MIPS registers an unassigned access handler which raises a guest bus error exception. However this causes QEMU to crash when KVM is enabled as it isn't called from the main execution loop so longjmp() gets called without a corresponding setjmp(). Until the KVM API can be updated to trigger a guest exception in response to an MMIO exit, prevent the bus error exception being raised from mips_cpu_unassigned_access() if KVM is enabled. The check is at run time since the do_unassigned_access callback is initialised before it is known whether KVM will be enabled. The problem can be triggered with Malta emulation by making the guest write to the reset region at physical address 0x1bf00000, since it is marked read-only which is treated as unassigned for writes.
