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". 17. drivers/pci/controller: Remove "select SRCU". 18. fs/btrfs: 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". 23. kernel/power: Remove "select SRCU". 24. mm: Remove "select SRCU". 25. fs: Remove CONFIG_SRCU. 26. kernel/notifier: Remove CONFIG_SRCU. 27. rcu: Remove CONFIG_SRCU.
