The Cell Broadband Engine contains a 64-bit PowerPC core with 2 hardware
threads (called PPEs) and 8 Synergistic Processing Engines (called SPEs).
When booting Linux, 2 penguins logos are shown on the graphical console by
the standard frame buffer console logo code.
To emphasize the existence of the SPEs (which can be used under Linux), we
added a second row of (smaller) helper penguin logos, one for each SPE.

VGA console driver can misunderstand the current mode(Text/Graphic) under
"disable console blanking" setting. When "disable console blank" is set
(blankinterval=0), "do_unblank_screen()" function returns without changing
"blank_state", and when "blank_state" is "blank_off", "do_blank_screen()
function returns without invoking sw->con_blank() function. That's why VGA
console driver can misunderstand the current mode.

The SH board that was the only user for this code was removed entirely from
the kernel quite some time ago, so there's no reason to leave the stubs in
place. Additionally this driver was completely broken anyways, so there's
not really a lot of point in fixing it up either.
I can't imagine that this driver gets any testing on ARM either, given that
FB_BLANK_UNBLANKING doesn't exist, and kills the build regardless of which
platform is compiling. This fixes that, too.
It wouldn't be a lot of work to finish the platform device conversion and
go with a generic 8-bit read/write_reg and kill off the architecture
dependence completely, should someone have any use for this driver.

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().

set_con2fb_map() has regressed for some time. Using fbcon=map:01, for
example, works only if there is only 1 working framebuffer. Trying to do a
set_con2fb_map() on a non-allocated vc will freeze the system.
- ensure that succeeding drivers after the first gets mapped to the console
- remove fbcon_preset_display() and modify fbcon_set_display() to include the
former's functionality
- ensure that binding and unbinding succeeds if multiple drivers are mapped to

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.

Minor fix to the Kconfig for RTCs: don't display section headers for I2C or
SPI unless they're configured. And depend on SPI_MASTER; having slave
support wouldn't help.

Tested on the AT32AP7000/ATSTK1000. Driver does only suport time, wake up
and a very simple alarm, because of hardware limitations.
Hardware documentation can be found in the AT32AP7000 data sheet, which can
be downloaded from
http://www.atmel.com/dyn/products/datasheets.asp?family_id=682
From: David Brownell <david-b@pacbell.net>
- Strike some alarm setup code that's no longer needed.
(This patch seems to have gotten lost somewhere...)
- Make the driver name (and its module alias) match what
the platform setup code uses, so the driver can bind
and hotplug.

Convert rtc-rs5c372 to be a "new style" I2C driver, and update the
Kconfig text to be more complete..
Verified on an OMAP H4 development platform, along with a board
init patch to declare its rv5c387a device.
Only one defconfig -- powerpc/linkstation -- uses this driver; but
several other platforms use it, just without defconfig support.
Such platforms need to be converted so (a) their I2C adapter driver
supports new-style drivers, and (b) board init code declares this
I2C device.

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.

This patch fixes access to memory that has not been allocated:
i2o_msg_get_wait() can returns errors different from I2O_QUEUE_EMPTY. But the
result is checked only against this code. If it is not I2O_QUEUE_EMPTY then
we dereference the error code as the pointer later.

This patch fixes a number of issues in i2o_cfg_passthru{,32}:
- i2o_msg_get_wait() return vaile is not checked;
- i2o_message memory leaks on error paths;
- infinite loop to sg_list_cleanup in passthru32
It's important issue because of i2o_cfg_passthru is used by raidutils for
monitorig controllers state, and in case of memory shortage it leads to the
node crash or disk IO stall.

drivers/isdn/capi/capi.c: In function 'handle_minor_send':
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).
