On my 32-bit machine, with BREAK_INSTR_SIZE=4 the kgdb_break[] structure allocates 16000 bytes of static kernel memory, which is - by default - to be able to handle up to 1000 concurrent kgdb breakpoints. I might be wrong, but I doubt that in real life someone really needs that many breakpoints, so I suggest to reduce the number of possible kgdb breakpoints and thus reduce the memory footprint of kgdb_break[].
