Thanks. That's very useful. I recently ran into this problem that
the new log buffer is a pain to dump from qemu gdb.
fwiw there's already some kdump macros in Documentation/kdump
Since you obsoleted them you could remove those (and for log buffer
they do not work anymore)
I don't like the lx-* prefixes.
