Subject: [PATCH 03/12] perf tools: Fix include for non x86 architectures
Date: Fri, 31 Jan 2014 17:27:26 -0300	[thread overview]
Message-ID: <1391200055-18250-4-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1391200055-18250-1-git-send-email-acme@infradead.org>

From: Francesco Fusco <ffusco@redhat.com>

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.
