From eea11aedcfe18b29d6e63243bc1acb51441ef523 Mon Sep 17 00:00:00 2001 From: Giacomo Travaglini Date: Mon, 6 Nov 2017 15:22:43 +0000 Subject: [PATCH] arch-arm: Removing Serializing flag from ISB ISB Serializing behaviour is guaranteed by IsSquashAfter, which is inherently serializing; when instruction is commited, consecutive instructions are flushed and refetched.
