Date: Fri, 7 Sep 2012 11:31:43 -0700 From: Suresh Siddha <suresh.b.siddha@...el.com> To: hpa@...or.com, mingo@...nel.org, torvalds@...ux-foundation.org, andreas.herrmann3@....com, bp@...64.org, robert.richter@....com Cc: linux-kernel@...r.kernel.org, Suresh Siddha <suresh.b.siddha@...el.com> Subject: [PATCH 3/3] x86, fpu: move check_fpu() after alternative_instructions() use_eager_fpu() in kernel_fpu_begin/end() relies on the patched alternative instructions. So move check_fpu() which uses the kernel_fpu_begin/end() after alternative_instructions().
