Hi all, Here is v2 with the comments from v1 addressed. I also added a patch to the series to add KEXEC_FILE_NO_CMA as a legal flag. I noticed that this was missing when I went to add my KEXEC_FILE_FORCE_DTB flag. Thanks, Brian Changes in v2: - Added a patch to add KEXEC_FILE_NO_CMA as a legal flag - Added a KEXEC_FILE_FORCE_DTB flag to enable carrying over the current boot's DTB on x86. - Modified the commit message to include more reasoning for the change. - Changed a pr_info print to a pr_debug print.

Thanks for that, Andrew! Dave and Baoquan, have you two had a chance to peek at the updated patch set yet? Thanks, Brian

Hi, The #ifdef CONFIG_* which can be replaced by #if defined(), but I do not have a strong opinion. other than that do you have kexec-tools patch ready? It would be better to provide a link so that people can try and test it. Thanks Dave
