7a27d904bd Minor style nit:
Use the interface number from the USB interface descriptor
like in the other USB serial drivers. These numbers are not
supposed to be different, though in theory they can. Make sure
that the driver then uses the interface number given by the USB
descriptor, and not the logical index of the USB stack.

For the future:
Whenever the term "index" is used in the USB code, it refers to
a number computed by the USB stack.
Whenever the term "number" is used in the USB code, it refers to
a number in a USB descriptor.

b5ba3bdb25 Support multiple interface devices. The driver had previously hardcoded
support for only the first port, but the CP2105 can have multiple ports.
Although this allowed the first port to mostly work on multi port devices,
there could be issues with this arrangement.

Update the man page to reflect support for both ports and the CP2105.

Many thanks to Silicon Labs (www.silabs.com) for providing a CP2105-EK

2db99100a4 Improve the handling of static DMA buffers that use non-default memory
attributes (currently just BUS_DMA_NOCACHE):
- Don't call pmap_change_attr() on the returned address, instead use
  kmem_alloc_contig() to ask the VM system for memory with the requested
  attribute.
- As a result, always use kmem_alloc_contig() for non-default memory
  attributes, even for sub-page allocations.  This requires adjusting
  bus_dmamem_free()'s logic for determining which free routine to use.
- For x86, add a new dummy bus_dmamap that is used for static DMA
  buffers allocated via kmem_alloc_contig().  bus_dmamem_free() can then
  use the map pointer to determine which free routine to use.
- For powerpc, add a new flag to the allocated map (bus_dmamem_alloc()
  always creates a real map on powerpc) to indicate which free routine
  should be used.

Note that the BUS_DMA_NOCACHE handling in powerpc is currently #ifdef'd out.
I have left it disabled but updated it to match x86.

a6e829596d Fix an issue that crept in with the previous descriptor tidyup.
When forming aggregates, the last descriptor was now not being
correctly setup - instead, the "setuplasttxdesc" call was being
handed the first descriptor in the last subframe, rather than the
last descriptor in the last subframe.

This showed up as "bad series0 hwrate" messages, as the final
descriptor just didn't have any of the rate control information
squirreled away.

ea53792942 Fix races between in_lltable_prefix_free(), lla_lookup(),
llentry_free() and arptimer():

o Use callout_init_rw() for lle timeout, this allows us safely
  disestablish them.
  - This allows us to simplify the arptimer() and make it
    race safe.
o Consistently use ifp->if_afdata_lock to lock access to
  linked lists in the lle hashes.
o Introduce new lle flag LLE_LINKED, which marks an entry that
  is attached to the hash.
  - Use LLE_LINKED to avoid double unlinking via consequent
    calls to llentry_free().
  - Mark lle with LLE_DELETED via |= operation istead of =,
    so that other flags won't be lost.
o Make LLE_ADDREF(), LLE_REMREF() and LLE_FREE_LOCKED() more
  consistent and provide more informative KASSERTs.

The patch is a collaborative work of all submitters and myself.

50e91f8ce1 Just like the other file systems found in /sys/fs, g_vfs_open()
should be paried with g_vfs_close().  Though g_vfs_close() is a wrapper
around g_wither_geom_close(), r206130 added the following test in
g_vfs_open():

	if (bo->bo_private != vp)
		return (EBUSY);

  Which will cause a 'Device busy' error inside reiserfs_mountfs() if
the same file system is re-mounted again after umount or mounting failure:

	(case 1, /dev/ad4s3 is not a valid REISERFS partition)
	# mount -t reiserfs -o ro /dev/ad4s3 /mnt
	mount: /dev/ad4s3: Invalid argument
	# mount -t msdosfs -o ro /dev/ad4s3 /mnt
	mount: /dev/ad4s3: Device busy

	(case 2, /dev/ad4s3 is a valid REISERFS partition)
	# mount -t reiserfs -o ro /dev/ad4s3 /mnt
	# umount /mnt
	# mount -t reiserfs -o ro /dev/ad4s3 /mnt
	mount: /dev/ad4s3: Device busy

  On the other hand, g_vfs_close() 'fixed' the above cases by doing an
extra step to keep 'sc->sc_bo->bo_private' and 'cp->private' pointers
synchronised.

e1a18e46e1 Do a trivial reformatting of the comment, to record the proper commit
message for r238973:

Rdtsc instruction is not synchronized, it seems on some Intel cores it
can bypass even the locked instructions.  As a result, rdtsc executed
on different cores may return unordered TSC values even when the rdtsc
appearance in the instruction sequences is provably ordered.

Similarly to what has been done in r238755 for TSC synchronization
test, add explicit fences right before rdtsc in the timecounters 'get'
functions.  Intel recommends to use LFENCE, while AMD refers to
MFENCE. For VIA follow what Linux does and use LFENCE.  With this
change, I see no reordered reads of TSC on Nehalem.

Change the rmb() to inlined CPUID in the SMP TSC synchronization test.
On i386, locked instruction is used for rmb(), and as noted earlier,
it is not enough. Since i386 machine may not support SSE2, do simplest
possible synchronization with CPUID.
