Subject: [PATCH 2/3] defs.h: fix breakage of compatibility of struct
machdep_table for extension modules
Commit <2f967fb5ebd7> ("crash_taget: fetch_registers support") added new
member get_cpu_reg in the middle of struct machdep_table, which breaks
compatibility of struct machdep_table for extension modules. As the result,
crash gcore command results in unexpected behavior, furthermore may cause
segmentation fault.
Fixes: 2f967fb5ebd7 ("crash_taget: fetch_registers support")
