  kdb: Fix pager search for multi-line strings (2020-10-01 14:44:08 +0100)

----------------------------------------------------------------
kgdb patches for 5.10-rc1

A fairly modest set of changes for this cycle. Of particular
note are an earlycon fix from Doug Anderson and my own changes to get
kgdb/kdb to honour the kprobe blocklist. The later creates a safety
rail that strongly encourages developers not to place breakpoints in,
for example, arch specific trap handling code.

Also included are a couple of small fixes and tweaks: an API update,
eliminate a coverity dead code warning, improved handling of search
during multi-line printk and a couple of typo corrections.
