Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument,
when all it needs is a boolean pointer.

It would be better to update this API to make it accept 'bool *'
instead, as that will make it more consistent and often more convenient.
Over that bool takes just a byte.

That required updates to all user sites as well, in the same commit
updating the API. regmap core was also using
debugfs_{read|write}_file_bool(), directly and variable types were
updated for that to be bool as well.

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}

@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};
</smpl>

The default llseek operation is changing from
default_llseek to no_llseek, so all code relying on
the current behaviour needs to make that explicit.

The wireless driver infrastructure and some of the drivers
make use of generated debugfs files, so they cannot
be converted by our script that automatically determines
the right operation.

All these files use debugfs and they typically rely
on simple_read_from_buffer, so the best llseek operation
here is generic_file_llseek.

This adds support for verbose runtime statistics.
It defaults to off and must be enabled in debugfs, if desired.
The first measurement may be incorrect, because statistics are not cleared
after they got enabled through debugfs.

Use a threaded IRQ handler to allow locking the mutex and
sleeping while executing an interrupt.
This removes usage of the irq_lock spinlock, but introduces
a new hardirq_lock, which is _only_ used for the PCI/SSB lowlevel
hard-irq handler. Sleeping busses (SDIO) will use mutex instead.

Dynamically control the log verbosity with a module parameter.
This enables us to dynamically enable debugging messages (or disable
info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.

This increases the module size by about 3k. But in practice it reduces the
module size for the user, because some distributions ship the b43 module
with CONFIG_B43_DEBUG set, which increases the module by about 15k.

So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
There is no reason to keep it in a production-release kernel.
So we have a net reduction in size by about 12k.

This patch also adds a printk of the wireless core revision, so people
don't have to enable SSB debugging to get the wireless core revision.
