e63d32ac02 hv: delay enabling SMEP/SMAP until the end of PCPU initialization
Host ACPI parsing is needed during initialization only, not in run time.
Hence we don't need to clear U flag for memory in reserved or ACPI type
E820 entries.

- move enable_smep() and enable_smap() to the end of init_pcpu_post(),
  so stac()/clac() can be removed from any init code before this point.

- call init_seed() before init_pcpu_post(), and rmeove stac()/clac() from
  init_seed().
