      Revert "sysfs: handle duplicate removal attempts in sysfs_remove_group()" · 81440e73
      Greg Kroah-Hartman authored 
      This reverts commit 54d71145.

The root cause of these "inverted" sysfs removals have now been found,
so there is no need for this patch.  Keep this functionality around so
that this type of error doesn't show up in driver code again.

      Staging: tidspbridge: disable driver · 930ba4a3
      Greg Kroah-Hartman authored 
      There seems to be no active maintainer for the driver, and there is an
unfixed security bug, so disable the driver for now.

Hopefully someone steps up to be the maintainer, and works to get this
out of staging, otherwise it will be deleted soon.

      HID: uhid: fix leak for 64/32 UHID_CREATE · 80897aa7
      David Herrmann authored 
      UHID allows short writes so user-space can omit unused fields. We
automatically set them to 0 in the kernel. However, the 64/32 bit
compat-handler didn't do that in the UHID_CREATE fallback. This will
reveal random kernel heap data (of random size, even) to user-space.

Fixes: befde022 ('HID: uhid: make creating devices work on 64/32 systems')

Pull tracing fixes from Steven Rostedt:
 "This includes two fixes.

  1) is a bug fix that happens when root does the following:

     echo function_graph > current_tracer
     modprobe foo
     echo nop > current_tracer

   This causes the ftrace internal accounting to get screwed up and
   crashes ftrace, preventing the user from using the function tracer
   after that.

  2) if a TRACE_EVENT has a string field, and NULL is given for it.

   The internal trace event code does a strlen() and strcpy() on the
   source of field.  If it is NULL it causes the system to oops.

   This bug has been there since 2.6.31, but no TRACE_EVENT ever passed
   in a NULL to the string field, until now"

      We are missing building windfarm_max6690_sensor.o when building
CONFIG_WINDFARM_RM31. Usually all the windfarm drivers are built
and thus this isn't a problem but some more "tailored" setups
(Gentoo ?) building only that driver are not working because
the require sensor module is missing.

      ftrace: Fix function graph with loading of modules · 8a56d776
      Steven Rostedt (Red Hat) authored 
      Commit 8c4f3c3f "ftrace: Check module functions being traced on reload"
fixed module loading and unloading with respect to function tracing, but
it missed the function graph tracer. If you perform the following

 # cd /sys/kernel/debug/tracing
 # echo function_graph > current_tracer
 # modprobe nfsd
 # echo nop > current_tracer

You'll get the following oops message:

The above mentioned commit didn't go far enough. Well, it covered the
function tracer by adding checks in __register_ftrace_function(). The
problem is that the function graph tracer circumvents that (for a slight
efficiency gain when function graph trace is running with a function
tracer. The gain was not worth this).

The problem came with ftrace_startup() which should always be called after
__register_ftrace_function(), if you want this bug to be completely fixed.

Anyway, this solution moves __register_ftrace_function() inside of
ftrace_startup() and removes the need to call them both.

New tracepoints have been added that have allowed for NULL pointers
being assigned to strings. To fix this, change the TRACE_EVENT() code
to check for NULL and if it is, it will assign "(null)" to it instead
(similar to what glibc printf does).
