Added mct_u232_ioctl (implements TIOCMIWAIT command),
mct_u232_get_icount (implements TIOCGICOUNT command) and
mct_u232_msr_to_icount functions. MCT U232 P9 is one of a few usb to
serail adapters which converts USB +/-5v voltage levels to COM +/-15
voltages. So it can also power COM interfaced devices. This makes it
very usable for legacy COM interfaced data-acquisition hardware. I
tested new implementation with AWARE Electronics RM-60 radiation meter,
which sends pulse via RNG COM line whenever new particle is registered.

The unaligned tests are called after their aligned

Add a set of new tests similar to the existing ones but using
transfer buffers at an "odd" address [ie offset of +1 from
the buffer obtained by kmalloc() or usb_alloc_coherent()]

The new tests are:
#17 : bulk out (like #1) using kmalloc and DMA mapping by USB core.
#18 : bulk in (like #2) using kmalloc and DMA mapping by USB core.
#19 : bulk out (like #1) using usb_alloc_coherent()
#20 : bulk in (like #2) using usb_alloc_coherent()
#21 : control write (like #14)

After changing the p2m mapping to a tree by

  commit 58e05027
    xen: convert p2m to a 3 level tree

and trying to boot a DomU with 615MB of memory, the following crash was
observed in the dump:

kernel direct mapping tables up to 26f00000 @ 1ec4000-1fff000
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<c0107397>] xen_set_pte+0x27/0x60
*pdpt = 0000000000000000 *pde = 0000000000000000

Adding further debug statements showed that when trying to set up
pfn=0x26700 the returned mapping was invalid.

pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003)
pfn=0x26700 calling set_pte(0xc1fe7800, 0x3)

Although the last_pfn obtained from the startup info is 0x26700, which
should in turn not be hit, the additional 8MB which are added as extra
memory normally seem to be ok. This lead to looking into the initial
p2m tree construction, which uses the smaller value and assuming that
there is other code handling the extra memory.

When the p2m tree is set up, the leaves are directly pointed to the
array which the domain builder set up. But if the mapping is not on a
boundary that fits into one p2m page, this will result in the last leaf
being only partially valid. And as the invalid entries are not
initialized in that case, things go badly wrong.

I am trying to fix that by checking whether the current leaf is a
complete map and if not, allocate a completely new page and copy only
the valid pointers there. This may not be the most efficient or elegant
solution, but at least it seems to allow me booting DomUs with memory
assignments all over the range.
