Subject[GIT PULL] kgdb changes for v4.20-rc3
Hi Linus

Normally pull requests for kgdb come from Jason Wessel but he's seems to
have been struggling for time this dev cycle so I've stepped in. That
I've put this together at (somewhat past) the last minute goes some way

The following changes since commit ccda4af0f4b92f7b4c308d3acc262f4a7e3affad:

Linux 4.20-rc2 (2018-11-11 17:12:31 -0600)

are available in the Git repository at: tags/kgdb-fixes-4.20-rc3

kdb: kdb_support: mark expected switch fall-throughs (2018-11-13 20:38:50 +0000)

kgdb fixes for 4.20-rc3

The most important changes here are two fixes for kdb regressions causes by
the hashing of %p pointers together with a fix for a potential overflow in
kdb tab completion handling (and warning fix).

Also included are a set of changes in preparation to (eventually) enable
