kfifo: move struct kfifo in place
This is a new generic kernel FIFO implementation.
The current kernel fifo API is not very widely used, because it has to
many constrains. Only 17 files in the current 2.6.31-rc5 used it.
FIFO's are like list's a very basic thing and a kfifo API which handles
the most use case would save a lot of development time and memory
resources.
I think this are the reasons why kfifo is not in use:
- The API is to simple, important functions are missing
- A fifo can be only allocated dynamically
- There is a requirement of a spinlock whether you need it or not
- There is no support for data records inside a fifo
So I decided to extend the kfifo in a more generic way without blowing up
the API to much. The new API has the following benefits:
- Generic usage: For kernel internal use and/or device driver.
- Provide an API for the most use case.
- Slim API: The whole API provides 25 functions.
- Linux style habit.
- DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros
- Direct copy_to_user from the fifo and copy_from_user into the fifo.
- The kfifo itself is an in place member of the using data structure, this save an
indirection access and does not waste the kernel allocator.
- Lockless access: if only one reader and one writer is active on the fifo,
which is the common use case, no additional locking is necessary.
- Remove spinlock - give the user the freedom of choice what kind of locking to use if
one is required.
- Ability to handle records. Three type of records are supported:
- Variable length records between 0-255 bytes, with a record size
field of 1 bytes.
- Variable length records between 0-65535 bytes, with a record size
field of 2 bytes.
- Fixed size records, which no record size field.
- Preserve memory resource.
- Performance!
- Easy to use!
This patch:
Since most users want to have the kfifo as part of another object,
reorganize the code to allow including struct kfifo in another data
structure. This requires changing the kfifo_alloc and kfifo_init
prototypes so that we pass an existing kfifo pointer into them. This
patch changes the implementation and all existing users.

platform/x86: fujitsu-laptop: track the last instantiated FUJ02E3 ACPI device
fujitsu-laptop registers two ACPI drivers: one for ACPI device FUJ02B1
enabling backlight control and another for ACPI device FUJ02E3 which
handles various other stuff (hotkeys, LEDs, etc.) In a perfect world,
private data used by each of these drivers would be neatly encapsulated
in a structure specific to a given driver instance. Sadly, firmware
present on some Fujitsu laptops makes that impossible by exposing
backlight power control (which is what the FUJ02B1 ACPI device should
take care of) through the FUJ02E3 ACPI device. This means the backlight
driver needs a way to access an ACPI device it is not bound to. When
the backlight driver is extracted into a separate module, it will not be
able to rely on a module-wide variable any more and such access will
happen through an API exposed by fujitsu-laptop.
For all known firmwares out in the wild, it seems that whenever the
FUJ02B1 ACPI device is present, it is always accompanied by a single
instance of the FUJ02E3 ACPI device. We could independently grab an
ACPI handle to the FUJ02E3 ACPI device from the backlight driver, but
that would require using a hardcoded absolute path to that ACPI device,
which is subject to change. It is easier to simply store a module-wide
pointer to the last (most likely only) FUJ02E3 ACPI device found, make
the aforementioned API use it and cover our bases by warning the user if
firmware exposes multiple FUJ02E3 ACPI devices.
Introducing this pointer in advance allows us to get rid of the
acpi_handle field of struct fujitsu_bl and also enables a bit more
step-by-step migration to a device-specific implementation of
call_fext_func().

platform/x86: fujitsu-laptop: track the last instantiated FUJ02E3 ACPI device
fujitsu-laptop registers two ACPI drivers: one for ACPI device FUJ02B1
enabling backlight control and another for ACPI device FUJ02E3 which
handles various other stuff (hotkeys, LEDs, etc.) In a perfect world,
private data used by each of these drivers would be neatly encapsulated
in a structure specific to a given driver instance. Sadly, firmware
present on some Fujitsu laptops makes that impossible by exposing
backlight power control (which is what the FUJ02B1 ACPI device should
take care of) through the FUJ02E3 ACPI device. This means the backlight
driver needs a way to access an ACPI device it is not bound to. When
the backlight driver is extracted into a separate module, it will not be
able to rely on a module-wide variable any more and such access will
happen through an API exposed by fujitsu-laptop.
For all known firmwares out in the wild, it seems that whenever the
FUJ02B1 ACPI device is present, it is always accompanied by a single
instance of the FUJ02E3 ACPI device. We could independently grab an
ACPI handle to the FUJ02E3 ACPI device from the backlight driver, but
that would require using a hardcoded absolute path to that ACPI device,
which is subject to change. It is easier to simply store a module-wide
pointer to the last (most likely only) FUJ02E3 ACPI device found, make
the aforementioned API use it and cover our bases by warning the user if
firmware exposes multiple FUJ02E3 ACPI devices.
Introducing this pointer in advance allows us to get rid of the
acpi_handle field of struct fujitsu_bl and also enables a bit more
step-by-step migration to a device-specific implementation of
call_fext_func().
