In some situations, a NUMA guest that supports

For some arch, kexec shall map the reserved pages, then use them, when
we try to start the kdump service.
Now kexec will never unmap the reserved pages, once it fails to continue
starting the kdump service.
Make a pair of reserved pages in kdump starting path, whatever kexec
fails or not.

At the moment the IRQCHIP_DECLARE macro is only declared locally in
'drivers/irqchip/irqchip.h'. That prevents from using it directly in arch/*
directories whenever irqchip drivers only exist there, which happens in a few
cases (e.g. arc, arm, microblaze and mips).
This patch makes the macro to

What I cannot find here is the answer to: why? I am not familiar with
the driver so this is just guessing that you wanted to notify
userspace about connected/disconnected
