1) don't let other threads trying to bang on aux channel interrupt the
defer timeout/logic
2) don't let other threads interrupt the i2c over aux logic

Technically, according to people who actually have the DP spec, this
should not be required.  In practice, it makes some troublesome Dell
monitor (and perhaps others) work, so probably a case of "It's compliant
if it works with windows" on the hw vendor's part..

v2: rebased to come before DPCD/AUX logging patch for easier backport
to stable branches.

  the pmem driver.

  The compilation problems from the initial posting have been fixed,
  this has appeared in a -next release with no reported issues, and it
  picked up an ack from Ingo.  There is no pressing need to merge this
  in 4.6- rc2.  However, if we wait until 4.7 the new memcpy_mcsafe()
  capability will ship without a user in 4.6-final"

  x86, pmem: use memcpy_mcsafe() for memcpy_from_pmem()

The seccomp filter support requires careful handling of task registers.  This
includes reloading of the return value (%r28) and proper syscall exit if
secure_computing() returned -1.

Additionally we need to sign-extend the syscall number from signed 32bit to
signed 64bit in do_syscall_trace_enter() since the ptrace interface only allows
storing 32bit values in compat mode.
