[BUG] No PS/2 mouse in 2.6.16 - bisect result

[Bodo Eggert <7eggert@gmx.de>]

As decribed in the thread
http://groups.google.com/groups?selm=5V6m7-81J-11@gated-at.bofh.it ,
my mouse does not work in 2.6.16.

Copying the drivers/input/mouse directory from 2.6.15 helped, but 
bisecting gave the below result. Reverting this patch did help,
so it must be some kind of conflict with an input patch, but I can't find 
a way to make git tell me all commits between foo and bar affecting baz.
I don't intend to do it manually.

    Add early-boot-safety check to cond_resched()

    Just to be safe, we should not trigger a conditional reschedule during
    the early boot sequence.  We've historically done some questionable
    early on, and the safety warnings in __might_sleep() are generally
    turned off during that period, so there might be problems lurking.

    This affects CONFIG_PREEMPT_VOLUNTARY, which takes over might_sleep() 
to
    cause a voluntary conditional reschedule.
