Unconditionally reporting a value seen on the P4 or older invokes functionality like io_apic_get_unique_id() on 32-bit builds, resulting in a panic() with sufficiently many CPUs and/or IO-APICs. Doing what that function does would be the hypervisor's responsibility anyway, so makes no sense to be used when running on Xen. Uniformly report a more modern version; this shouldn't matter much as both LAPIC and IO-APIC are being managed entirely / mostly by the hypervisor.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
