From: Zhang Xiantao <[EMAIL PROTECTED]> Date: Sat, 8 Dec 2007 10:42:49 +0800 Subject: [PATCH] kvm: qemu: Sync ID cache after DMA memory access.
Since IA64 has splitted icache and dcache, hardware's dma
operations ensures the synchronization, in virtualziation world
we also need to guarantee it through software.
