Cover letter [PATCH 0/4] integrity

This patchset addresses a couple of concerns raised on the mailing list:

- Christoph Hellwig's questioned what is protecting the TPM internal kernel interface from the driver being removed, when it is not builtin. The TPM device should be builtin in order to start collecting measurements at the earliest possible time. When the TPM is not builtin, the internal TPM kernel interface now protects itself from the driver being removed by incrementing the module reference count.

The integrity-TPM-internal-kernel-interface.patch prereqs:
TPM-update-char-dev-BKL-pushdown.patch TPM-num_opens-to-is_open-variable-change.patch TPM-rcu-locking.patch TPM-addition-of-pnp-remove.patch TPM-Fixed-tpm_release-timing.patch

- Discussion on the mailing list questioned the use of special magic values in userspace, concluding these values are already exported to userspace via statfs and their correct/incorrect usage is left up to the userspace application.

- Concern was raised on the lkml mailing list, about adding i_integrity to the inode structure. This patch adds a comment clarifying that i_integrity is only included in the inode if INTEGRITY is configured.
