[ Upstream commit 9de7695925d5d2d2085681ba935857246eb2817d ]
When both of X86_LOCAL_APIC and X86_THERMAL_VECTOR are disabled,
the irq tracing produces a W=1 build warning for the tracing
definitions:
In file included from include/trace/trace_events.h:27,
from include/trace/define_trace.h:113,
from arch/x86/include/asm/trace/irq_vectors.h:383,
from arch/x86/kernel/irq.c:29:
include/trace/stages/init.h:2:23: error: 'str__irq_vectors__trace_system_name' defined but not used [-Werror=unused-const-variable=]
Make the tracepoints conditional on the same symbosl that guard
their usage.

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.
