This reverts commit 9b5580359a84 ("scripts/gdb: add documentation
example for radix tree")

The python implementation of radix tree was merged at the same time as a
refactoring of the radix tree implementation and doesn't work.  The
feature is being reverted, thus we revert the documentation as well.

Pull SCSI fixes from James Bottomley:
 "Two straightforward fixes.

  One is a concurrency issue only affecting SAS connected SATA drives,
  but which could hang the storage subsystem if it triggers (because the
  outstanding command count on error never goes back to zero) and the
  other is a NO_TAG fallout from the switch to hostwide tags which
  causes the system to crash on module insertion (we've checked
  carefully and only the 53c700 family of drivers is vulnerable to this
  issue)"

Pull USB fixes from Greg KH:
 "Here are a bunch (65) of USB fixes for 4.7-rc4.  Sorry about the
  quantity, I've been slow in getting these out.

  The majority are the "normal" gadget, musb, and xhci fixes, that we
  all are used to.  There are also a few other tiny fixes resolving a
  number of reported issues that showed up in 4.7-rc1.

  All of these have been in linux-next"
