Subject: [PATCH v4 57/57] mm: re-enable gcc frame address warning
Date: Thu, 18 Aug 2016 08:06:37 -0500 [thread overview]
Message-ID: <b258c0e92769ac32ed0dbddd7c1165b5d910276b.1471525031.git.jpoimboe@redhat.com> (raw)
In-Reply-To: <cover.1471525031.git.jpoimboe@redhat.com>
Now that arch_within_stack_frames()'s uses of __builtin_frame_address()
with non-zero arguments have been removed, this warning can be
re-enabled for mm code.
