Date: Fri, 26 Sep 2008 13:05:16 -0500 From: Jason Wessel <jason.wessel@...driver.com> To: torvalds@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, kgdb-bugreport@...ts.sourceforge.net Subject: [PATCH 1/5] kgdb: could not write to the last of valid memory with kgdb From: Atsuo Igarashi <atsuo_igarashi@...peaks.co.jp> On the ARM architecture, kgdb will crash the kernel if the last byte of valid memory is written due to a flush_icache_range flushing beyond the memory boundary.
