The library code built under arch/x86/boot/startup is not intended to be linked into vmlinux but only into the decompressor and/or the EFI stub. This means objtool validation is not needed here, and may result in false positive errors for things like missing retpolines. So disable it for all objects added to lib-y Tested-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: H.

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 reStructuredText 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.
