usercopy of 64 bit values does not work on 32-bit SPARC:
# usercopy_test_valid: EXPECTATION FAILED at lib/tests/usercopy_kunit.c:209
Expected val_u64 == 0x5a5b5c5d6a6b6c6d, but
val_u64 == 1515936861 (0x5a5b5c5d)
0x5a5b5c5d6a6b6c6d == 6510899242581322861 (0x5a5b5c5d6a6b6c6d)
Disable the test.

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.
