812 | This builds a kernel image that is capable of running anywhere | ||
813 | in the RMA (real memory area) at any 16k-aligned base address. | ||
814 | The kernel is linked as a position-independent executable (PIE) | ||
815 | and contains dynamic relocations which are processed early | ||
816 | in the bootup process. | ||
817 | |||
818 | One use is for the kexec on panic case where the recovery kernel | ||
