Subject: [Qemu-devel] [PATCH_v2 3/9] target-openrisc: Remove executable flag for every page
Date: Tue, 22 Oct 2013 02:12:39 +0200 [thread overview]
Message-ID: <1382400765-26377-4-git-send-email-sebastian@macke.de> (raw)
In-Reply-To: <1382400765-26377-1-git-send-email-sebastian@macke.de>
Pages should be flagged executable only if the tlb executable flag is
set or the mmu is off.
