find the solution for this one: We don't need to set ident map for boot_param and command line in head_64.S as we already get arch/x86/kernel/head64.c, and could use early_ioremap to access and copy them out. Now, will check if can put purgatory above 4g. Thanks Yinghai _______________________________________________ kexec mailing list [email protected] http://lists.infradead.org/mailman/listinfo/kexec
