Change seems okay but what did break this? I see only three references 
to workaround_expand_exec_shield_cs_limit:

./os/linux/os_linux.cpp:  workaround_expand_exec_shield_cs_limit();
./os_cpu/linux_x86/os_linux_x86.hpp:  static void 
workaround_expand_exec_shield_cs_limit();
./os_cpu/linux_x86/os_linux_x86.cpp:void 
os::workaround_expand_exec_shield_cs_limit() {

and there are no recent changes to any of those files. ???

Thanks,
David
