commit 967ec1f55256eb2d601ce0be5916bb46085f36db
Author: Mark Wielaard <mjw@redhat.com>
Date:   Mon Sep 19 15:42:19 2011 +0200

    Remove arch specific _stp_probing_32bit_app() and _stp_get_regparm().
    
    Both functions were doing more than necessary and didn't actually need
    access to the current regs. _STP_PROBE_STATE_USER_MODE tells us whether
    the current probe triggered in user mode. _stp_is_compat_task() tells
    us whether the current task is a 32-on-64 process.
    
    * runtime/compatdefs.h (_stp_is_compat_task): Defined also when CONFIG_COMPAT
      is undefined (to always return false).
    * runtime/loc2c-runtime.h: u_fetch_register() and u_store_register() are
      only called from user space dwarf context. Only needs _stp_is_compat_task()
      test.
    * runtime/regs.c: Remove arch specific _stp_probing_32bit_app() and
      _stp_get_regparm() functions.
    * tapset/i386/registers.stp (_stp_arg): Check regparm directly.
    * tapset/powerpc/registers.stp (probing_32bit_app): Use _stp_is_compat_task()
      test.
    * tapset/s390/registers.stp (probing_32bit_app): Likewise.
    * tapset/x86_64/registers.stp (_stp_arg): Check regparm directly.
      (probing_32bit_app): Use _stp_is_compat_task() test.
      (regparm): Likewise.
