3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Linus Torvalds <[email protected]> commit c38e23456278e967f094b08247ffc3711b1029b2 upstream. The check for save_init_fpu() (introduced in commit 5b1cbac37798: "i387: make irq_fpu_usable() tests more robust") was the wrong way around, but I hadn't noticed, because my "tests" were bogus: the FPU exceptions are disabled by default, so even doing a divide by zero never actually triggers this code at all unless you do extra work to enable them. So if anybody did enable them, they'd get one spurious warning.
