Thiago Jung Bauermann bf8a1abc3d powerpc/kexec_file: Fix error code when trying to load kdump kernel ... 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 Fixes: a0458284f0 ("powerpc: Add support code for kexec_file_load()") Cc: stable@vger.kernel.org # v4.10+ Reported-by: Dave Young <dyoung@redhat.com> Signed-off-by: Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com> Reviewed-by: Simon Horman <horms@verge.net.au> Reviewed-by: Dave Young <dyoung@redhat.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>		2018-04-01 00:47:44 +11:00
