  kdb: Remove the misfeature 'KDBFLAGS' (2020-06-02 15:15:46 +0100)

----------------------------------------------------------------
kgdb patches for 5.8-rc1

By far the biggest change in this cycle are the changes that allow much
earlier debug of systems that are hooked up via UART by taking advantage
of the earlycon framework to implement the kgdb I/O hooks before handing
over to the regular polling I/O drivers once they are available. When
discussing Doug's work we also found and fixed an broken
raw_smp_processor_id() sequence in in_dbg_master().

Also included are a collection of much smaller fixes and tweaks: a
couple of tweaks to ged rid of doc gen or coccicheck warnings, future
proof some internal calculations that made implicit power-of-2
assumptions and eliminate some rather weird handling of magic
environment variables in kdb.
