Subject: [GIT PULL] kernel_clone() for v5.10

Hi Linus,

/* Summary */
Here is the kernel_clone() series for v5.10. During the v5.9 merge window we
reworked the process creation codepaths across multiple architectures. After
this work we were only left with the _do_fork() helper based on the struct
kernel_clone_args calling convention. As was pointed out _do_fork() isn't valid
kernelese especially for a helper that isn't just static.

This series removes the _do_fork() helper and introduces the new kernel_clone()
helper. The process creation cleanup didn't change the name to something more
reasonable mainly because _do_fork() was used in quite a few places. So sending
this as a separate series seemed the better strategy.

I originally intended to send this early in the v5.9 development cycle after
the merge window had closed but given that this was touching quite a few places
I decided to defer this until the v5.10 merge window.

The following changes since commit 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5:

  Linux 5.9-rc1 (2020-08-16 13:04:57 -0700)

  sched: remove _do_fork() (2020-08-20 13:12:59 +0200)

/* Testing */
All patches are based on v5.9-rc1 and have been sitting in linux-next since
then. No build failures or warnings were observed. All old and new tests are
passing.

/* Conflicts */
At the time of creating this PR no merge conflicts were reported from linux-next and no merge
conflicts showed up doing a test-merge with current mainline b5fc7a89e58b
("Merge tag 'overflow-v5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux").

Please consider pulling these changes from the signed kernel-clone-v5.9 tag.

Thanks!
Christian
