kexec_file_load() on powerpc doesn't support kdump kernels yet, so it
returns -ENOTSUPP in that case.
I've recently learned that this errno is internal to the kernel and
isn't supposed to be exposed to userspace. Therefore, change to
-EOPNOTSUPP which is defined in an uapi header.
This does indeed make kexec-tools happier. Before the patch, on
ppc64le:
# ~bauermann/src/kexec-tools/build/sbin/kexec -s -p /boot/vmlinuz
kexec_file_load failed: Unknown error 524
After the patch:
# ~bauermann/src/kexec-tools/build/sbin/kexec -s -p /boot/vmlinuz
kexec_file_load failed: Operation not supported
