ima: add Kconfig default measurement list template
This patch adds a Kconfig option to select the default IMA measurement list template. The 'ima' template limited the filedata hash to 20 bytes and the pathname to 255 charaters. The 'ima-ng' measurement list template permits larger hash digests and longer pathnames. Changelog: - keep 'select CRYPTO_HASH_INFO' in 'config IMA' section (Kconfig) (Roberto Sassu); - removed trailing whitespaces (Roberto Sassu). - Lindent fixes Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: Roberto Sassu <roberto.sassu@polito.it>
