This fixes remaining sparse warnings in vringh and mic by using virtio 1.0 compliant wrappers. This also needs by get_user patches to avoid getting warnings from these calls. Tested by running vringh_test. Rusty, I prefer fixing all these warnings for 3.19, any objections? Michael S.

Hi, This patchset allows vhost to be used with legacy virtio when guest and host have a different endianness. It is compatible with modern virtio and can be fully compiled out through kernel config. FWIW, I could flawlessly kexec/reboot guests from ppc64 to ppc64le and back. I could also migrate from a ppc64 to a ppc64le host and back. No regressions on x86 as expected. My experimental QEMU tree
