[GIT PULL] misc fixes for v5.11-rc5

[Christian Brauner]

Hi Linus,

Here are some fixes for v5.11-rc5 that should hopefully be fairly
uncontroversial. I've had them sitting around for a bit but only got around
sending them now after concluding the idmapped mounts stuff. Sorry for the
delay.

/* Summary */
- Jann reported sparse complaints because of a missing __user annotation in a
  helper we added way back when we added pidfd_send_signal() to avoid compat
  syscall handling. This contains a fix for this.
- Yanfei replaces a reference in a comment to the _do_fork() helper I removed a
  while ago with a reference to the new kernel_clone() replacement.
- Alexander Guril added a simple coding style fix.

The following changes since commit 7c53f6b671f4aba70ff15e1b05148b10d58c2837:

  Linux 5.11-rc3 (2021-01-10 14:34:50 -0800)
