sh: intc - convert voyagergx code
This patch converts the sh-specific voyagergx interrupt code to make use
of intc. A lot of "interesting" old cruft gets replaced with intc tables
and some simple demux code.
- All interrupt sources in the sm501 data sheet are now in the header.
- The number and order of IRQ values are disconnected from register bits.
- Interrupt sources now start from IRQ 200.
- set_irq_chained_handler() is now used to hook up the demux function.
In the future it would probably make sense to move the interrupt demuxer
into into the mfd driver, but this is probably a nice step in the right
direction until that happens.
Tested on a R2D-1 board using the serial port hooked up to the sm501.

signalfd simplification
This simplifies signalfd code, by avoiding it to remain attached to the
sighand during its lifetime.
In this way, the signalfd remain attached to the sighand only during
poll(2) (and select and epoll) and read(2). This also allows to remove
all the custom "tsk == current" checks in kernel/signal.c, since
dequeue_signal() will only be called by "current".
I think this is also what Ben was suggesting time ago.
The external effect of this, is that a thread can extract only its own
private signals and the group ones. I think this is an acceptable
behaviour, in that those are the signals the thread would be able to
fetch w/out signalfd.

This patch makes pppol2tp_xmit call skb_cow_head so that we don't modify
cloned skb data. It also gets rid of skb2 we only need to preserve the
original skb for congestion notification, which is only applicable for
ppp_async and ppp_sync.
The other semantic change made here is the removal of socket accounting
for data tranmitted out of pppol2tp_xmit. The original code leaked any
existing socket skb accounting. We could fix this by dropping the
original skb owner. However, this is undesirable as the packet has not
physically left the host yet.
In fact, all other tunnels in the kernel do not account skb's passing
through to their own socket. In partciular, ESP over UDP does not do
so and it is the closest tunnel type to PPPoL2TP. So this patch simply
removes the socket accounting in pppol2tp_xmit. The accounting still
applies to control packets of course.
