From 8d8cb956e0a679fcf0a8e24f1b2f34e038cdd48e Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 6 Nov 2017 18:33:25 +0000 Subject: [PATCH] linux-user/sparc: Put address for data faults where linux-user expects it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In the user-mode-only version of sparc_cpu_handle_mmu_fault(), we must save the fault address for a data fault into the CPU state's mmu registers, because the code in linux-user/main.c expects to find it there in order to populate the si_addr field of the guest siginfo.
