svn commit: r311521 - head/sys/kern

New Revision: 311521

Log:
  Explicitely add "opt_compat.h" to kern_exec.c: fix powerpc LINT builds.
  
  sys/ptrace.h includes sys/signal.h, which includes sys/_sigset.h.
  Note that sys/_sigset.h only defines osigset_t if COMPAT_43 was defined.
  
  Two lines later, sys/ptrace.h includes machine/reg.h, which in case of
  powerpc, includes opt_compat.h.
  
  After the include headers reordering in r311345, we have sys/ptrace.h
  included before sys/sysproto.h.
  
  If COMPAT_43 was requested in the kernel config, the result is that
  sys/_sigset.h does not define osigset_t, but sys/sysproto.h sees
  COMPAT_43 and uses osigset_t.
  
  Fix this by explicitely including opt_compat.h to cover the whole
  kern/kern_exec.c scope.
