This update contains one bug fix: some lines can come out truncated,
because of the safety cutoff. This happened because I forgot to update
the size when status packets began to be printed.

The rest is:
 - Comments updates
 - Allow snooping with pkmap on x86_64, which is cache-coherent
 - Enlarge event buffers (certainly we can have a couple of pages)
 - Add event counter

First touch upon usbmon for 2.6.18.

This patch (as707) improves the FSBR operation in uhci-hcd by turning it
off more quickly when it isn't needed.  FSBR puts a noticeable load on a
computer's PCI bus, so it should be disabled as soon as possible when it
isn't in use.  The patch leaves it running for only 10 ms after the last
URB stops using it, on the theory that this should be long enough for a
driver to submit another URB if it wants keep FSBR going.

This patch (as706) removes the private hc_inaccessible flag from
uhci-hcd.  It's not needed because it conveys exactly the same
information as the generic HCD_FLAG_HW_ACCESSIBLE bit.

In its place goes a new flag recording whether the controller is dead.
The new code allows a complete device reset to resurrect a dead
controller (although usbcore doesn't yet implement such a facility).

This patch (as705) contains a small set of updates for uhci-hcd written
mostly by Dave Brownell:

  * Root hub suspend messages come out labeled as root hub messages;
    PCI messages should only come out when the pci device suspends.

  * Rename the reset() method to better match its init() role

  * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub
    suspend/resume errors.

  * When an URB fails, associate the message with the usb device not
    the host controller (it still hides endpoint and direction)

This fixes coverity Bug #390.

With the following code

	ret = ep->branch = balance(isp116x, ep->period, ep->load);
	if (ret < 0)
		goto fail;

the problem is that ret and balance are of the type int, and ep->branch is u16.
so the int balance() returns gets reduced to u16 and then converted to an int again,
which removes the sign. Maybe the following little c program can explain it better:

<viro> huh?
<viro> add_disk() sets the damn flag

<viro> but usually you know if you'd done add_disk() on that puppy anyway

In ub, nobody upstream should ever see half-constructed disks before

the list on the path of no return. With that fix in place, we do
not need to test GENHD_FL_UP.

This updates the EHCI driver by adding an improved scheduler for the
transaction translators, found in USB 2.0 hubs and used for low and
full speed devices.

 - adds periodic_tt_usecs() and some helper functions, which does
   the same thing that "periodic_usecs" does, except on the other
   side of the TT, i.e.  it calculates the low/fullspeed bandwidth
   usage instead of highspeed.

 - adds a tt_available() function which is the new implementation
   of what tt_no_collision() does ... while tt_no_collision() ensures
   that each TT handles only 1 periodic transfer at a time (a very
   pessimistic approach) this version instead tracks bandwidth and
   allows each TT to handle as many transfers as will fit on each TT's
   downstream bus (closer to best-case).

The new scheduler is selected by a config option, marked as EXPERIMENTAL
so it can be tested (and more broadly reviewed) for a while until it
seems safe to remove the original scheduler.
