Just as Liping has pointed out, since there is size caculated in mcinfo_common, 
it should be ok for this changes, especially considering just increase the 
size, not decrease. 
Anyway, let's wait for  Frank and Gavin's changes. 

BTW, do you know any usage for this MCA mechanism except Sun? We are 
considering more changes to Xen's MCA and some suggestion is send to mailing 
list (http://lists.xensource.com/archives/html/xen-devel/2008-12/msg00643.html 
gives three options  ), we want get feedback from them and you, to avoid 
suprise in last minutes again.

Thanks
