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.
