Subject: [PATCH] dma: Let dma_memory_rw_relaxed() take MemTxAttrs argument
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
We will add the MemTxAttrs argument to dma_memory_rw() in
the next commit. Since dma_memory_rw_relaxed() is only used
by dma_memory_rw(), modify it first in a separate commit to
keep the next commit easier to review.
CVE: CVE-2021-3611
Upstream-Status: Backport [https://git.qemu.org/?p=qemu.git;a=commit;h=4afd0f2f220ec3dc8518b8de0d66cbf8d2fd1be7]
