      KVM: fix poison overwritten caused by using wrong xstate size · f45755b8
      Xiaotian Feng 提交于
      fpu.state is allocated from task_xstate_cachep, the size of task_xstate_cachep
      is xstate_size. xstate_size is set from cpuid instruction, which is often
      smaller than sizeof(struct xsave_struct). kvm is using sizeof(struct xsave_struct)
      to fill in/out fpu.state.xsave, as what we allocated for fpu.state is
      xstate_size, kernel will write out of memory and caused poison/redzone/padding
      overwritten warnings.
