Since commit83109d5d5f("x86/build: Warn on orphan section placement"), we get a warning for objects in orphan sections. The cpuidle implementation for OMAP causes this when CONFIG_CPU_IDLE is disabled: arm-linux-gnueabi-ld: warning: orphan section `__cpuidle_method_of_table' from `arch/arm/mach-omap2/pm33xx-core.o' being placed in section `__cpuidle_method_of_table' arm-linux-gnueabi-ld: warning: orphan section `__cpuidle_method_of_table' from `arch/arm/mach-omap2/pm33xx-core.o' being placed in section `__cpuidle_method_of_table' arm-linux-gnueabi-ld: warning: orphan section `__cpuidle_method_of_table' from `arch/arm/mach-omap2/pm33xx-core.o' being placed in section `__cpuidle_method_of_table' Change the definition of CPUIDLE_METHOD_OF_DECLARE() to silently drop the table and all code referenced from it when CONFIG_CPU_IDLE is disabled.

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.
