kexec: take the segment adding out of locate_mem_hole functions
In locate_mem_hole functions, a memory hole is located and added as kexec_segment. But from the name of locate_mem_hole, it should only take responsibility of searching a available memory hole to contain data of a specified size. So in this patch add a new field 'mem' into kexec_buf, then take that kexec segment adding code out of locate_mem_hole_top_down and locate_mem_hole_bottom_up. This make clear of the functionality of locate_mem_hole just like it declars to do. And by this locate_mem_hole_callback chould be used later if anyone want to locate a memory hole for other use. Meanwhile Vivek suggested opening code function __kexec_add_segment(), that way we have to retreive ksegment pointer once and it is easy to read. So just do it in this patch and remove __kexec_add_segment() since no one use it anymore. Signed-off-by: Baoquan He <bhe@redhat.com> Acked-by: Vivek Goyal <vgoyal@redhat.com> Cc: Eric W.
