From 3b279f73fa37bec8d3ba04a15f5153d6491cffaf Mon Sep 17 00:00:00 2001 From: Anton Johansson Date: Wed, 12 Jun 2024 15:30:31 +0200 Subject: [PATCH] accel/tcg: Fix typo causing tb->page_addr[1] to not be recorded MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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.
