Date: Tue, 29 Jul 2014 18:48:43 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Max Filippov <jcmvbkbc@...il.com> Subject: [PATCH 3.15 07/37] xtensa: fix sysmem reservation at the end of existing block 3.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Max Filippov <jcmvbkbc@...il.com> commit be6ae382dc153da51cf066c8dd523aa955f02531 upstream. When sysmem reservation occurs exactly at the end of an existing block that block is deleted, because it is incorrectly included in the range of memblocks to remove. Fix that by skipping such block.
