From 4b1a3e1e34ad971b58783d4a24448ccbf5bd8fd4 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 29 Jun 2018 17:17:31 +0100 Subject: accel/tcg: Don't treat invalid TLB entries as needing recheck In get_page_addr_code() when we check whether the TLB entry is marked as TLB_RECHECK, we should not go down that code path if the TLB entry is not valid at all (ie the TLB_INVALID bit is set).
