Comment 11 for bug 1398274

Sorry, I have to add more commits for TPM 2.0 trusted keys.
In v4.5 kernel:
6674ff1 tpm_ibmvtpm: properly handle interrupted packet receptions
b8ba1e7 tpm_tis: Tighten IRQ auto-probing
e3837e7 tpm_tis: Refactor the interrupt setup
7ab4032 tpm_tis: Get rid of the duplicate IRQ probing code
2511204 tpm: rework tpm_get_timeouts()
036bb38 tpm_tis: Ensure interrupts are disabled when the driver starts
727f28b tpm_tis: Use devm_free_irq not free_irq
f728643 tpm_tis: further simplify calculation of ordinal duration

There are also some bug fixes patches queued in maintainer's tree for v4.6. Once 4.6-rc1 is released, we will give the commits.
If 16.04 couldn't wait for 4.6-rc1, 16.04 should pick this fixes at least which will be in 4.5.1 stable. https://git.kernel.org/cgit/linux/kernel/git/jmorris/linux-security.git/commit/?h=next&id=c0b5eed110dcf520aadafefbcc40658cbdd18b95
