Hi; this patch has some changes which seem to be just code motion
(moving the PT_INTERP handling higher up in the function), some
changes which are coding style fixes (braces), some which are
no-behaviour-change changes (using eppnt->foo instead of phdr[i].foo)
and also the actual BTI related functional change. Could you
split them out, please? I think it would make this easier to review.

thanks
