[PATCH v2 0/2] x86/kexec: fix memory leak of elf header buffer

[Baoquan He]

The memory leak is reported by kmemleak detector, has been existing
for very long time. It casue much memory loss on large machine
with huge memory hotplug which will trigger kdump kernel reloading
many times, with kexec_file_load interface.

And in patch 2, clean up is done to remove unneeded
arch_kexec_kernel_image_load() and rename functions.

v1->v2:
 No code change. The v1 post has been acked by Dave Young but not
merged. In v2, just merging the old patch 1 and 2 as per Dave's concern
in v1 post.
