Make kernel-doc warn when a function/struct/union/typedef does not contain
a properly formatted short description, such as:
 * scsi_devinfo: set up the dynamic device list
or
 * scsi_devinfo -

This warning is only generated when verbose (-v) mode is used.

Also explain the -v command line option in the -h output.

Rename old vfs_ioctl to do_ioctl, because the comment above it clearly
indicates that it is an internal function not to be exported to modules;
therefore it should have a more traditional do_XXX name.  The new do_ioctl
is exported in fs.h but not to modules.

Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should
preferably be reserved to callable VFS functions which modules may call, as
many other vfs_XXX functions already do.  Export the new vfs_ioctl to GPL
modules so others can use it (including Unionfs and eCryptfs).  Add DocBook
for new vfs_ioctl.

The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active
high) from IRQ settings.  There are devices that have IAS=0 but still need
the IRQ to trigger on a rising edge.  With this patch, machines with DS1WM
that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data.

    power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL

Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs
attributes with one more entry than the number of enums in power_supply.h.
This leads to some attributes containing the value of the attribute right
after it.  For example, temp_ambient would have the value of
time_to_empty_now.  In my case, I had time_to_full_avg have the value which
should be in model_name, when the former was usually empty.

This merges the mux.c (including the connection interface) with trans_fd

to be rewritten to clean it up and simplify the implementation, but this

Just cleaning up patches for 2.6.25 merge, and noticed that

When booting from v9fs, down_interruptible in p9_idpool_get() triggered a BUG
as it was being called with IRQs disabled.  A spinlock seems like the right
thing to be using since the idr functions go out of their way not to sleep.

This patch eliminates the BUG by converting the semaphore to a spinlock.
