#     initramfs: do not show compression mode choice if INITRAMFS_SOURCE is empty
#     
#     Since commit ddd09bcc899f ("initramfs: make compression options not
#     depend on INITRAMFS_SOURCE"), Kconfig asks the compression mode for
#     the built-in initramfs regardless of INITRAMFS_SOURCE.
#     
#     It is technically simpler, but pointless from a UI perspective,
#     Linus says [1].
#     
#     When INITRAMFS_SOURCE is empty, usr/Makefile creates a tiny default
#     cpio, which is so small that nobody cares about the compression.
#     
#     This commit hides the Kconfig choice in that case. The default cpio
#     is embedded without compression, which was the original behavior.

The function free_memmap() references

This is often because free_memmap lacks a __meminit 
annotation or the annotation of memblock_free is wrong.
