Subject: [PATCH v2 0/3] RISC-V: Fix cpumask rework fall-out

	Hi all,

This patch series fixes the fall-out from commit 26fb751ca37846c9
("RISC-V: Do not use cpumask data structure for hartid bitmap"), cfr.
the discussion in thread[1].  Most important, it fixes userspace crashes
on systems where the first CPU does not have the lowest Hart ID.

Changes compared to v1[2]:
  - Add Reviewed-by, Tested-by.

Thanks for applying!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
