Re: [Xen-merge] [patch] SMP alternatives for i386

Overall technically, I like this patch. Philosophically, I agree with it as well - but might I strongly suggest that you avoid the .section .previous directives and use the nestable .pushsection, .popsection instead? We are almost to the complexity point with fault handling and alternatives that we will need nested section overrides.

Fortunaly we don't need that at the moment. And in case we'll really need it some day it will not be *that* easy. The pointers in the fixup section will point to the wrong location because we run the UP code not in-place but copy it to another address ...

cheers,

Gerd
