    ACPI, x86: expose some IO-APIC routines when CONFIG_ACPI=n · 2a4ab640
    Feng Tang authored
    Some IO-APIC routines are ACPI specific now, but need to
    be exposed when CONFIG_ACPI=n for the benefit of SFI.
    Remove #ifdef ACPI around these routines:
    io_apic_get_unique_id(int ioapic, int apic_id);
    io_apic_get_version(int ioapic);
    io_apic_get_redir_entries(int ioapic);
    Move these routines from ACPI-specific boot.c to io_apic.c:
    uniq_ioapic_id(u8 id)
    Also, since uniq_ioapic_id() is now no longer static,
    re-name it to io_apic_unique_id() for consistency
    with the other public io_apic routines.
    For simplicity, do not #ifdef the resulting code ACPI || SFI,
    thought that could be done in the future if it is important
    to optimize the !ACPI !SFI IO-APIC x86 kernel for size.
