mainlining shenanigans
501a78cbc1
The recent LPM changes to setup_rfi_flush() are causing some section
mismatch warnings because we removed the __init annotation on
setup_rfi_flush():
The function setup_rfi_flush() references
the function __init ppc64_bolted_size().
the function __init memblock_alloc_base().
The references are actually in init_fallback_flush(), but that is
inlined into setup_rfi_flush().
These references are safe because:
- only pseries calls setup_rfi_flush() at runtime
- pseries always passes L1D_FLUSH_FALLBACK at boot
- so the fallback flush area will always be allocated
- so the check in init_fallback_flush() will always return early:
/* Only allocate the fallback flush area once (at boot time). */
if (l1d_flush_fallback_area)
return;
- and therefore we won't actually call the freed init routines.
We should rework the code to make it safer by default rather than
relying on the above, but for now as a quick-fix just add a __ref
annotation to squash the warning.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
