In addition only if CONFIG_IMA_KEXEC is configured, is the IMA measurement list carried across kexec. After moving the rest of ima.c to drivers/of/kexec.c, this changes. Notice how drivers/of/Kconfig includes kexec.o: obj-$(CONFIG_KEXEC_FILE) += kexec.o It is not dependent on CONFIG_HAVE_IMA_KEXEC. Shouldn't all of the functions defined in ima.c being moved to kexec.o be defined within a CONFIG_HAVE_IMA_KEXEC ifdef? thanks, Mimi
