Hi Shuah,

I've seen that from one of my contributors earlier this month as well. I
dropped the Content... Header and it applied without problems.

I created the patch using git format-patch and then sent them using git
send-email - via a script I've been using for years now...

Checking the files locally:
$ file *
0000-cover-letter.patch:                                         ASCII text
0001-selftests-Add-futex-functional-tests.patch:                 unified
diff output, UTF-8 Unicode text
0002-selftest-futex-Update-Makefile-to-use-lib.mk.patch:         unified
diff output, ASCII text
0003-selftest-futex-Increment-ksft-pass-and-fail-counters.patch: unified
diff output, ASCII text
0004-selftest-Add-futex-tests-to-the-top-level-Makefile.patch:   unified
diff output, ASCII text
0005-kselftest-Add-exit-code-defines.patch:                      unified
diff output, ASCII text


This shows that only the first in UTF-8 and the rest are ASCII. I presume
this is due to the Copyright notices in the original files:

Copyright © International Business Machines  Corp., 2006-2008

Which use © instead of (C). I just checked and there are 545 instances of
© in the kernel itself, so this should not present a problem.

I apologize for the glitch in applying. If you use the pull request I
included that will avoid the mail transport issues, and I will be sure to
fix my scripts to avoid the issue in the future.

If you want to use the patches directly, please have a look at 1 of 5 and
just remove the "Content..." header, and I think you'll find "git am" will
apply it without complaint.

Thanks,
