Subject: [GIT PULL] random number generator updates for 6.19-rc1

Hi Linus,

Please pull the following small set of updates to the random number generator:

- Dynamically allocate cpumasks off of the stack, potentially, if the kernel is
  configured for a lot of CPUs, to handle a -Wframe-larger-than case.

- The removal of next_pseudo_random32() after the last user was switched over
  to the prandom interface.

- The removal of get_random_u{8,16,32,64}_wait() functions, as there were no
  users of those at all.

- Some house keeping changes - a few grammar cleanups in the comments,
  system_unbound_wq was renamed to system_dfl_wq, and static_key_initialized no
  longer needs to be checked.

These have been sitting in my tree for a while and haven't surface any issues.

Thanks,
Jason
