Merge tag 'kgdb-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux
Pull kgdb updates from Daniel Thompson:
"The major change here is the work from Douglas Anderson that reworks
the way kdb stack traces are handled on SMP systems. The effect is to
allow all CPUs to issue their stack trace which reduced the need for
architecture specific code to support stack tracing.
Also included are general of clean ups from Doug and myself:
- Remove some unused variables or arguments.
- Tidy up the kdb escape handling code and fix a couple of odd corner
cases.
- Better ignore escape characters that do not form part of an escape
sequence. This mostly benefits vi users since they are most likely
to press escape as a nervous habit but it won't harm anyone else"
* tag 'kgdb-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux:
kdb: Tweak escape handling for vi users
kdb: Improve handling of characters from different input sources
kdb: Remove special case logic from kdb_read()
kdb: Simplify code to fetch characters from console
kdb: Tidy up code to handle escape sequences
kdb: Avoid array subscript warnings on non-SMP builds
kdb: Fix stack crawling on 'running' CPUs that aren't the master
kdb: Fix "btc <cpu>" crash if the CPU didn't round up
kdb: Remove unused "argcount" param from kdb_bt1(); make btaprompt bool
kgdb: Remove unused DCPU_SSTEP definition
