Add ftdi product ID for Lenz LI-USB, a model train interface.  This
was NOT tested against 2.6.35, but a similar patch was tested with the
CentOS 2.6.18-194.11.1.el5 kernel.  It wasn't clear to me what
ordering is being used in ftdi_sio.c, so I inserted the ID after another
model train entry(SPROG_II).

This patch fixes a isoc transfer bug reported by Sander Eikelenboom.
When ep->skip is set, endpoint ring dequeue pointer should be updated
when processed every missed td. Although ring dequeue pointer will also
be updated when ep->skip is clear, leave it intact during missed tds
processing may cause two issues:

1). If the very next valid transfer following missed tds is a short
transfer, its actual_length will be miscalculated;
2). If there are too many missed tds during transfer, new inserted tds
may found the transfer ring full and urb enqueue fails.

The code to increment the TRB pointer has a slight ambiguity that could
lead to a bug on different compilers.  The ANSI C specification does not
specify the precedence of the assignment operator over the postfix
operator.  gcc 4.4 produced the correct code (increment the pointer and
assign the value), but a MIPS compiler that one of John's clients used
assigned the old (unincremented) value.

Remove the unnecessary assignment to make all compilers produce the
correct assembly.

The reset state of twl4030-usb is not sleeping, it starts
up awaken and we need to disable it if we have booted
with a disconnected cable to avoid over consumption on
the default state.

To avoid problems later, we read the current state of the
transceiver from the PHY_PWR_CTRL register. The bootloader
can, anyways, put the device to sleep before us.

I can confirm that the navman driver works with the right device IDs on
my i-gotU GT-600, which has the same device IDs.  Attached is a patch
adding the IDs.

The ISP1760 has some timing requirements where it has to delay a short
period after a write to a register has started.  However, this delay is
from the time the write hits the USB chip (the ISP1760), not from the
time where the processor started processing the write.  So on a quick
enough processor, it is sometimes possible for the write to not hit the
device before we start delaying, and we then violate the part's timing
requirements, so things stop working.

To avoid all this, insert a write barrier after the register write and
before the timing delay/register read so we can guarantee we only start
counting time after the write has hit the device.

* 'radix-tree' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/xfsdev:
  radix-tree: radix_tree_range_tag_if_tagged() can set incorrect tags
  radix-tree: clear all tags in radix_tree_node_rcu_free

Commit ebf8aa44 ("radix-tree:
omplement function radix_tree_range_tag_if_tagged") does not safely
set tags on on intermediate tree nodes. The code walks down the tree
setting tags before it has fully resolved the path to the leaf under
the assumption there will be a leaf slot with the tag set in the
range it is searching.

Unfortunately, this is not a valid assumption - we can abort after
setting a tag on an intermediate node if we overrun the number of
tags we are allowed to set in a batch, or stop scanning because we
we have passed the last scan index before we reach a leaf slot with
the tag we are searching for set.

As a result, we can leave the function with tags set on intemediate
nodes which can be tripped over later by tag-based lookups. The
result of these stale tags is that lookup may end prematurely or
livelock because the lookup cannot make progress.

The fix for the problem involves reocrding the traversal path we
take to the leaf nodes, and only propagating the tags back up the
tree once the tag is set in the leaf node slot. We are already
recording the path for efficient traversal, so there is no
additional overhead to do the intermediately node tag setting in
this manner.

This fixes a radix tree lookup livelock triggered by the new
writeback sync livelock avoidance code introduced in commit
f446daae ("mm: implement writeback
livelock avoidance using page tagging").

Commit f446daae ("mm: implement
writeback livelock avoidance using page tagging") introduced a new
radix tree tag, increasing the number of tags in each node from 2 to
3. It did not, however, fix up the code in
radix_tree_node_rcu_free() that cleans up after radix_tree_shrink()
and hence could leave stray tags set in the new tag array.

The result is that the livelock avoidance code added in the the
above commit would hit stale tags when doing tag based lookups,
resulting in livelocks when trying to traverse the tree.

Fix this problem in radix_tree_node_rcu_free() so it doesn't happen
again in the future by using a loop to walk all the tags up to
RADIX_TREE_MAX_TAGS to clear the stray tags radix_tree_shrink()
leaves behind.
