[RFC 06/16] arm64: alternative: Mark .altinstr_replacement as containing executable instructions

From: Raphael Gault
Date: Thu May 16 2019 - 06:40:59 EST


Until now, the section .altinstr_replacement wasn't marked as containing
executable instructions on arm64. This patch changes that so that it is
coherent with what is done on x86.
