Pull probes fixes from Masami Hiramatsu:

 - objpool: Fix choosing allocation for percpu slots

   Fixes to allocate objpool's percpu slots correctly according to the
   GFP flag. It checks whether "any bit" in GFP_ATOMIC is set to choose
   the vmalloc source, but it should check "all bits" in GFP_ATOMIC flag
   is set, because GFP_ATOMIC is a combined flag.

 - tracing/probes: Fix MAX_TRACE_ARGS limit handling

   If more than MAX_TRACE_ARGS are passed for creating a probe event,
   the entries over MAX_TRACE_ARG in trace_arg array are not
   initialized. Thus if the kernel accesses those entries, it crashes.
   This rejects creating event if the number of arguments is over
   MAX_TRACE_ARGS.

 - tracing: Consider the NUL character when validating the event length

   A strlen() is used when parsing the event name, and the original code
   does not consider the terminal null byte. Thus it can pass the name
   one byte longer than the buffer. This fixes to check it correctly.
