This commit adds a kernel feature to have the kernel support
for Intel Memory Protection Extensions (MPX).
A quote from kernel arch/x86/Kconfig:
"MPX provides hardware features that can be used in conjuction
with compiler-instrumented code to check memory references. It
is designed to detect buffer overflow or underflow bugs."
Intel MPX is available, e.g., on Skylake and on Goldmont (e.g.,
Intel 570x).
Looks good to me.
Which branches (kernel versions) are the target for this ? 4.8/4.9/4.10 ?
