3.2.84-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: David Howells <dhowells@xxxxxxxxxx> commit f7d665627e103e82d34306c7d3f6f46f387c0d8b upstream. x86_64 needs to use compat_sys_keyctl for 32-bit userspace rather than calling sys_keyctl(). The latter will work in a lot of cases, thereby hiding the issue.
