mm/filemap.c: In function 'clear_bit_unlock_is_negative_byte':
mm/filemap.c:1181:30: warning: passing argument 2 of 'test_bit' discards 'volatile' qualifier from pointer target type [-Wdiscarded-qualifiers]
return test_bit(PG_waiters, mem);

static inline int test_bit(int nr, const unsigned long *addr)
~~~~~~~~~~~~~~~~~~~~~^~~~
Make the bitmask pointed to by the "addr" parameter volatile to fix
this, like is done on other architectures.

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.
