mpx: Extend siginfo structure to include bound violation information
This patch adds new fields about bound violation into siginfo
structure. si_lower and si_upper are respectively lower bound
and upper bound when bound violation is caused.
This patch updates x86 struct siginfo to enable GDB with MPX support.
[BZ #18696]
* sysdeps/unix/sysv/linux/x86/bits/siginfo.h (_sigfault): Add
si_addr_bnd.
(si_lower): New.
(si_upper): Likewise.
