Subject: [PATCH 074/208] x86/fpu: Move MXCSR_DEFAULT to fpu/internal.h
Date: Tue,  5 May 2015 18:24:54 +0200	[thread overview]
Message-ID: <1430843228-13749-75-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1430843228-13749-1-git-send-email-mingo@kernel.org>

fpu/types.h gets included everywhere, move the MXCSR_DEFAULT to
fpu/internal.h, the place where it's used.
