Subject: [PATCH 5/6] hw_breakpoints: Only force perf events if breakpoints are selected
Date: Tue, 24 May 2011 23:52:26 +0200	[thread overview]
Message-ID: <1306273947-8410-6-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1306273947-8410-1-git-send-email-fweisbec@gmail.com>

Previously, arch were forced to always build perf events if they
supported hw_breakpoints.

Now that the user can choose not to build hw_breakpoints, let
only force perf events if hw_breakpoints are selected.
