linux-next: build warnings from Linus' tree

[Stephen Rothwell]

Hi all,

With just Linus' tree, today's linux-next build (ppc64le perf) produced
these warnings:

util/parse-events.y:1.1-12: warning: deprecated directive, use '%define 
api.pure' [-Wdeprecated]
    1 | %pure-parser
      | ^~~~~~~~~~~~
util/parse-events.y: warning: fix-its can be applied.  Rerun with option 
'--update'. [-Wother]
util/expr.y:13.1-12: warning: deprecated directive, use '%define api.pure' 
[-Wdeprecated]
   13 | %pure-parser
      | ^~~~~~~~~~~~
util/expr.y: warning: fix-its can be applied.  Rerun with option '--update'. 
[-Wother]

I assume this is because I have upgraded bison to version 3.4.1 (from
3.3.2).
