as there's no config CONSOLE (never has been as far as I can tell) and
noone has ever missed that piece of code, it should be safe to remove
it making the kernel a tiny bit less complex.

ARM ELF files use symbols with special names $a, $t, $d to identify regions of
ARM code, Thumb code and data within code sections. This can cause confusing
output from the perf tools, especially for partially stripped binaries, or
binaries containing user-added zero-sized symbols (which may occur in
hand-written assembler which hasn't been fully annotated with .size
directives).
This patch filters out these symbols at load time.

This change addresses the following situation:
- Thread A acquires the rwsem for read
- Thread B tries to acquire the rwsem for write, notices there is already
an active owner for the rwsem.
- Thread C tries to acquire the rwsem for read, notices that thread B already
tried to acquire it.
- Thread C grabs the spinlock and queues itself on the wait queue.
- Thread B grabs the spinlock and queues itself behind C. At this point A is
the only remaining active owner on the rwsem.
In this situation thread B could notice that it was the last active writer
on the rwsem, and decide to wake C to let it proceed in parallel with A
since they both only want the rwsem for read.

Previously each waiting thread added a bias of RWSEM_WAITING_BIAS. With
this change, the bias is added only once to indicate that the wait list is
non-empty.
This has a few nice properties which will be used in following changes:
- when the spinlock is held and the waiter list is known to be non-empty,
count < RWSEM_WAITING_BIAS <=> there is an active writer on that sem
- count == RWSEM_WAITING_BIAS <=> there are waiting threads and no
active readers/writers on that sem

In __rwsem_do_wake(), we can skip the active count check unless we come
there from up_xxxx(). Also when checking the active count, it is not
actually necessary to increment it; this allows us to get rid of the read
side undo code and simplify the calculation of the final rwsem count
adjustment once we've counted the reader threads to wake.
The basic observation is the following. When there are waiter threads on
a rwsem and the spinlock is held, other threads can only increment the
active count by trying to grab the rwsem in down_xxxx(). However
down_xxxx() will notice there are waiter threads and take the down_failed
path, blocking to acquire the spinlock on the way there. Therefore, a
thread observing an active count of zero with waiters queued and the
spinlock held, is protected against other threads acquiring the rwsem
until it wakes the last waiter or releases the spinlock.

This is in preparation for later changes in the series.
In __rwsem_do_wake(), the first queued waiter is checked first in order to
determine whether it's a writer or a reader. The code paths diverge at
this point. The code that checks and increments the rwsem active count is
duplicated on both sides - the point is that later changes in the series
will be able to independently modify both sides.

Sysfs interface:
* Fan/pwm control is the same as for F71889FG
* Temperature and voltage sensor handling is largely the same as for
the F71889FG
- Has one temperature sensor less (doesn't have temp3)
- Misses one voltage sensor (doesn't have V6, thus in6_input refers to
what in7_input refers for F71889FG)
For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up
such that it can largely be reused.
