The patch titled
Subject: selftest/fpu: avoid clang warning
has been removed from the -mm tree. Its filename was
selftest-fpu-avoid-clang-warning.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: selftest/fpu: avoid clang warning
With extra warnings enabled, clang complains about the redundant
-mhard-float argument:
clang: error: argument unused during compilation: '-mhard-float' [-Werror,-Wunused-command-line-argument]
Move this into the gcc-only part of the Makefile.
