[GIT PULL] process fixes for v5.4-rc2

[Christian Brauner]

Hi Linus,

/* Summary */
This pull request contains a couple of fixes:

- Fix pidfd selftest compilation (Shuah Kahn)
  Due to a false linking instruction in the Makefile compilation for the
  pidfd selftests would fail on some systems.

- Fix compilation for glibc on RISC-V systems (Seth Forshee)
  In some scenarios linux/uapi/linux/sched.h is included where __ASSEMBLY__
  is defined causing a build failure because struct clone_args was not
  guarded by an #ifndef __ASSEMBLY__.

- Add missing clone3() and struct clone_args kernel-doc (Christian Brauner)
  clone3() and struct clone_args were missing kernel-docs. (The goal is to
  use kernel-doc for any function or type where it's worth it.)
  For struct clone_args this also contains a comment about the fact that
  it's versioned by size.

The following changes since commit 54ecb8f7028c5eb3d740bb82b0f1d90f2df63c5c:
