Tom, you used the wrong GPL license header. Please fix that to be v2 not v3.

The

+# SPDX-License-Identifier: GPL-2.0

is correct but the adi-test.c one is not.

Add a selftest for the sparc64 privileged ADI driver.  These
tests verify the read(), pread(), write(), pwrite(), and seek()
functionality of the driver.  The tests also report simple
performance statistics:

         Syscall Call    AvgTime AvgSize
                 Count   (ticks) (bytes)
         -------------------------------
         read          3  119638    8133
         pread         4  118164    6741
         write         3  339442    8133
         pwrite        4  280134    6741
         seek         10    2919       0
         Pass 8 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0
