Some Logitech mice have a tilt wheel which register as HWHEEL buttons.
The events are positive for a click to the right and negative for a
click to the left. Applications expect the opposite, though.
I suspect this affects a lot more Logitech mice, but these are the only
two I have. I tested this using evtest and a GTK application. A similar
Microsoft Intellimouse I have works correctly.

This is alternative implementation of sg content iterator introduced
by commit 83e7d317... from Pierre Ossman in next-20080716. As there's
already an sg iterator which iterates over sg entries themselves, name
this sg_mapping_iterator.
Slightly edited description from the original implementation follows.
Iteration over a sg list is not that trivial when you take into
account that memory pages might have to be mapped before being used.
Unfortunately, that means that some parts of the kernel restrict
themselves to directly accesible memory just to not have to deal with
the mess.
This patch adds a simple iterator system that allows any code to
easily traverse an sg list and not have to deal with all the details.
The user can decide to consume part of the iteration. Also, iteration
can be stopped and resumed later if releasing the kmap between
iteration steps is necessary. These features are useful to implement
piecemeal sg copying for interrupt drive PIO for example.

Add a couple of tests to make sure the host driver handles highmem

This patch completely reworks the RX path in order to be
more accurate about what is going on with the MAC.
We no longer read the error from the MLSR register instead read
the descriptor status register which reflects, the error per descriptor.
We now allocate skbs on the fly in r6040_rx, and we handle allocation
failure instead of simply dropping the packet. Remove the
rx_free_desc counter of r6040_private structure since we
allocate skbs in the RX path.
r6040_rx_buf_alloc is now removed and becomes unuseless.

Using multiple cores in the same package to handle received traffic
does not appear to provide a performance benefit. Therefore use CPU
