[PATCH] kexec: allocate buffer in top-down, if specified, correctly

2017-04-26 Thread AKASHI Takahiro
The current kexec_locate_mem_hole(kbuf.top_down == 1) stops searching at the first memory region that has enough space for requested size even if some of higher regions may also have. This behavior is not consistent with locate_hole(hole_end == -1) function of kexec-tools. This patch fixes the bug
