Subject: [PATCH 10/17] kgdb,powerpc: Replace hardcoded offset by BREAK_INSTR_SIZE
From: Michal Simek <monstr@...str.eu>
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.
