Subject: [Qemu-devel] [PATCH 1.1 1/6] target-xtensa: flush TLB page for new MMU mapping
Date: Sun, 27 May 2012 18:34:49 +0400 [thread overview]
Message-ID: <1338129294-16742-2-git-send-email-jcmvbkbc@gmail.com> (raw)
In-Reply-To: <1338129294-16742-1-git-send-email-jcmvbkbc@gmail.com>
Both old and new mappings need flushing because their VPN may be
different in MMU case.
