From 32b089808f125470b3563bf4209c2301fa35c58e Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Sun, 18 Mar 2012 18:31:13 +0200 Subject: memory: check for watchpoints when getting code ram_addr The code to get the ram_addr from a (tlb entry, vaddr) pair checks that the resulting memory is not MMIO, but neglects to check whether the region is hidden by a watchpoint page. Add the missing check.
