Subject: [PATCH 184/208] x86/fpu: Move is_ia32*frame() helpers out of fpu/internal.h
Date: Tue, 5 May 2015 19:58:08 +0200 [thread overview]
Message-ID: <1430848712-28064-24-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1430848712-28064-1-git-send-email-mingo@kernel.org>
Move them to their only user. This makes the code easier to read,
the header is less cluttered, and it also speeds up the build a bit.
