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
the console

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.

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.

Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.
In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(
Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)
Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.
Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.
