If you, or anyone else, feels it should not be added to the stable tree,
please let [off-list ref] know about it.

Hi Greg,

This patch caused a regression on mn10300, so please also backport the one
below to fix that. I have verified again that no other architectures had
the same problem beside mn10300.

Subject: [PATCH] mn10300: Select CONFIG_HAVE_UID16 to fix build failure

mn10300 builds fail with

fs/stat.c: In function 'cp_old_stat':
fs/stat.c:163:2: error: 'old_uid_t' undeclared

ipc/util.c: In function 'ipc64_perm_to_ipc_perm':
ipc/util.c:540:2: error: 'old_uid_t' undeclared

Select CONFIG_HAVE_UID16 and remove local definition of CONFIG_UID16
to fix the problem.
