Subject: [PATCH v2 0/6] selftests/x86: fix build errors and warnings found via clang
Hi,
Just a bunch of build and warnings fixes that show up when
building with clang. Some of these depend on each other, so
I'm sending them as a series.
Changes since the first version:
1) Rebased onto Linux 6.10-rc1
Enjoy!
thanks,
John Hubbard
