Hi, This patch series introduces a new config option CONFIG_KEXEC_FILE for the newly introduce kexec syscall (kexec_file_load()). Now all the code for new syscall compiles only if CONFIG_KEXEC_FILE=y. This new option currently is available only on x86_64. Other arches can enable it as as when support is added. There is some code in new syscall which currently requires -mcmodel=large gcc option and that option is supported only in gcc 4.4 onwards. So old users of gcc complained about it. Now old gcc users should be fine as long as they don't set CONFIG_KEXEC_FILE=y. As a new option is introduced, now CONFIG_KEXEC does not have to select CRYPTO. So I have put in a patch to remove select CRYPTO=y from all the arches.
