  x86/sev: Ensure that RMP table fixups are reserved (2024-10-23 12:34:06 +0200)

----------------------------------------------------------------
- Prevent a certain range of pages which get marked as hypervisor-only, to get
  allocated to a CoCo (SNP) guest which cannot use them and thus fail booting

- Fix the microcode loader on AMD to pay attention to the stepping of a patch
  and to handle the case where a BIOS config option splits the machine into
  logical NUMA nodes per L3 cache slice

- Disable LAM from being built by default due to security concerns of
  a various kind
