Specific comments: * powerpc should be cleaned up at the same time to use the common infrastructure. I don't want duplicated code hanging around in arch/powerpc * The code you add to common/ should obey the coding style of other files in that directory * Arguably we should have an asm-generic for the xencomm guest-access macros. That's a Linux-ism which I think fits well in this particular case. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
