[GIT PULL] integrity subsystem updates for v5.11

[Mimi Zohar]

Hi Linus,

Included in this pull request are just 3 patches.  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 3 patches included in this pull request:
- 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.

thanks,

Mimi
