virt/kvm/irqchip.c is including "irq.h" from the arch-specific KVM source directory (i.e. not from arch/*/include) for the sole purpose of retrieving irqchip_in_kernel. Making the function inline in a header that is already included, such as asm/kvm_host.h, is not possible because it needs to look at struct kvm which is defined after asm/kvm_host.h is included. So add a kvm_arch_irqchip_in_kernel non-inline function; irqchip_in_kernel() is only performance critical on arm64 and x86, and the non-inline function is enough on all other architectures. irq.h can then be deleted from all architectures except x86.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
