    x86/fpu: Remove xsave_init() bootmem allocations · 966ece61
    Ingo Molnar authored
    There's only 8 xstate bits at the moment, and it's not like we
    can support unknown bits - so put xstate_offsets[] and
    xstate_sizes[] into static allocation.
    
    This is in preparation to be able to call the FPU init code
    earlier, when there's no bootmem available yet.
