If firmware does not implement AUX_LOOP comand in 32 bit mode it
is unlikely to implement it in 64 bit mode. Same goes for active
multiplexing. See:

Some Wistron based laptops need us to explicitly enable the 'Dritek

Originally, this was just confined to older laptops, but a few Acer
laptops have turned up in 2007 that also need this again.

This is necessary for the freezer to stop sending signals to kernel threads,
which is implemented in the next patch.

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

On some boxes that don't have PS/2 mice connected at startup BIOS
completely disables AUX port and attempts to access it result in
hosed keyboard. Historically we do not trust ACPI/PNP data on
i386 and try to poke AUX port even if we did not find an active
PNP node for it. However in cases when BIOS writers got KBD port
properly described we can assume that they did the right thing
for AUX port as well.

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.
