commitbba496656aupstream. Boot fails with GCC latent entropy plugin enabled. This is due to early boot functions trying to access 'latent_entropy' global data while the kernel is not relocated at its final destination yet. As there is no way to tell GCC to use PTRRELOC() to access it, disable latent entropy plugin in early_32.o and feature-fixups.o and code-patching.o Fixes:38addce8b6("gcc-plugins: Add latent_entropy plugin") Cc: stable@vger.kernel.org # v4.9+ Reported-by: Erhard Furtner <erhard_f@mailbox.org> Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://bugzilla.kernel.org/show_bug.cgi?id=215217 Link: https://lore.kernel.org/r/2bac55483b8daf5b1caa163a45fa5f9cdbe18be4.1640178426.git.christophe.leroy@csgroup.eu Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
