Hello!

This series removes Kconfig "select" clauses and #ifdef directives that
are no longer necessary give that SRCU is now unconditionally enabled,
courtesy of new-age printk() requirements. Finally, the SRCU Kconfig
option is removed entirely.

1. arch/x86: Remove "select SRCU".

2. arch/arm64/kvm: Remove "select SRCU".

3. arch/mips/kvm: Remove "select SRCU".

4. arch/powerpc/kvm: Remove "select SRCU".

5. arch/riscv/kvm: Remove "select SRCU".

6. arch/s390/kvm: Remove "select SRCU".

7. block: Remove "select SRCU".

8. drivers/base: Remove CONFIG_SRCU.

9. drivers/clk: Remove "select SRCU".

10. drivers/cpufreq: Remove "select SRCU".

11. drivers/dax: Remove "select SRCU".

12. drivers/devfreq: Remove "select SRCU".

13. drivers/hwtracing/stm: Remove "select SRCU".

14. drivers/md: Remove "select SRCU".

15. drivers/net: Remove "select SRCU".

16. drivers/opp: Remove "select SRCU".

19. fs/dlm: Remove "select SRCU".

20. fs/notify: Remove "select SRCU".

21. fs/quota: Remove "select SRCU".

22. init: Remove "select SRCU".
