Pull integrity subsystem updates from Mimi Zohar:
"Just three patches here. Other integrity changes are being upstreamed
via EFI (defines a common EFI secure and trusted boot IMA policy) and
BPF LSM (exporting the IMA file cache hash info based on inode).
The three patches included here:
- bug fix: fail calculating the file hash, when a file not opened for
read and the attempt to re-open it for read fails.
- defer processing the "ima_appraise" boot command line option to
avoid enabling different modes (e.g. fix, log) to when the secure
boot flag is available on arm.
- defines "ima-buf" as the default IMA buffer measurement template in
preparation for the builtin integrity "critical data" policy"
