  x86/build: Use obj-y to descend into arch/x86/virt/ (2024-03-30 10:41:49 +0100)

----------------------------------------------------------------
- Make sure single object builds in arch/x86/virt/ ala
    make ... arch/x86/virt/vmx/tdx/seamcall.o
  work again

- Do not do ROM range scans and memory validation when the kernel is
  running as a SEV-SNP guest as those can get problematic and, before
  that, are not really needed in such a guest

- Exclude the build-time generated vdso-image-x32.o object from objtool
  validation and in particular the return sites in there due to
  a warning which fires when an unpatched return thunk is being used

- Improve the NMI CPUs stall message to show additional information
  about the state of each CPU wrt the NMI handler

- Enable gcc named address spaces support only on !KCSAN configs due to
  compiler options incompatibility

- Revert a change which was trying to use GB pages for mapping regions
  only when the regions would be large enough but that change lead to
  kexec failing

- A documentation fixlet
