Merge tag 'kgdb-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux

Pull kgdb updates from Daniel Thompson:
 "Just two patches for you this time!

   - During a panic, flush the console before entering kgdb.

     This makes things a little easier to comprehend, especially if an
     NMI backtrace was triggered on all CPUs just before we enter the
     panic routines

   - Correcting a couple of misleading (a.k.a. plain wrong) comments"
