Linus Torvalds eeee78cf77 Some clean ups and small fixes, but the biggest change is the addition
of the TRACE_DEFINE_ENUM() macro that can be used by tracepoints.
 
 Tracepoints have helper functions for the TP_printk() called
 __print_symbolic() and __print_flags() that lets a numeric number be
 displayed as a a human comprehensible text. What is placed in the
 TP_printk() is also shown in the tracepoint format file such that
 user space tools like perf and trace-cmd can parse the binary data
 and express the values too. Unfortunately, the way the TRACE_EVENT()
 macro works, anything placed in the TP_printk() will be shown pretty
 much exactly as is. The problem arises when enums are used. That's
 because unlike macros, enums will not be changed into their values
 by the C pre-processor. Thus, the enum string is exported to the
 format file, and this makes it useless for user space tools.
 
 The TRACE_DEFINE_ENUM() solves this by converting the enum strings
 in the TP_printk() format into their number, and that is what is
 shown to user space. For example, the tracepoint tlb_flush currently
 has this in its format file:
 
      __print_symbolic(REC->reason,
         { TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" },
         { TLB_REMOTE_SHOOTDOWN, "remote shootdown" },
         { TLB_LOCAL_SHOOTDOWN, "local shootdown" },
         { TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" })
 
 After adding:
 
      TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH);
      TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN);
      TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN);
      TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN);
 
 Its format file will contain this:
 
      __print_symbolic(REC->reason,
         { 0, "flush on task switch" },
         { 1, "remote shootdown" },
         { 2, "local shootdown" },
         { 3, "local mm shootdown" })
