Seems DavidH has concern and rasied it after you posted v9. Is that
solved?

It looks like this series is ready to go, but it's not clear who should
pick it up. Eric -- would you be the best person? Otherwise, I'm happy to

On kexec file load, the Integrity Measurement Architecture (IMA)

measure it. The command line parameters passed to the kernel in the

The memory area of the TPM measurement log is currently not properly

The of-tree subsystem does not currently preserve the IBM vTPM 1.2 and

device tree (fdt) to carry the TPM measurement log's buffer across kexec.

RISC-V recently added kexec_file() support, which uses enables kexec
IMA. We're the first 32-bit platform to support this, so we found a
build bug.

Simplify tpm_read_log_of() by moving reusable parts of the code into
an inline function that makes it commonly available so it can be
used also for kexec support. Call the new of_tpm_get_sml_parameters()
function from the TPM Open Firmware driver.

Presently ima_get_kexec_buffer() doesn't check if the previous kernel's
ima-kexec-buffer lies outside the addressable memory range. This can result
in a kernel panic if the new kernel is booted with 'mem=X' arg and the
ima-kexec-buffer was allocated beyond that range by the pre
