On the Xen developer summit we agreed to start with a minimal approach
first. Based on looking at the last ~50 XSA patches, I do think we can
do *without* the in-place patching and would propose to tackle this
approach later or not at all.
Indeed. The prototype V1 that I posted last Friday works at a function
level. I guess the only reason to make anything more complicated would
be to patch the asm code in entry.S.
