Merge tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull more random number generator updates from Jason Donenfeld:
 "Two remaining changes that are now possible after you merged a few
  other trees:

   - #include <asm/archrandom.h> can be removed from random.h now,
     making the direct use of the arch_random_* API more of a private
     implementation detail between the archs and random.c, rather than
     something for general consumers.

   - Two additional uses of prandom_u32_max() snuck in during the
     initial phase of pulls, so these have been converted to
     get_random_u32_below(), and now the deprecated prandom_u32_max()
     alias -- which was just a wrapper around get_random_u32_below() --
     can be removed.

  In addition, there is one fix:

   - Check efi_rt_services_supported() before attempting to use an EFI
     runtime function.

     This affected EFI systems that disable runtime services yet still
     boot via EFI (e.g. the reporter's Lenovo Thinkpad X13s laptop), as
     well systems where EFI runtime services have been forcibly
     disabled, such as on PREEMPT_RT.

     On those machines, a very early and hard to diagnose crash would
     happen, preventing boot"
