cgroupfs: create /sys/fs/cgroup to mount cgroupfs on

We really shouldn't be asking userspace to create new root filesystems.
So follow along with all of the other in-kernel filesystems, and provide
a mount point in sysfs.

For cgroupfs, this should be in /sys/fs/cgroup/  This change provides
that mount point when the cgroup filesystem is registered in the kernel.

Driver core: Add BUS_NOTIFY_BIND_DRIVER

Add BUS_NOTIFY_BIND_DRIVER as a bus notifier event.

For driver binding/unbinding we with this in
place have the following bus notifier events:
 - BUS_NOTIFY_BIND_DRIVER - before ->probe()
 - BUS_NOTIFY_BOUND_DRIVER - after ->probe()
 - BUS_NOTIFY_UNBIND_DRIVER - before ->remove()
 - BUS_NOTIFY_UNBOUND_DRIVER - after ->remove()

The event BUS_NOTIFY_BIND_DRIVER allows bus code
to be notified that ->probe() is about to be called.

Useful for bus code that needs to setup hardware before
the driver gets to run. With this in place platform
drivers can be loaded and unloaded as modules and the
new BIND event allows bus code to control for instance
device clocks that must be enabled before the driver
can be executed.

Without this patch there is no way for the bus code to
get notified that a modular driver is about to be probed.

Driver core: Drop __must_check from bus_for_each_drv()

There is little rationale for marking bus_for_each_drv() __must_check.
It is more of an iteration helper than a real function. You don't know
in advance which callback it will be used on, so you have no clue how
important it can be to check the returned value. In practice, this
helper function can be used for best-effort tasks.

As a matter of fact, bus_for_each_dev() is not marked __must_check.
So remove it from bus_for_each_drv() as well. This is the same that
was done back in October 2006 by Russell King for

MIPS: Clean up notify_die() usage.

The sixth argument of notify_die() is a signal number, the fifth is a
trap number.

Instead of passing a signal number in a randomly selected argument,
pass it in the sixth.  Extract the exception code from regs and pass
that as the trap number.

Get rid of redundant cast, and remove some gratuitous spaces.

Nobody actually does anything with the signal number or trap number,
but we might as well populate them with sensible values.

a JZ4740 SoC.

MIPS: Octeon: HOTPLUG_CPU fixes.

* Rename camel-case InitTLBStart_addr to octeon_bootloader_entry_addr.

* Convert calls to cvmx_read64_uint32(), to simple pointer
  dereferences.

* Set proper ebase.

* Don't confuse coreid and cpu numbers.

* Try to maintain consistent bootloader coremask.

* Update the signature and boot_init_vector of supported bootloaders.

MIPS: Octeon: Make MSI use handle_simple_irq().

The use of handle_percpu_irq() is not really what we want for MSI, use
handle_simple_irq() instead.  This is probably the prototypical case
for using handle_simple_irq(), because all the MSIs are dispatched from
the root interrupt service routine.

Also since the base IRQ is not shared, don't pass IRQF_SHARED.

MIPS: Octeon: Fix fixup_irqs for HOTPLUG_CPU

The original version went behind the back of everything, leaving
things in an inconsistent state.

Now we use the irq_set_affinity() to do the work for us.  This has the
advantage that the IRQ core's view of the affinity stays consistent.

MIPS: Octeon: Improve interrupt handling.

The main change is to change most of the IRQs from handle_percpu_irq
to handle_fasteoi_irq.  This necessitates extracting all the .ack code
to common functions that are not exposed to the irq core.

The affinity code now acts more sanely, by doing round-robin
distribution instead of broadcasting.

Because of the change to handle_fasteoi_irq and affinity, some of the
IRQs had to be split into separate groups with their own struct
irq_chip to prevent undefined operations on specific IRQ lines.

MIPS: au1000_eth: Get ethernet address from platform_data

au1000_eth uses firmware calls to get a valid MAC address, and changes
it depending on platform device id.  This patch moves this logic out of
the driver into the platform device registration part, where boards with
supported chips can use whatever firmware interface they need; the default
implementation maintains compatibility with existing, YAMON-based firmware.

This one depends on a previous patch (which removes SOC_AU1X00 and changes
MACH_ALCHEMY) to apply cleanly (and then actually work), so I'd love for
this to go in via the mips tree.
