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.

FYI: This was the previous attempt that didn't work with the older kexec
syscall: https://lore.kernel.org/lkml/4afde78d-e138-9eee-50e0-dbd32f4dcfe0@linux.ibm.com/T/#m158630d214837e41858b03d4b025e6f96cb8f251 (local)

Doesn't everyone else still need that? Is powerpc the only ones that 
care about the old kexec syscall?
