There are platforms that simply refuse to correctly function with a 1:1 physical/virtual mapping. But that's not the point here - this patch simply hardcodes saving dmesg to an EFI variable rather than using kmsg_dump and pstore in order to avoid handling the locking, and does nothing whatsoever to change the amount of EFI code involved. -- Matthew Garrett | mjg59@srcf.ucam.org _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
