David Howells 3cde0e742e x86/syscalls/64: Add compat_sys_keyctl for 32-bit userspace 
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.
