SubjectRe: [PATCH] kernel:gen_kheaders:Replace md5sum to sha256sum

MD5 and SHA256 are secure (or, in the case of MD5, not so secure) hash
algorithms, not encryption mechanisms.

Looking at this script, I'm not convinced that it relies on MD5 being
a cryptophically secure hash function. It appears to me as if this
script uses MD5 to simply detect innocent changes to a set of files as
opposed to guarding against malicious attacks. I also found that
sha256sum takes almost three times longer than md5sum. So, in the
absence of security requirements, md5sum might actually be the better
choice because it's faster.
