CONFIG_GENERIC_BUG. This is needed for BUGFLAG_WARNING usage.

The CPU family abstraction already exists, so move out the PXSEG
definition for each one. SH-2A already has this special cased,
and SH-5 will as well.

This fixes vio_find_name() in arch/powerpc/kernel/vio.c, which is
currently broken because it tries to use devices_subsys. That is bad
for two reasons: (1) it's doing (or trying to do) a scan of all
devices when it should only be scanning those on the vio bus, and
(2) devices_subsys was an internal symbol of the device system code
which was never meant for external use and has now gone away, and
thus the kernel fails to compile on pSeries.
The new version uses bus_find_device_by_name() on the vio bus
(vio_bus_type).

The driver core, and some other parts of the kernel just want to find a
device based on a name for a specific bus. Give them a simple wrapper
to prevent them from having to always roll their own.
This will be used in the PPC patch later in this series.

When trying to load a module with the same name as a built-in one, a
scary kobject backtrace comes up. Prevent that from checking for this
condition and warning the user as to what exactly is going on.

This problem is due to the kobject rework recently done in this file.
The mce_amd_64.c code uses some wierd forward calls to back out of the
recursive way the code creates kobjects. Because of this, we need to
verify that we have really created a kobject before calling
kobject_uevent().
Many thanks to Yinghai Lu <yhlu.kernel@gmail.com> for reporting the
problem and testing.

Add the ability to find a device node by just what its compatible with.
This is useful in cases that we don't have a prop to find the node with.

The common arch/powerpc code calls in to functions in setup-bus.c
so some builds of ppc32 would fail.
Note, ppc32 usage of setup-irq.c is limited to arch/ppc and should be
removed when arch/ppc goes away.

On the at92sam9263ek board, tell the input subsystem about the buttons.
This patch is taken from Andrew Victor's at91 patchset, then updated to
match the latest kernel code and to use labels printed on the board.
Also update the at91sam9261ek buttons to cope with input changes.

Zero-bytes transfers would leave the bus transaction unfinished
(no i2c stop is sent), with the following transfer actually
sending the slave address to the previously addressed device,
resulting in weird device failures (e.g. reset minute register
values in my RTC).
This patch instructs the controller to send an I2C STOP right after
the slave address in case of a zero-byte transfer.
