[PATCH v2 0/2] kgdb: x86: fix breakpoint removal problems

[Florian Rommel]

This series fixes two problems with KGDB on x86 concerning the removal
of breakpoints, causing the kernel to hang.  Note that breakpoint
removal is not only performed when explicitly deleting a breakpoint,
but also happens before continuing execution or single stepping.

v2:
 - Add missing stub implementation for kgdb_after_mark_readonly in [1/2]
   when KGDB disabled
 - Link to v1: https://lore.kernel.org/all/20240811232208.234261-1-mail@xxxxxxxxxxxx/

  x86/kgdb: convert early breakpoints to poke breakpoints
  x86/kgdb: fix hang on failed breakpoint removal
