So you're suggesting commit messages should use variable names and
prefixes from the code instead of being hum

So the two end up being the "compressed kernel" and "kernel proper".

Make it not confusing.
ZO: arch/x86/boot/compressed/vmlinux
VO: vmlinux
setup + ZO ==> bzImage.
compressed kernel is just compress

We already do move the compressed kernel close to the end of the buffer.
However, there's still overlapping beween kernel proper's .brk/.b
Boris found data from boot stage can not be used kernel stage.
Bootloader allocate buffer according to init_size in hdr, and load the
ZO (arch/x86/boot/compressed/vmlinux) from start of that buffer.
During running of ZO, ZO move itself to the middle of buffer at
z_extract_offset to make sure that
