Yes, if the host linux use 4K page size, we should define TARGET_PAGE_BITS to 12 when compiling qemu. > Also, as long as I have you... can we use getpagesize() instead of > 65536/4096 in qemu_vmalloc()? We tried it at early stage, seems it can't work, because current code very depens on TARGET_PAGE_BITS.
