[PATCH 1/1] x86/apic: add apic_irqs bitmap to identify irqs from apic

During irq migration, fixup_irqs() in arch/x86/kernel/irq.c will call irq_force_complete_move() for every valid irqs, including whose irq_chip is not apic(like ioapic_chip, msi_chip, etc) kind. While the function irq_force_complete_move() in arch/x86/kernel/apic/io_apic.c will treat all input irqs

[RFC PATCH 1/1] x86/apic: add apic_irqs bitmap to identify irqs from apic

The function irq_force_complete_move() might handle irqs based on the non-apic irq_chip the way apic does, which has the structure irq_cfg as its chip_data. Wrong operations on non-apic irq_chip might make its chip_data changed and bring unexpected issues. Add apic_irqs bitmap to identify irqs from
