This v2 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. drivers/base: Remove CONFIG_SRCU. 3. drivers/cpufreq: Remove "select SRCU". 4. drivers/dax: Remove "select SRCU". 5. drivers/hwtracing/stm: Remove "select SRCU". 6. drivers/md: Remove "select SRCU". 7. drivers/net: Remove "select SRCU". 8. drivers/pci/controller: Remove "select SRCU". 9. fs: Remove CONFIG_SRCU. 10. fs/btrfs: Remove "select SRCU". 11. fs/dlm: Remove "select SRCU". 12. fs/notify: Remove "select SRCU". 13. fs/quota: Remove "select SRCU". 14. init: Remove "select SRCU". 15. kernel/notifier: Remove CONFIG_SRCU. 16. kernel/power: Remove "select SRCU". 17. kvm: Remove "select SRCU". 18. mm: Remove "select SRCU". 19. tomoyo: Remove "select SRCU". 20. Remove CONFIG_SRCU. Changes since v1: o Added ack and review tags. o Dropped patches taken by their maintainers. o Combined the KVM-related commits into a single commit, as requested by Sean Christopherson. Acks received thus far are qualified by the corresponding architecture. o Added the tomoyo patch based on feedback from Nick Desaulniers.
