This allows for proper console unregistration via the VT layer, and updates
the FB layer to use it. This makes debugging new console drivers much easier,
since you can properly clean them up before unloading.
[adaplas]
unregister_framebuffer() is typically called as part of the driver's
module_exit(). Doing so otherwise will freeze the machine as the VT layer is
holding reference counts on fbcon, and fbcon on the driver. With this change,
it allows unregister_framebuffer() to be called safely anywhere as needed.
Additions from the original: If multiple drivers are used by fbcon, and if
one of them unregisters, a driver will take over the consoles vacated by the
outgoing one (via set_con2fb_map). Once only the outgoing driver remains,
then fbcon will unbind from the VT layer (if CONFIG_HW_CONSOLE_UNBINDING is
set to y).
It is important that these drivers implement fb_open() and fb_release()
just to ensure that no other process is using the driver. Likewise, these
drivers _must_ check the return value of unregister_framebuffer().

Allow fbcon to select the primary display adapter using the
fb_is_primary_device() arch-specific helper. If a a primary adapter is
detected, fbcon will unbind the old adapter from the VT layer, then rebind
using the new adapter. This requires that bind_/unbind_con_driver() be made
public.
Because this feature may produce unexpected behavior (from the user's POV),
this must be explicitly enabled in Kconfig.

This updates the rtc-ds1307 driver so that converting it to a "new style"
driver (driver model, not legacy i2c model) will involve fewer changes.
- Use pointer to i2c_client almost everywhere, so that it's easy
to let the i2c core create that object;
- Avoid using i2c_client.adapter, since that field is redundant and
thus may go away (same object as i2c_client.dev.parent).
- Extend type enum to include various RTCs this is expected to
work with, and include register support for them.
It also cleans up the support for multiple chip types, and fixes a
glitch that could appear with an un-initialized RTC.

drivers/isdn/capi/capi.c:552: warning: cast from pointer to integer of different size
Of course, the code here might actually be buggy, in which case this patch
should not be applied?
Answer:
No this field is ignored inside linux kernel.Yes this is ugly, but it's
the CAPI spec for all OS.
CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which
represent the 32 bit buffer address of the payload data. In linux the
payload data do not use a sperate buffer, data follows directely after the
CAPI Message in the same skb and we use this assumption inside the drivers,
so we can ignore this field.
Inside the linux CAPI implemetation we never use this field, so it could
also have no value, but since random data in a message is bad as well (e.g.
displayed in CAPI traces) we set is to the most adequate value.
Outside the kernel the capi20 library sets the correct addresses (there is
an optional second field for 64 bit adresses for 64 bit systems, we do not
use here).

Tweak Kconfig for the S3C24XX SPI controller drivers. Both use the bitbang
framework; only one previously said that. Plus in this case "select" is
the right way to manage that dependency, since folk will not know up front
to enable bitbang in order to even see those S3C drivers in order to enable
them.

Update chipselect handling for atmel_spi:
* Teach it how to leave chipselect active between messages; this
helps various drivers work better.
* Cope with at91rm0200 errata: nCS0 can't be managed with GPIOs.
The MR.PCS value is now updated whenever a chipselect changes.
(This requires SPI pinmux init for that controller to change,
and also testing on rm9200; doesn't break at91sam9 or avr32.)
* Fix minor glitches: spi_setup() must leave chipselects inactive,
as must removal of the spi_device.
Also tweak diagnostic messaging to be a bit more useful.

Minor updates to atmel_spi:
- DMA:
* Comments to explain the DMA policies
* Report any mapping errors from spi_transfer()
* Remove extra loop for DMA mapping
- Diagnostics: report minimum clock rate, if we need to reject a
spi_setup() request because that rate is too low.

The MPC83xx SPI controller clock divider can divide the system clock by not
more then 1024. The spi_mpc83xx driver does not check this and silently
writes garbage to the SPI controller registers when asked to run at lower
frequencies. I've tried to run the SPI on a 266MHz MPC8349E with 100kHz
for debugging a bus problem and suddenly was confronted with a 2nd problem
to debug.. ;-)
The patch adds an additional check which avoids writing garbage to the SPI
controller registers and warn the user about it. This might help others to
avoid simmilar problems.

Get rid of annoying GCC warning on 32-bit platforms.

drivers/spi/spidev.c:184: warning: cast to pointer from integer of different size
drivers/spi/spidev.c:216: warning: cast to pointer from integer of different size
The trick is to add an extra cast using "ptrdiff_t" to convert the u64 to

Minor SPI controller driver updates: make the setup() methods reject
spi->mode bits they don't support, by masking aginst the inverse of bits
they *do* support. This insures against misbehavior later when new mode
bits get added.
Most controllers can't support SPI_LSB_FIRST; more handle SPI_CS_HIGH.
Support for all four SPI clock/transfer modes is routine.

This is a driver for the SB1250 DUART, a dual serial port implementation
included in the Broadcom family of SOCs descending from the SiByte SB1250
MIPS64 chip multiprocessor. It is a new implementation replacing the
old-fashioned driver currently present in the linux-mips.org tree. It
supports all the usual features one would expect from a(n asynchronous)
serial driver, including modem line control (as far as hardware supports it
-- there is edge detection logic missing from the DCD and RI lines and the
driver does not implement polling of these lines at the moment), the serial
console, BREAK transmission and reception, including the magic SysRq. The
receive FIFO threshold is not maintained though.
The driver was tested with a SWARM board which uses a BCM1250 SOC (which is
dual MIPS64 CMP) and has both ports of the single DUART implemented wired
externally. Both were tested. Testing included using the ports as
terminal lines at 1200bps (which is the ports minimum), 115200bps and a
couple of random speeds inbetween. The modem lines were verified to
operate correctly. No testing was performed with a use as a network
interface, like with SLIP or PPP.

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.
