+Subject: [PATCH] BUILD: atomic: atomic.h may need compiler.h on ARMv8.2-a
+
+We get a build error in ncbuf.c when building for ARMv8.2-a because ncbuf
+has minimal includes and among them bug.h which includes atomic.h. Atomic.h
+may use "forceinline" without including compiler.h, hence the build error.
+It was verified that adding it doesn't inflate the total headers.
+
+Since all other C files include api.h which already covers this, there's
+no real need to bapkport this. The issue was already there in 2.3 though.
+
