commit 94cbf48e332d87d85592cf774a45b5fa8e9ae027
Author: Mark Wielaard <mjw@redhat.com>
Date:   Wed Jun 23 21:47:53 2010 +0200

    Correct testing for compat task. Always use our own test.
    
    is_compat_task(), when defined in the kernel, is really just for testing
    whether or not we are in a 32-compat syscall. It does not definitely tell
    us whether or not the current task is a 32bit compat task. So always use
    our own test_thread_flag() with the arch specific TIF_flag.
    
    * runtime/autoconf-is-compat-task.c: Removed.
    * buildrun.cxx (compile_pass): Remove is-compat-task check.
    * runtime/compatdefs.h: Detect s390 specific TIF flag. Always define
      _stp_is_compat_task() when CONFIG_COMPAT defined.
    * tapset/conversions.stp (user_long): Use _stp_is_compat_task().
      (user_long_warn): Likewise.
