+Subject: [PATCH] tools: fix implicit declaration of function cpu_to_le16
+
+After commit 64d86c03e1441742216b6332bdfabfb6ede31662 ("perf arm-spe: Extend
+branch operations") which was also backported to the stable branches, the
+restructuring caused a missing definition.
+
+tools/include/linux/bitops.h implement
+
+define __MAKE_OP(size)                                                 \
+        ____MAKE_OP(le##size,u##size,cpu_to_le##size,le##size##_to_cpu) \
+        ____MAKE_OP(be##size,u##size,cpu_to_be##size,be##size##_to_cpu) \
+        ____MAKE_OP(u##size,u##size,,)
+____MAKE_OP(u8,u8,,)
+
+but cpu_to_le## or cpu_to_be## are not defined.
+
+Fix by including linux/kernel.h.
