Subject: [Qemu-devel] [PATCH] cpu: flush TB cache when loading VMState
Date: Wed, 10 Jan 2018 16:48:46 +0300	[thread overview]
Message-ID: <20180110134846.12940.99993.stgit@pasha-VirtualBox> (raw)

Flushing TB cache is required because TBs key in the cache may match
different code which existed in the previous state.
