[Qemu-devel] [PULL 13/15] linux-user/sparc: Put address for data faults where linux-user expects it |

From: Peter Maydell <address@hidden>
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.
