[ Upstream commit 4df0221f9ded8c39aecfb1a80cef346026671cb7 ]
Syscall handlers should not be invoked internally by their symbol names, as these symbols defined by the architecture-defined SYSCALL_DEFINE macro. Fortunately, in the case of ppc64_personality, its call to sys_personality can be replaced with an invocation to the equivalent ksys_personality inline helper in <linux/syscalls.h>.
