[PATCH 1/N, MPX, x86_64] Intel MPX support in glibc for x86_64

Authentication-results: sourceware.org; auth=none

Hi All!

Attached patch is the first of the set of patches that add support for Intel MPX technology (see e.g. http://software.intel.com/sites/default/files/319433-015.pdf, Chapter 9) in Glibc for x86_64. Namely, this particular patch introduces bounds storing/restoring in _dl_runtime_resolve.

Is it ok to install?


Thanks,
Igor
