IRQ_WORK_FLAGS is defined simply to 3UL. This is confusing as it
says nothing about its purpose. Define IRQ_WORK_FLAGS as a bitwise

While we're at it: use the BIT() macro for all flags.

Sorry, my git send-email config seems incorrect. The patch subject is
not right. So NACK this series, will repost v2.

X86 MP spec defines 3 different interrupt modes:
1) PIC Mode—bypasses all APIC components and forces the system to
operate in single-processor mode.
2) Virtual Wire Mode—uses an APIC as a virtual wire, but otherwise
operates the same as PIC Mode.
3) Symmetric I/O Mode—enables the sy

lapic_shutdown() invocation is moved after disable_IO_APIC(). In fact
in disable_IO_APIC(), it not only calls clear_IO_APIC() to disable
IO-APIC, also sets LAPIC and IO-APIC to make system be PIC or

Kdump kernel will become very slow if 'noapic' is specified in kernel

This is because the legacy irq mode is disabled in crashed kernel before

This macro is only used by net/ipv6/mcast.c, but there is no reason
why it must be BUILD_BUG_ON_NULL().

On kvm guest, the latest kernel will always print warning during kdump kernel
boots
as below. The reaons is the legacy irq mode is disabled before jump to
kexec/kdump
kernel. So the do { xxx } while (queued && max_loops > 0) can't handle if
pending
irq exists in APIC IRR since LAPIC is disabled.
