Yeah, We could probably use the same symbol names for the trampoline and the swapper page-table on 32 and 64 bit and merge the code that handles it between the architectures. Shouldn't be too difficult. We cook something up :-) But do you mind to take this patch first? It fixes the occurence of an erratum on AMD hardware, it is a quite simple fix compared to the rework suggested. In fact, I would like to have a simple patch to fix the problem first (and backport it as necessary) and then go the way to rework the current code differences between 32 and 64 bit.
