The current <linux/debugfs.h> include file is a little fragile in that
it is not self-contained and hence may cause compile warnings or
errors depending on the files included before it, the kernel config
and the architecture. This patch makes things a little more robust by:
- including <linux/types.h> to get definitions of u32, mode_t, and so on.
- forward declaring struct file_operations.
- including <linux/err.h> when CONFIG_DEBUG_FS is not set
The last change is particularly useful, as a kernel developer is
likely to build with debugfs always enabled and never see the build
breakage cased if debugfs is disabled.

This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

The current problem seen is that the queue lock is actually in the
SCSI device structure, so when that structure is freed on device
release, we go boom if the queue tries to access the lock again.
The fix here is to move the lock from the scsi_device to the queue.

gcc-4 warns with
include/linux/cpuset.h:21: warning: type qualifiers ignored on function
return type
cpuset_cpus_allowed is declared with const
extern const cpumask_t cpuset_cpus_allowed(const struct task_struct *p);
First const should be __attribute__((const)), but the gcc manual
explains that:
"Note that a function that has pointer arguments and examines the data
pointed to must not be declared const. Likewise, a function that calls a
non-const function usually must not be const. It does not make sense for
a const function to return void."
The following patch remove const from the function declaration.

These have been deprecated since ->compat_ioctl when in, thus only a short
deprecation period. There's four users left: i2o_config, s390/z90crypy,

submitted to get rid of it.

This was unexported by Arjan because we have no current users.
However, during a conversion from tasklets to workqueues of the parisc led
functions, we ran across a case where this was needed. In particular, the
open coded equivalent of cancel_rearming_delayed_workqueue was implemented
incorrectly, which is, I think, all the evidence necessary that this is a
useful API.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
