Date: Thu, 5 Aug 2010 09:37:51 -0500 From: Jason Wessel <jason.wessel@...driver.com> To: torvalds@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, kgdb-bugreport@...ts.sourceforge.net, Michal Simek <monstr@...str.eu>, Jason Wessel <jason.wessel@...driver.com> 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.
