Hi
An issue was fixed with the TPM space buffer size. The buffer is used to
store in-TPM objects while swapped out of the TPM for a /dev/tpmrm0
session. The code incorrectly used PAGE_SIZE, which obviously can vary.
With v5.9 changes the buffer has a fixed size of 16 kB.
In addition, the PR contains support for acquiring TPM even log from
TPM2 ACPI table. This method is used by QEMU in particular.
