This patch removes controller driver infrastructure which supported
the now-removed usb_ep_{alloc,free}_buffer() calls.
As can be seen, many of the implementations of this were broken to
various degrees. Many didn't properly return dma-coherent mappings;
those which did so were necessarily ugly because of bogosity in the
underlying dma_free_coherent() calls ... which on many platforms
can't be called from the same contexts (notably in_irq) from which
their dma_alloc_coherent() sibling can be called.
The main potential downside of removing this is that gadget drivers
wouldn't have specific knowledge that the controller drivers have:
endpoints that aren't dma-capable don't need any dma mappings at all.

Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers.
This patch just removes the interface and its users; later patches will
remove controller driver support.
- This interface is invariably not implemented correctly in the
controller drivers (e.g. using dma pools, a mechanism which
post-dates the interface by several years).
- At this point no gadget driver really *needs* to use it. In
current kernels, any driver that needs such a mechanism could
allocate a dma pool themselves.
Removing this interface is thus a simplification and improvement.

This patch updates some of the documentation about DMA buffer management
for USB, and ways to avoid extra copying. Our understanding of the issues
has improved over time.
- Most drivers should *avoid* the dma-coherent allocators. There are
a few exceptions (like the HID driver).
- Some methods are currently commented out; it seems folk writing
USB drivers aren't doing performance tuning at that level yet.
- Just avoid highmem; there's no good way to pass an "I can do highmem
DMA" capability through a driver stack. This is easy, everything
already avoids highmem. But it'd be nice if x86_32 systems with much
physical memory could use it directly with network adapters and mass

Since I combed a few small bugs away, this also fixes the small races we

USB: usb host side can be configured given PCMCIA
Platforms with PCMCIA support can implement host-side USB with "sl811_cs",
so make sure this menu shows up on platforms with PCMCIA.

USB: usb-storage: use kthread_stop() for the control thread
This patch (as923) makes usb-storage's control thread use
kthread_should_stop()/kthread_stop(). The scanning thread can't be
similarly converted until the core kthread implementation allows
threads to call do_exit().
The advantage of this change is that we can now be certain the control
thread has terminated before storage_disconnect() returns. This will
simplify the locking requirements when autosuspend support is added.
