From c84e6224f5c9788cf8356cc2aad32b4a12d9834e Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Mon, 17 Mar 2014 14:05:54 +0000 Subject: [PATCH] xen/arm: next_module: Skip module if the size is 0 When the the module size is 0, it means that the module was not provided by the user. It can happen, if the user choose to boot without initrd. In this case, both fields (start and size) are zeroed. Therefore, next_module will return 0 every time if there is other non-zero module after this one. This can happen when the XSM module is added.
