Well, i can't compile the last xen-unstable, due to the following error:

multi.c: In function גsh_page_fault__guest_2ג:
multi.c:3114: error: גSHUTDOWN_crashג undeclared (first use in this function)
multi.c:3114: error: (Each undeclared identifier is reported only once
multi.c:3114: error: for each function it appears in.)
make[6]: *** [guest_2.o] Error 1

So, i'm trying to revert back, to see if i can compile it...
