the current definition for
0x7450 is PCI_DEVICE_ID_AMD_8131_APIC.	It seems to me like that name
should map to 0x7451, while a name like PCI_DEVICE_ID_AMD_8131_BRIDGE
should map to 0x7450.

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.

The manual driver <-> device binding attribute in sysfs doesn't return
the correct value on failure or success of driver_probe_device.
driver_probe_device returns 1 on success (the driver accepted the
device) or 0 on probe failure (when the driver didn't accept the
device but no real error occured). However, the attribute can't just
return 0 or 1, it must return the number of bytes consumed from buf
or an error value. Returning 0 indicates to userspace that nothing
was written (even though the kernel has tried to do the bind/probe and
failed). Returning 1 indicates that only one character was accepted in
which case userspace will re-try the write with a partial string.

A more correct version of driver_bind would return count (to indicate
the entire string was consumed) when driver_probe_device returns 1
and -ENODEV when driver_probe_device returns 0. This patch makes that
change.

This patch (as667) changes the __device_release_driver() routine to
prevent it from crashing when it runs across a device not on any bus.

It works like this:
  Open the file
  Read all the contents.
  Call poll requesting POLLERR or POLLPRI (so select/exceptfds works)
  When poll returns,
     close the file and go to top of loop.
   or lseek to start of file and go back to the 'read'.

Events are signaled by an object manager calling
   sysfs_notify(kobj, dir, attr);

If the dir is non-NULL, it is used to find a subdirectory which
contains the attribute (presumably created by sysfs_create_group).

This has a cost of one int  per attribute, one wait_queuehead per kobject,
one int per open file.

The name "sysfs_notify" may be confused with the inotify
functionality.  Maybe it would be nice to support inotify for sysfs
attributes as well?

This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action
to be pollable

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.

Previously, scatterlist tests didn't write patterned data.  Given how many
corner cases are addresed by them, this was a significant gap in Linux-USB
test coverage.  Moreover, when peripherals checked for correct data patterns,
false error reports would drown out the true ones.

This adds the pattern on the way OUT from the host, so scatterlist tests can
now be used to uncover bugs like host TX or peripheral RX paths failing for
back-to-back short packets.  It's easy enough to get an error there with at
least one of the {DMA,PIO}{RX,TX} code paths, or run into hardware races
that need to be defended against.

Note this patch doesn't add checking for correct data patterns on the way
IN from peripherals, just a FIXME for later.
