Since the only user of this function is in arch/x86/kernel/acpi, you can either create a header file there or re-use sleep.h. If you want to leave it here, do you want to protect it with CONFIG_X86_ACPI_MADT_WAKEUP? -- Sathyanarayanan Kuppuswamy Linux Kernel Developer _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
