[GIT PULL] integrity: subsystem fixes for v7.1

[Mimi Zohar]

Hi Linus,

There are 2 main changes, 1 feature removal, some code cleanup, and            
a number of bug fixes.

Main changes:
- Detecting secure boot mode was limited to IMA.  Make detecting secure boot
mode accessible to EVM and other LSMs.
- IMA sigv3 support was limited to fsverity.  Add IMA sigv3 support for IMA
regular file hashes and EVM portable signatures.

Remove:
- Remove IMA support for asychronous hash calculation originally added for
hardware acceleration.

Cleanup:
- Remove unnecessary Kconfig CONFIG_MODULE_SIG and CONFIG_KEXEC_SIG tests.
- Add descriptions of the IMA atomic flags.

Bug fixes:
- Like IMA, properly limit EVM "fix" mode.
- Define and call evm_fix_hmac() to update security.evm.
- Fallback to using i_version to detect file change for filesystems that do not
support STATX_CHANGE_COOKIE.
- Address missing kernel support for configured (new) TPM hash algorithms.
- Add missing crypto_shash_final() return value.

Thanks,

Mimi
