Subject: [PATCH 5.3 080/148] sched: Add __ASSEMBLY__ guards around struct clone_args

From: Seth Forshee <seth.forshee@...onical.com>

commit 61129dd29f7962f278b618a2a3e8fdb986a66dc8 upstream.

The addition of struct clone_args to uapi/linux/sched.h is not protected
by __ASSEMBLY__ guards, causing a failure to build from source for glibc
on RISC-V. Add the guards to fix this.

Fixes: 7f192e3cd316 ("fork: add clone3")
