[Kgdb-bugreport] [PATCH 10/15] powerpc: Replace hardcoded offset by BREAK_INSTR_SIZE

[Jason W. <jas...@wi...>]

From: Michal Simek <mo...@mo...>

kgdb_handle_breakpoint checks the first arch_kgdb_breakpoint
which is not known by gdb that's why is necessary jump over
it. The jump lenght is equal to BREAK_INSTR_SIZE that's
why is cleaner to use defined macro instead of hardcoded
non-described offset.
