Is it actually safe to circumvent tlb_remove_page()? It does rather more than just free_page()! That's why I used a ForeignPage hook when writing the i386 code. It's certainly *not* safe to assume that whoever wrote that part of the x86/64 port understood all the ramifications of what they were doing. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
