The MC68040 MMU provides the size of the access that triggers the page fault. This size is set in the Special Status Word which is written in the stack frame of the access fault exception. So we need the size in m68k_cpu_unassigned_access() and m68k_cpu_handle_mmu_fault(). To be able to do that, this patch modifies the prototype of handle_mmu_fault handler, tlb_fill() and probe_write(). do_unassigned_access() already includes a size parameter. This patch also updates handle_mmu_fault handlers and tlb_fill() of all targets (only parameter, no code change).

We had a check using TARGET_VIRT_ADDR_SPACE_BITS to make sure that the allocation coming in from the command-line option was not too large, but that didn't include target-specific knowledge about other restrictions on user-space. Remove several target-specific hacks in linux-user/main.c. For MIPS and Nios, we can replace them with proper adjustments to the respective target's TARGET_VIRT_ADDR_SPACE_BITS definition. For ARM, we had no existing ifdef but I suspect that the current default value of 0xf7000000 was chosen with this in mind. Define a workable value in linux-user/arm/, and also document why the special case is required.

cpu_nios2_init() always falls back to TYPE_NIOS2_CPU object regardless of cpu_model. Put fallback logic into nios2_cpu_class_by_name() which would translate any cpu_model into TYPE_NIOS2_CPU class and replace cpu_nios2_init() with cpu_generic_init() Signed-off-by: NIgor Mammedov <imammedo@redhat.com> Reviewed-by: NPhilippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <1503592308-93913-14-git-send-email-imammedo@redhat.com> Signed-off-by: NEduardo Habkost <ehabkost@redhat.com>
