Christian Eggers c3d944a367 ARM: 9444/1: add KEEP() keyword to ARM_VECTORS
Without this, the vectors are removed if LD_DEAD_CODE_DATA_ELIMINATION
is enabled.  At startup, the CPU (silently) hangs in the undefined
instruction exception as soon as the first timer interrupt arrives.

On my setup, the system also boots fine without the 2nd and 3rd KEEP()
statements, so I cannot tell whether these are actually required.

[nathan: Use OVERLAY_KEEP() to avoid breaking old ld.lld versions]

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.
