ARM: 8457/1: psci-smp is built only for SMP The PSCI SMP implementation is built only when both CONFIG_SMP and CONFIG_ARM_PSCI are set, so a configuration that has the latter but not the former can get a link error when it tries to call psci_smp_available(). arch/arm/mach-tegra/built-in.o: In function `tegra114_cpuidle_init': cpuidle-tegra114.c:(.init.text+0x52a): undefined reference to `psci_smp_available' This corrects the #ifdef in the psci.h header file to match the Makefile conditional we have for building that function.

ARM: use const and __initconst for smp_operations These smp_operations structures are not over-written, so add "const" qualifier and replace __initdata with __initconst.

ARM: migrate to common PSCI client code Now that the common PSCI client code has been factored out to drivers/firmware, and made safe for 32-bit use, move the 32-bit ARM code over to it. This results in a moderate reduction of duplicated lines, and will prevent further duplication as the PSCI client code is updated for PSCI 1.0 and beyond. The two legacy platform users of the PSCI invocation code are updated to account for interface changes. In both cases the power state parameter (which is constant) is now generated using macros, so that the pack/unpack logic can be killed in preparation for PSCI 1.0 power state changes.

arm: Fix compile warning for psci Commit e71246a23acbc89e9cb4ebf1558d60e65733479f changes psci_init from a function returning a void to an int, but does not change the non CONFIG_ARM_PSCI implementation to return a value, which causes a compile warning. Just return 0.

arm: introduce psci_smp_ops Rename virt_smp_ops to psci_smp_ops and move them to arch/arm/kernel/psci_smp.c. Remove mach-virt/platsmp.c, now unused. Compile psci_smp if CONFIG_ARM_PSCI and CONFIG_SMP. Add a cpu_die smp_op based on psci_ops.cpu_off. Initialize PSCI before setting smp_ops in setup_arch. If PSCI is available on the platform, prefer psci_smp_ops over the platform smp_ops.
