[Qemu-devel] sparc mmu bug(and fix) seen with NetBSD

When using QEMU 0.9.1 for sparc emulation on i386 booting NetBSD 4.0 
miniroot.fs a bug with the MMU is seen. A fault type is mis-aligned with
the fault status register. This is seen by NetBSD with a copy on write
that causes a write fault, with no fault type in the register, NetBSD just
returns to the faulting instruction, causing an infinite loop.
Below is a patch to the 0.9.1 source, however I see the same problem
in the subversion source.
