Merge tag 'kgdb-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux

Pull kgdb updates from Daniel Thompson:
 "A relatively modest collection of changes:

   - Adopt kstrtoint() and kstrtol() instead of the simple_strtoXX
     family for better error checking of user input.

   - Align the print behavour when breakpoints are enabled and disabled
     by adopting the current behaviour of breakpoint disable for both.

   - Remove some of the (rather odd and user hostile) hex fallbacks and
     require kdb users to prefix with 0x instead.

   - Tidy up (and fix) control code handling in kdb's keyboard code.
     This makes the control code handling at the keyboard behave the
     same way as it does via the UART.

   - Switch my own entry in MAINTAINERS to my @kernel.org address"
