1. These are previous changes to tpm_buf, which make stack allocations
much more feasible than previously.
2. Migrate low-hanging fruit to use stack allocations.
Jarkko Sakkinen (4):
tpm: Make TPM buffer allocations more robust
tpm, tpm1-cmd: Use stack for trivial cases
tpm, tpm2-cmd: Use stack for trivial cases
tpm_vpm_proxy: Use stack for TPM_CC_SET_LOCALITY
