[PATCH 0/2] Preserve TPM log across kexec

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
