Hi,

Please help ot backport commit: d54ce6158e35 ("kgdb: fix to kill breakpoints on initmem after boot") to stable kernels. Below are comments from kgdb/kdb maintainer in this thread [1]:

"BTW this is not Cc:ed to stable and I do wonder if it crosses the threshold to be considered a fix rather than a feature. Normally I consider adding safety rails for kgdb to be a new feature but, in this case, the problem would easily ensnare an inexperienced developer who is doing nothing more than debugging their own driver (assuming they correctly marked their probe function as .init) so I think this weighs in favour of being a fix."

Now queued up to the 5.10 and 5.11 stable trees, thanks.
