Juergen Gross 64f142253b x86/xen: Fix secondary processors' FPU initialization 
commit fe3e0a13e597c1c8617814bf9b42ab732db5c26e upstream.

Moving the call of fpu__init_cpu() from cpu_init() to start_secondary()
broke Xen PV guests, as those don't call start_secondary() for APs.

Call fpu__init_cpu() in Xen's cpu_bringup(), which is the Xen PV
replacement of start_secondary().

Fixes: b81fac906a8f ("x86/fpu: Move FPU initialization into arch_cpu_finalize_init()")
