KVS: Kernel Version Switcher

# Credits
|
||||
kxtzownsu - Writing KVS & Providing kernver 0 & 1 files
|
||||
crossystem - Providing kerner 2 files
|
||||
?? - Providing kernver 3 files (very sorry, but I couldn't find their username)
|
||||
katie - Getting me a working POC (told me to use `tpmc` instead of `tpm_manager_client`)
|
||||
Google - y'know.. writing `tpmc` and giving me the idea for this (due to a glitch, my one chromebook got set to kernver 0)
|
||||
# kvs
|
||||
KVS: Kernel Version Switcher, made to easily switch the tpm_kernver for Chromebooks.
