| Thread-topic: | Avoid alloc for xsave before xsave_init |
While debugging some weird booting failure bugs, just found currently, xsave_alloc_save_area will be called in init_idle_domain->scheduler_init->alloc_vcpu->vcpu_initialise calls, it is earlier than xsave_init called in identity_cpu(). This may causing buffer overflow on xmem_pool. I am thinking about how to fix it.
