bf6aede712 workqueue: add to_delayed_work() helper function
It is a fairly common operation to have a pointer to a work and to need a
pointer to the delayed work it is contained in.  In particular, all
delayed works which want to rearm themselves will have to do that.  So it
would seem fair to offer a helper function for this operation.

99b7623380 proc 2/2: remove struct proc_dir_entry::owner
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.

We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.

But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.

->read_proc/->write_proc were just fixed to not require ->owner for
protection.

rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.

Removing ->owner will also make PDE smaller.

So, let's nuke it.

Kudos to Jeff Layton for reminding about this, let's say, oversight.

60aa49243d Rationalize fasync return values
Most fasync implementations do something like:

     return fasync_helper(...);

But fasync_helper() will return a positive value at times - a feature used
in at least one place.  Thus, a number of other drivers do:

     err = fasync_helper(...);
     if (err < 0)
             return err;
     return 0;

In the interests of consistency and more concise code, it makes sense to
map positive return values onto zero where ->fasync() is called.

d9bdffd210 Input: add driver for S1 button of rb532
Mikrotik's Routerboard 532 has two builtin buttons, from which one
triggers a hardware reset. The other one is accessible through GPIO
pin 1. Sadly, this pin is being multiplexed with UART0 input, so
enabling it as interrupt source (as implied by the gpio-keys driver)
is not possible unless UART0 has been turned off. The later one though
is a rather bad idea as the Routerboard is an embedded device with
only a single serial port, so it's almost always used as serial
console device.

This patch adds a driver based on INPUT_POLLDEV, which disables the
UART and reconfigures GPIO pin 1 temporarily while reading the button
state.  This procedure works fine and has been tested as part of
another, unpublished driver for this device.

The remaining registers are separated into:

   - <mach/regs-ost.h>
   - <mach/regs-rtc.h>
   - <mach/regs-intc.h>

and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:

1. include the specific <mach/regs-*.h> with care (if that's absolutely
   necessary)

2. define the registers in the driver, make cleanly defined API to expose
   the register access to external with sufficient reason

On parisc machines, which don't have HIL, removing the hilkbd module

A few functions were renamed to clean up the code and make it easier

Disable the MODULE_DEVICE_TABLE() macro on parisc since the kernel
module autoloader should instead prefer the hp_sdc driver which takes

and writes as well as generally improving the quality of the code and
supporting concurrency (all needed to support the Dreamcast visual
memory unit - a driver will also be posted for that).

Changes in the bus driver necessitate some changes in the two maple bus
input drivers that are currently in mainline.

As well as supporting block reads and writes this code clean up removes
some poor handling of locks, uses an atomic status variable to serialise
access to devices and more robusly handles the general performance
problems of the bus.

With a postfix decrement timeleft reaches -1 rather than 0,
but after the loop it is tested to have become 0.

8a49cfa9de Input: ati_remote2 - check module params
Validate that the values of the module parameters are within the
supported range. Also print the values in hex since that seems like
a better match for bitmasks than decimal.

d329e33c7c Input: ati_remote2 - add per device attrs
Add per device channel_mask and mode_mask attributes. They inherit
the values from the module parameters when the device is registered.
One additional benefit is that now runtime changes to channel_mask
can actually affect the hardware channel setup like they should.
