Hi!

This patch adds necessary changes for proper work of dl_runtime routines both for 32 and 64 bits in MPX mode.

Is it ok for trunk?


Thanks,
Igor

	* sysdeps/i386/dl-trampoline.S (_dl_runtime_profile): Save
	and restore Intel MPX return bound registers
	* sysdeps/x86_64/dl-trampoline.h: Add PRESERVE_BND_REGS_PREFIX to
	call, jump and ret instructions to not loose bounds.
	* sysdeps/x86/bits/link.h (La_i86_retval): Add lrv_bnd0 and
	lrv_bnd1.
