[ Upstream commit 70bad345e622c23bb530016925c936ab04a646ac ] When the kernel is comiled with CONFIG_IRQ_REMAP=y but without CONFIG_IOMMU_INTEL compilation fails since commit def054b01a8678 with an undefined reference to device_rbtree_find(). This patch makes sure that intel specific code is only compiled with CONFIG_IOMMU_INTEL=y.

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.
