Jiabo Feng 提交于 2024-12-12 17:01 . QEMU update to version 8.2.0-26:
From 378d79fa6b9410af702776ffa93865219f273380 Mon Sep 17 00:00:00 2001

Subject: [PATCH] accel/tcg: Fix typo causing tb->page_addr[1] to not be
recorded
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For TBs crossing page boundaries, the 2nd page will never be
recorded/removed, as the index of the 2nd page is computed from the
address of the 1st page. This is due to a typo, fix it.
