This patch is badly mangled , probably by your email client. Be sure to
use 'git send-email' to send your patches, as this generates proper
emails. See the manual:

Why would we store the Linux kernel version on the target? If we were to
do so, why would we not do that for all other packages as well?

Besides, the kernel version is already included in the kernel binary
itself, if you set CONFIG_LOCALVERSION_AUTO=y in your kernel config
file.

If what you need is accountability, then 'make show-info' will dump a
json blurb with a lot of metadata about all packages in your build,
including the kernel version.

Finally, if you need traceability, you probbly already have your kernel
version string in your Buildroot configuration file.

I'll mark this patch as rejected. If you still think there is a valid
use-case for it, that is not covered by one of the above, then please
respin and provide a commit log that explains that use-case.

Regards,
Yann E. MORIN.
