irq_fpu_usable() incorrectly returned true before the FPU is
initialized. The x86 CPU onlining code can call sha256() to checksum
AMD microcode images, before the FPU is initialized. Since sha256()
recently gained a kernel-mode FPU optimized code path, a crash occurred
in kernel_fpu_begin_mask() duri... | ```diff
