Pull x86 fixes from Borislav Petkov:

 - Do not reserve SETUP_RNG_SEED setup data in the e820 map as it should
   be used by kexec only

 - Make sure MKTME feature detection happens at an earlier time in the
   boot process so that the physical address size supported by the CPU
   is properly corrected and MTRR masks are programmed properly, leading
   to TDX systems booting without disable_mtrr_cleanup on the cmdline

 - Make sure the different address sizes supported by the CPU are read
   out as early as possible
