This series resolves an issue on PowerVM and KVM on Power where the memory
the TPM log was held in may become inaccessible or corrupted after a kexec
soft reboot. The solution on these two platforms is to store the whole log
in the device tree because the device tree is preserved across a kexec with
either of the two kexec syscalls.
Regards,
Stefan
