Various fixes for tracing:

 - Suppress the errors that is_signed_type() causes static analysis tools

 - Fix a return value of traceprobe_parse_event_name()

 - Fix NULL pointer dereference from failed ftrace enabling

 - Fix NULL pointer dereference by asking for registers from eprobes

 - Make eprobes consistent with kprobes/uprobes, filters and histograms

      tracing: Suppress sparse warnings triggered by is_signed_type()

Lukas Bulwahn (1):
      tracing: React to error return from traceprobe_parse_event_name()

Steven Rostedt (Google) (7):
      tracing/perf: Fix double put of trace event when init fails
      tracing/eprobes: Do not allow eprobes to use $stack, or % for regs
      tracing/eprobes: Do not hardcode $comm as a string
      tracing/eprobes: Fix reading of string fields
      tracing/eprobes: Have event probes be consistent with kprobes and uprobes
      tracing/probes: Have kprobes and uprobes use $COMM too
      tracing: Have filter accept "common_cpu" to be consistent
