They are real 64 bit processes, i.e. the region 0 is not used. Can I abuse this region 0 for mapping the addresses of the neighbor process into this region ? E.g. if process A has got an address at 0x6000000000001000, then I am going to map it for B at address 0x0000000000001000 ? Wont anything break ? (I need this trick because the source address can correspond to anything, like initialized data, BSS, anonymous allocation, etc, i.e. some SHM just wont work.) Any advice will be appreciated.
