+Commit 71ae8aac ("lib: introduce arch optimized hash library")
+added an include to <linux/hash.h> for setting up an architecture
+specific fast hash. Since perf includes directly the non-uapi
+kernel header, it cannot find <asm/hash.h> on non-x86 and thus
+prevents perf to be compiled on every architecture other than
+x86. The problem is the inclusion of <asm/hash.h> in hash.h
+that results in the following error originating from
+util/evlist.c:
+
+  fatal error: asm/hash.h: No such file or directory
+
+This commit simply adds an empty <asm/hash.h> stub/file to fix
+the compile issue on non-x86 architectures. As perf does not use
+any of these new functions, it fixes the compilation and therefore
+seems to be the most appropriate solution to go with.
