Jarkko Sakkinen dc828b79fe tpm: Unify the mismatching TPM space buffer sizes
[ Upstream commit 6c4e79d99e ]

The size of the buffers for storing context's and sessions can vary from
arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the
maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be
enough for most use with three handles (that is how many we allow at the
moment). Parametrize the buffer size while doing this, so that it is easier
to revisit this later on if required.
