  serial: kgdboc: Fix NMI-safety problems from keyboard reset code (2024-04-26 17:14:10 +0100)

----------------------------------------------------------------
kgdb patches for 6.10

Nine patches this cycle and they split into just three topics:

1. Adopt coccinelle's recommendation to adopt str_plural().
2. A set of seven patches to refactor kdb_read() to improve both code clarity
   and it's discipline with respect to fixed size buffers. This isn't just a
   refactor. Between them these also fix a cursor movement redraw problem and
   two buffer overflows (one latent and one real, albeit difficult to
   tickle).
3. Fix an NMI-safety problem when enqueuing kdb's keyboard reset code.

I wrote eight of the nine patches in this collection so many thanks to Doug
Anderson for the reviews. The changes that affects drivers/tty/serial is
acked by Greg KH.
