Without cacheflush,qemu sometimes fail with segment fault on loongson

cpu_restore_state,tcg_gen_code-pc will be called frequently.

From: Huang Ying ying.hu...@intel.com
In QEMU-KVM, physical address != RAM address. While MCE simulation
needs physical address instead of RAM address. So
kvm_physical_memory_addr_from_ram() is implemented to do the
conversion, and it is invoked before being filled in the IA32_MCi_ADDR
MSR.
This will deadlock when the I/O thread is used, since the
CPU thread is blocked waiting for qemu_system_ready.
The synchronization is unnecessary since this is before
cpu_synchronize_all_post_init().
