The core is nevertheless confined to the ACPI build and refuses to initialize when ACPI is disabled. Move the implementation to drivers/platform/profile and introduce the firmware-independent PLATFORM_PROFILE symbol. Update all provider selectors. Keep provider-specific ACPI dependencies and the platform_profile module name. Isolate access to the legacy ACPI kobject in an optional compatibility object linked into the same module. Retain the legacy ABI on active ACPI systems, and initialize the class even when ACPI is absent or disabled. Use subsys_initcall_sync so the class is ready before built-in thermal and CPUFreq providers, but after ACPI has initialized its compatibility kobject.
