Subject: [GIT PULL] random number generator fixes for 6.1-rc3

Hi Linus,

This pull contains one fix from Jean-Philippe Brucker, addressing a regression
in which early boot code on ARM64 would use the non-_early variant of the
arch_get_random family of functions, resulting in the architectural random
number generator appearing unavailable during that early phase of boot. The
fix simply changes arch_get_random*() to arch_get_random*_early().

This distinction between these two functions is a bit of an old wart I'm not a
fan of, and for 6.2 I'll see if I can make obsolete the _early variant, so
that one function does the right thing in all contexts without overhead.

Regards,
Jason
