Applied patch "exit: panic before exit_mm() on global init exit"

[Christian Brauner]

I've added the patch:

  exit: panic before exit_mm() on global init exit

to
  https://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux.git/log/?h=fixes

I've rewritten the commit message and fixed a typo in the comment.

If noone objects this will be part of the threads-fixes pr early next week.

Thanks!
Christian
