Subject: [PATCH 4/6] hw_breakpoints: Breakpoints arch ability don't need perf events
Date: Tue, 24 May 2011 23:52:25 +0200 [thread overview]
Message-ID: <1306273947-8410-5-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1306273947-8410-1-git-send-email-fweisbec@gmail.com>
The breakpoint support ability in an arch is not related
to the fact perf events is built or not. HAVE_HW_BREAKPOINT
only shows an ability so this dependency makes no sense
anymore. Archs that select HAVE_HW_BREAKPOINT already
ensure that perf event is built.
Remove that dependency.
