It seems like a lot of complexity for little benefit. AFAICS your final purgatory_64.c is only 36 lines, and all it does is a single (open coded) memcpy(). It seems like we could write that in not many more lines of assembler and avoid all this code. What am I missing? cheers _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
