  kdb: Tweak escape handling for vi users (2019-10-28 12:08:29 +0000)

----------------------------------------------------------------
kgdb patches for 5.5-rc1

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.
