Hi,

Here are patches for bootconfig to rejects unexpected config data after null
character and other cleanups including tools/bootconfig to consolidate
bootconfig initialization with errors, and skipping internal tree sanity
check in kernel.

The last one is initially reported by Sang-Heon Jeon [1].
